Unidentified flying object(ufo)- PART I
Unidentified flying object(ufo)- PART I
An unidentified flying object or "UFO" is an object perceived in the sky that is not readily identified. Most UFOs are later identified as conventional objects or phenomena. The term is widely used for claimed observations of extraterrestrial craft.

An unidentified flying object or "UFO" is an object perceived in the sky that is not readily identified. Most UFOs are later identified as conventional objects or phenomena. The term is widely used for claimed observations of extraterrestrial craft.
Terminology
The term "UFO" (or "UFOB") was coined in 1953 by the United States Air Force (USAF) to serve as a catch-all for all such reports. In its initial definition, the USAF stated that a "UFOB" was "any airborne object which by performance, aerodynamic characteristics, or unusual features, does not conform to any presently known aircraft or missile type, or which cannot be positively identified as a familiar object." Accordingly, the term was initially restricted to that fraction of cases which remained unidentified after investigation, as the USAF was interested in potential national security reasons and/or "technical aspects" (see Air Force Regulation 200-2).
During the late 1940s and through the 1950s, UFOs were often referred to popularly as "flying saucers" or "flying discs". The term UFO became more widespread during the 1950s, at first in technical literature, but later in popular use. UFOs garnered considerable interest during the Cold War, an era associated with a heightened concern for national security, and, more recently, in the 2010s, for unexplained reasons.[1][2] Nevertheless, various studies have concluded that the phenomenon does not represent a threat to national security, nor does it contain anything worthy of scientific pursuit (e.g., 1951 Flying Saucer Working Party, 1953 CIARobertson Panel, USAF Project Blue Book, Condon Committee).
The Oxford English Dictionary defines a UFO as "An unidentified flying object; a 'flying saucer'." The first published book to use the word was authored by Donald E. Keyhoe.[3]
The acronym "UFO" was coined by Captain Edward J. Ruppelt, who headed Project Blue Book, then the USAF's official investigation of UFOs. He wrote, "Obviously the term 'flying saucer' is misleading when applied to objects of every conceivable shape and performance. For this reason the military prefers the more general, if less colorful, name: unidentified flying objects. UFO (pronounced Yoo-foe) for short."[4] Other phrases that were used officially and that predate the UFO acronym include "flying flapjack", "flying disc", "unexplained flying discs", and "unidentifiable object".[5][6][7]
The phrase "flying saucer" had gained widespread attention after the summer of 1947. On June 24, a civilian pilot named Kenneth Arnold reported seeing nine objects flying in formation near Mount Rainier. Arnold timed the sighting and estimated the speed of discs to be over 1,200 mph (1,931 km/h). At the time, he claimed he described the objects flying in a saucer-like fashion, leading to newspaper accounts of "flying saucers" and "flying discs".[8][9]
In popular usage, the term UFO came to be used to refer to claims of alien spacecraft.[3] and because of the public and media ridicule associated with the topic, some ufologists and investigators prefer to use terms such as "unidentified aerial phenomenon" (UAP) or "anomalous phenomena", as in the title of the National Aviation Reporting Center on Anomalous Phenomena (NARCAP).[10] "Anomalous aerial vehicle" (AAV) or "unidentified aerial system" (UAS) are also sometimes used in a military aviation context to describe unidentified targets.[11]
Studies
Studies have established that the majority of UFO observations are misidentified conventional objects or natural phenomena—most commonly aircraft, balloons, noctilucent clouds, nacreous clouds, or astronomical objects such as meteors or bright planets with a small percentage even being hoaxes.[note 1] Between 5% and 20% of reported sightings are not explained, and therefore can be classified as unidentified in the strictest sense. While proponents of the extraterrestrial hypothesis (ETH) suggest that these unexplained reports are of alien spacecraft, the null hypothesis cannot be excluded that these reports are simply other more prosaic phenomena that cannot be identified due to lack of complete information or due to the necessary subjectivity of the reports.
Almost no scientific papers about UFOs have been published in peer-reviewed journals.[12] There was, in the past, some debate in the scientific community about whether any scientific investigation into UFO sightings is warranted with the general conclusion being that the phenomenon was not worthy of serious investigation except as a cultural artifact.[13][14][15][16][17][18][19] UFOs have been the subject of investigations by various governments who have provided extensive records related to the subject. Many of the most involved government-sponsored investigations ended after agencies concluded that there was no benefit to continued investigation.[20][21]
The void left by the lack of institutional or scientific study has given rise to independent researchers and fringe groups, including the National Investigations Committee on Aerial Phenomena (NICAP) in the mid-20th century and, more recently, the Mutual UFO Network (MUFON)[22] and the Center for UFO Studies (CUFOS).[23] The term "Ufology" is used to describe the collective efforts of those who study reports and associated evidence of unidentified flying objects.[24]
UFOs have become a prevalent theme in modern culture,[25] and the social phenomena have been the subject of academic research in sociology and psychology.[12]
Early history
Unexplained aerial observations have been reported throughout history. Some were undoubtedly astronomical in nature: comets, bright meteors, one or more of the five planets that can be readily seen with the naked eye, planetary conjunctions, or atmospheric optical phenomena such as parhelia and lenticular clouds. An example is Halley's Comet, which was recorded first by Chinese astronomers in 240 BC and possibly as early as 467 BC. Such sightings throughout history often were treated as supernatural portents, angels, or other religious omens. Some current-day UFO researchers have noticed similarities between some religious symbols in medieval paintings and UFO reports[26] though the canonical and symbolic character of such images is documented by art historians placing more conventional religious interpretations on such images.[27]
On April 14, 1561, residents of Nuremberg described the appearance of a large black triangular object. According to witnesses, there were also hundreds of spheres, cylinders and other odd-shaped objects that moved erratically overhead.[28]
On January 25, 1878, the Denison Daily News printed an article in which John Martin, a local farmer, had reported seeing a large, dark, circular object resembling a balloon flying "at wonderful speed." Martin, according to the newspaper account, said it appeared to be about the size of a saucer, the first known use of the word "saucer" in association with a UFO.[29]
In April 1897, thousands of people reported seeing "airships" in various parts of the United States. Many signed affidavits. Scores of people even reported talking to the pilots. Thomas Edison was asked his opinion, and said, "You can take it from me that it is a pure fake."[30][31]
On February 28, 1904, there was a sighting by three crew members on the USS Supply 300 miles (483 km) west of San Francisco, reported by Lieutenant Frank Schofield, later to become Commander-in-Chief of the Pacific Battle Fleet. Schofield wrote of three bright red egg-shaped and circular objects flying in echelon formation that approached beneath the cloud layer, then changed course and "soared" above the clouds, departing directly away from the earth after two to three minutes. The largest had an apparent size of about six Suns, he said.[32][33]
The three earliest known pilot UFO sightings, of 1,305 similar sightings catalogued by NARCAP, took place in 1916 and 1926. On January 31, 1916, a UK pilot near Rochfordreported a row of lights, resembling lighted windows on a railway carriage, that rose and disappeared. In January 1926 a pilot reported six "flying manhole covers" between Wichita, Kansas, and Colorado Springs, Colorado. In late September 1926 an airmail pilot over Nevada said he had been forced to land by a huge, wingless, cylindrical object.[34]
On August 5, 1926, while traveling in the Humboldt Mountains of Tibet's Kokonor region, Russian explorer Nicholas Roerich reported, members of his expedition saw "something big and shiny reflecting the sun, like a huge oval moving at great speed. Crossing our camp the thing changed in its direction from south to southwest. And we saw how it disappeared in the intense blue sky. We even had time to take our field glasses and saw quite distinctly an oval form with shiny surface, one side of which was brilliant from the sun."[35] Another description by Roerich was of a "shiny body flying from north to south. Field glasses are at hand. It is a huge body. One side glows in the sun. It is oval in shape. Then it somehow turns in another direction and disappears in the southwest."[36]
In the Pacific and European theatres during World War II, "foo fighters" (metallic spheres, balls of light and other shapes that followed aircraft) were reported and on occasion photographed by Allied and Axis pilots. Some proposed Allied explanations at the time included St. Elmo's fire, the planet Venus, hallucinations from oxygen deprivation, or German secret weapons.[37][38]
In 1946, more than 2,000 reports were collected, primarily by the Swedish military, of unidentified aerial objects over the Scandinavian nations, along with isolated reports from France, Portugal, Italy and Greece. The objects were referred to as "Russian hail" and later as "ghost rockets" because it was thought that the mysterious objects were possibly Russian tests of captured German V1 or V2rockets. Although most were thought to be such natural phenomena as meteors, more than 200 were tracked on radar by the Swedish military and deemed to be "real physical objects." In a 1948 top secret document, Swedish authorities advised the USAF Europe that some of their investigators believed these craft to be extraterrestrial in origin.[39]
Investigations
UFOs have been subject to investigations over the years that varied widely in scope and scientific rigor. Governments or independent academics in the United States, Canada, the United Kingdom, Japan, Peru, France, Belgium, Sweden, Brazil, Chile, Uruguay, Mexico, Spain, and the Soviet Union are known to have investigated UFO reports at various times.
Project Sign in 1948 produced a highly classified finding (see Estimate of the Situation) that the best UFO reports probably had an extraterrestrial explanation. A top secret Swedish military opinion given to the USAF in 1948 stated that some of their analysts believed that the 1946 ghost rockets and later flying saucers had extraterrestrial origins. (For document, see Ghost rockets.) In 1954 German rocket scientist Hermann Oberth revealed that an internal West German government investigation, which he headed, had arrived at an extraterrestrial conclusion, but this study was never made public.
Project Sign was dismantled and became Project Grudge at the end of 1948. Angered by the low quality of investigations by Grudge, the Air Force Director of Intelligence reorganized it as Project Blue Book in late 1951, placing Ruppelt in charge. Blue Book closed down in 1970, using the Condon Committee's negative conclusion as a rationale, thus ending official Air Force UFO investigations. However, a 1969 USAF document, known as the Bolender memo, along with later government documents, revealed that non-public U.S. government UFO investigations continued after 1970. The Bolender memo first stated that "reports of unidentified flying objects that could affect national security ... are not part of the Blue Book system," indicating that more serious UFO incidents already were handled outside the public Blue Book investigation. The memo then added, "reports of UFOs which could affect national security would continue to be handled through the standard Air Force procedures designed for this purpose."[note 2] In addition, in the late 1960s a chapter on UFOs in the Space Sciences course at the U.S. Air Force Academy gave serious consideration to possible extraterrestrial origins. When word of the curriculum became public, the Air Force in 1970 issued a statement to the effect that the book was outdated and that cadets instead were being informed of the Condon Report's negative conclusion.[41]
USAF Regulation 200-2
Air Force Regulation 200-2,[42] issued in 1953 and 1954, defined an Unidentified Flying Object ("UFOB") as "any airborne object which by performance, aerodynamic characteristics, or unusual features, does not conform to any presently known aircraft or missile type, or which cannot be positively identified as a familiar object." The regulation also said UFOBs were to be investigated as a "possible threat to the security of the United States" and "to determine technical aspects involved." The regulation went on to say that "it is permissible to inform news media representatives on UFOB's when the object is positively identified as a familiar object," but added: "For those objects which are not explainable, only the fact that ATIC [Air Technical Intelligence Center] will analyze the data is worthy of release, due to many unknowns involved."[42]
J. Allen Hynek, a trained astronomer who served as a scientific advisor for Project Blue Book, was initially skeptical of UFO reports, but eventually came to the conclusion that many of them could not be satisfactorily explained and was highly critical of what he described as "the cavalier disregard by Project Blue Book of the principles of scientific investigation."[43] Leaving government work, he founded the privately funded CUFOS, to whose work he devoted the rest of his life. Other private groups studying the phenomenon include the MUFON, a grass roots organization whose investigator's handbooks go into great detail on the documentation of alleged UFO sightings.
Like Hynek, Jacques Vallée, a scientist and prominent UFO researcher, has pointed to what he believes is the scientific deficiency of most UFO research, including government studies. He complains of the mythology and cultism often associated with the phenomenon, but alleges that several hundred professional scientists—a group both he and Hynek have termed "the invisible college"—continue to study UFOs in private.[25]
Scientific studies
The study of UFOs has received little support in mainstream scientific literature. Official studies ended in the U.S. in December 1969, following the statement by the government scientist Edward Condon that further study of UFOs could not be justified on grounds of scientific advancement.[15][44] The Condon Report and its conclusions were endorsed by the National Academy of Scientists, of which Condon was a member. On the other hand, a scientific review by the UFO subcommittee of the American Institute of Aeronautics and Astronautics (AIAA) disagreed with Condon's conclusion, noting that at least 30 percent of the cases studied remained unexplained and that scientific benefit might be gained by continued study.
Critics argue that all UFO evidence is anecdotal[45] and can be explained as prosaic natural phenomena. Defenders of UFO research counter that knowledge of observational data, other than what is reported in the popular media, is limited in the scientific community and that further study is needed.[25][46]
No official government investigation has ever publicly concluded that UFOs are indisputably real, physical objects, extraterrestrial in origin, or of concern to national defense. These same negative conclusions also have been found in studies that were highly classified for many years, such as the UK's Flying Saucer Working Party, Project Condign, the U.S. CIA-sponsored Robertson Panel, the U.S. military investigation into the green fireballs from 1948 to 1951, and the Battelle Memorial Institute study for the USAF from 1952 to 1955 (Project Blue Book Special Report No. 14).
Some public government reports have acknowledged the possibility of physical reality of UFOs, but have stopped short of proposing extraterrestrial origins, though not dismissing the possibility entirely. Examples are the Belgian military investigation into large triangles over their airspace in 1989–1991 and the 2009 Uruguayan Air Force study conclusion (see below).
Some private studies have been neutral in their conclusions, but argued that the inexplicable core cases call for continued scientific study. Examples are the Sturrock panel study of 1998 and the 1970 AIAA review of the Condon Report.
United States
U.S. investigations into UFOs include:
The Interplanetary Phenomenon Unit (IPU), established by the U.S. Army sometime in the 1940s, and about which little is known. In 1987, British UFO researcher Timothy Good received from the Army's director of counter-intelligence a letter confirming the existence of the IPU. The letter stated that "the aforementioned Army unit was disestablished during the late 1950s and never reactivated. All records pertaining to this unit were surrendered to the U.S. Air Force Office of Special Investigations in conjunction with operation BLUEBOOK." The IPU records have never been released.[47]
Project Blue Book, previously Project Sign and Project Grudge, conducted by the USAF from 1947 until 1969
The secret U.S. Army/Air Force Project Twinkle investigation into green fireballs (1948–1951)
Ghost rockets investigations by the Swedish, UK, U.S., and Greek militaries (1946–1947)
The secret CIA Office of Scientific Investigation (OS/I) study (1952–53)
Thousands of documents released under FOIA also indicate that many U.S. intelligence agencies collected (and still collect) information on UFOs. These agencies include the Defense Intelligence Agency (DIA), FBI,[7] CIA, National Security Agency (NSA), as well as military intelligence agencies of the Army and U.S. Navy, in addition to the Air Force.[note 3]
The investigation of UFOs has also attracted many civilians, who in the U.S formed research groups such as NICAP (active 1956–1980), Aerial Phenomena Research Organization(APRO) (active 1952–1988), MUFON (active 1969–), and CUFOS (active 1973–).
In November 2011, the White House released an official response to two petitions asking the U.S. government to acknowledge formally that aliens have visited this planet and to disclose any intentional withholding of government interactions with extraterrestrial beings. According to the response, "The U.S. government has no evidence that any life exists outside our planet, or that an extraterrestrial presence has contacted or engaged any member of the human race."[50][51] Also, according to the response, there is "no credible information to suggest that any evidence is being hidden from the public's eye."[50][51] The response further noted that efforts, like SETI and NASA's Kepler space telescope and Mars Science Laboratory, continue looking for signs of life. The response noted "odds are pretty high" that there may be life on other planets but "the odds of us making contact with any of them—especially any intelligent ones—are extremely small, given the distances involved."[50][51]
Post-1947 sightings
Following the large U.S. surge in sightings in June and early July 1947, on July 9, 1947, United States Army Air Forces (USAAF) intelligence, in cooperation with the FBI,[7] began a formal investigation into selected sightings with characteristics that could not be immediately rationalized, such as Kenneth Arnold's. The USAAF used "all of its top scientists" to determine whether "such a phenomenon could, in fact, occur." The research was "being conducted with the thought that the flying objects might be a celestial phenomenon," or that "they might be a foreign body mechanically devised and controlled."[52] Three weeks later in a preliminary defense estimate, the air force investigation decided that, "This 'flying saucer' situation is not all imaginary or seeing too much in some natural phenomenon. Something is really flying around."[53]
A further review by the intelligence and technical divisions of the Air Materiel Command at Wright Field reached the same conclusion. It reported that "the phenomenon is something real and not visionary or fictitious," that there were objects in the shape of a disc, metallic in appearance, and as big as man-made aircraft. They were characterized by "extreme rates of climb [and] maneuverability," general lack of noise, absence of trail, occasional formation flying, and "evasive" behavior "when sighted or contacted by friendly aircraft and radar," suggesting a controlled craft. It was therefore recommended in late September 1947 that an official Air Force investigation be set up to investigate the phenomenon. It was also recommended that other government agencies should assist in the investigation.[note 4]
Project Sign
This led to the creation of the Air Force's Project Sign at the end of 1947, one of the earliest government studies to come to a secret extraterrestrial conclusion. In August 1948, Sign investigators wrote a top-secret intelligence estimate to that effect, but the Air Force Chief of StaffHoyt Vandenberg ordered it destroyed. The existence of this suppressed report was revealed by several insiders who had read it, such as astronomer and USAF consultant J. Allen Hynek and Capt. Edward J. Ruppelt, the first head of the USAF's Project Blue Book.[54]
Another highly classified U.S. study was conducted by the CIA's Office of Scientific Investigation (OS/I) in the latter half of 1952 in response to orders from the National Security Council (NSC). This study concluded UFOs were real physical objects of potential threat to national security. One OS/I memo to the CIA Director (DCI) in December read:
the reports of incidents convince us that there is something going on that must have immediate attention ... Sightings of unexplained objects at great altitudes and traveling at high speeds in the vicinity of major U.S. defense installations are of such a nature that they are not attributable to natural phenomena or any known types of aerial vehicles.
The matter was considered so urgent that OS/I drafted a memorandum from the DCI to the NSC proposing that the NSC establish an investigation of UFOs as a priority project throughout the intelligence and the defense research and development community. It also urged the DCI to establish an external research project of top-level scientists, now known as the Robertson Panel to analyze the problem of UFOs. The OS/I investigation was called off after the Robertson Panel's negative conclusions in January 1953.[55]
A public research effort conducted by the Condon Committee for the USAF, which arrived at a negative conclusion in 1968, marked the end of the U.S. government's official investigation of UFOs, though various government intelligence agencies continue unofficially to investigate or monitor the situation.[note 5]
Controversy has surrounded the Condon Report, both before and after it was released. It has been observed that the report was "harshly criticized by numerous scientists, particularly at the powerful AIAA ... [which] recommended moderate, but continuous scientific work on UFOs."[15] In an address to the AAAS, James E. McDonald stated that he believed science had failed to mount adequate studies of the problem and criticized the Condon Report and earlier studies by the USAF as scientifically deficient. He also questioned the basis for Condon's conclusions[56] and argued that the reports of UFOs have been "laughed out of scientific court."[14] J. Allen Hynek, an astronomer who worked as a USAF consultant from 1948, sharply criticized the Condon Committee Report and later wrote two nontechnical books that set forth the case for continuing to investigate UFO reports.
Ruppelt recounted his experiences with Project Blue Book, a USAF investigation that preceded Condon's.[57]
Notable cases
The Roswell UFO incident (1947) involved New Mexico residents, local law enforcement officers, and the U.S. military, the latter of whom allegedly collected physical evidence from the UFO crash site.
In the Kecksburg UFO incident, Pennsylvania (1965), residents reported seeing a bell shaped object crash in the area. Police officers, and possibly military personnel, were sent to investigate.
The Travis Walton abduction case (1975): The movie Fire in the Sky (1993) was based on this event, but greatly embellished the original account.
Document on sighting of a UFO occurred on December 16, 1977, in the state of Bahia, Brazil.
Brazil
On October 31, 2008, the National Archives of Brazil began receiving from the Aeronautical Documentation and History Center part of the documentation of the Brazilian Air Force regarding the investigation of the appearance of UFOs in Brazil. Currently this collection gathers cases between 1952 and 2016.[58]
An unidentified flying object or "UFO" is an object perceived in the sky that is not readily identified. Most UFOs are later identified as conventional objects or phenomena. The term is widely used for claimed observations of extraterrestrial craft.
France
On March 2007, the French space agency CNES published an archive of UFO sightings and other phenomena online.[60]
French studies include GEPAN/SEPRA/GEIPAN (1977–), within CNES (French space agency), the longest ongoing government-sponsored investigation. About 22% of 6000 cases studied remain unexplained.[61] The official opinion of GEPAN/SEPRA/GEIPAN has been neutral, stating on their FAQ page that their mission is fact-finding for the scientific community, not rendering an opinion. They add they can neither prove nor disprove the Exterrestrial Hypothesis (ETH), but their Steering Committee's clear position is that they cannot discard the possibility that some fraction of the very strange 22% of unexplained cases might be due to distant and advanced civilizations.[62] Possibly their bias may be indicated by their use of the terms "PAN" (French) or "UAP" (English equivalent) for "Unidentified Aerospace Phenomenon" (whereas "UAP" as normally used by English organizations stands for "Unidentified Aerial Phenomenon", a more neutral term). In addition, the three heads of the studies have gone on record in stating that UFOs were real physical flying machines beyond our knowledge or that the best explanation for the most inexplicable cases was an extraterrestrial one.[63][64][65]
In 2008, Michel Scheller, president of the Association Aéronautique et Astronautique de France (3AF), created the Sigma Commission. Its purpose was to investigate UFO phenomenon worldwide.[66] A progress report published in May 2010 stated that the central hypothesis proposed by the COMETA report is perfectly credible.[67] In December 2012, the final report of the Sigma Commission was submitted to Scheller. Following the submission of the final report, the Sigma2 Commission is to be formed with a mandate to continue the scientific investigation of UFO phenomenon.[68][69]
According to some Italian ufologists, the first documented case of a UFO sighting in Italy dates back to April 11, 1933, to Varese. Documents of the time show that an alleged UFO crashed or landed near Vergiate. Following this, Benito Mussolini created a secret group to look at it, called Cabinet RS/33.[70][71]
Alleged UFO sightings gradually increased since the war, peaking in 1978 and 2005. The total number of sightings since 1947 are 18,500, of which 90% are identifiable.[72]
In 2000, Italian ufologist Roberto Pinotti published material regarding the so-called "Fascist UFO Files", which dealt with a flying saucer that had crashed near Milan in 1933 (some 14 years before the Roswell, New Mexico, crash), and of the subsequent investigation by a never mentioned before Cabinet RS/33, that allegedly was authorized by Benito Mussolini, and headed by the Nobel scientist Guglielmo Marconi. A spaceship was allegedly stored in the hangars of the SIAI Marchetti in Vergiate near Milan.[73]
Julius Obsequens was a Roman writer who is believed to have lived in the middle of the fourth century AD. The only work associated with his name is the Liber de prodigiis (Book of Prodigies), completely extracted from an epitome, or abridgment, written by Livy; De prodigiis was constructed as an account of the wonders and portents that occurred in Romebetween 249 BC-12 BC. An aspect of Obsequens' work that has inspired much interest in some circles is that references are made to things moving through the sky. These have been interpreted as reports of UFOs, but may just as well describe meteors, and, since Obsequens, probably, writes in the 4th century, that is, some 400 years after the events he describes, they hardly qualify as eye-witness accounts.[74][75]
In 1973, an Alitalia airplane left Rome for Naples sighted a mysterious round object. Two Italian Air Force planes from Ciampino confirmed the sighting.[77] In the same year there was another sighting at Caselle airport near Turin.[78]
In 1978, two young hikers, while walking on Monte Musinè near Turin, saw a bright light; one of them temporarily disappeared and, after a while, was found in a state of shock and with a noticeable scald on one leg. After regaining consciousness, he reported having seen an elongated vehicle and that some strangely shaped beings descended from it. Both the young hikers suffered from conjunctivitis for some time.[79]
A close encounter reported in September 1978 in Torrita di Siena in the Province of Siena. A young motorist saw in front of him a bright object, two beings of small stature who wore suits and helmets, the two approached the car, and after watching it carefully went back and rose again to the UFO. A boy who lived with his family in a country house not far from there said he had seen at the same time "a kind of small reddish sun".[80]
Yet in 1978, there has been also the story of Pier Fortunato Zanfretta, the best known and most controversial case of an Italian alleged alien abduction. Zanfretta said to have been kidnapped on the night of 6 December and 7 December while he was performing his job at Marzano, in the municipality of Torriglia in the Province of Genoa;[81] 52 testimonies of the case from other people were collected.[81]
United Kingdom
The UK's Flying Saucer Working Party published its final report in June 1951, which remained secret for over 50 years. The Working Party concluded that all UFO sightings could be explained as misidentifications of ordinary objects or phenomena, optical illusions, psychological misperceptions/aberrations, or hoaxes. The report stated: "We accordingly recommend very strongly that no further investigation of reported mysterious aerial phenomena be undertaken, unless and until some material evidence becomes available."[82]
Eight file collections on UFO sightings, dating from 1978 to 1987, were first released on May 14, 2008, to The National Archives by the Ministry of Defence (MoD).[83] Although kept secret from the public for many years, most of the files have low levels of classification and none are classified Top Secret. 200 files are set to be made public by 2012. The files are correspondence from the public sent to the British government and officials, such as the MoD and Margaret Thatcher. The MoD released the files under the Freedom of Information Act due to requests from researchers.[84] These files include, but are not limited to, UFOs over Liverpool and the Waterloo Bridge in London.[85]
On October 20, 2008, more UFO files were released. One case released detailed that in 1991 an Alitalia passenger aircraft was approaching London Heathrow Airport when the pilots saw what they described as a "cruise missile" fly extremely close to the cockpit. The pilots believed that a collision was imminent. UFO expert David Clarke says that this is one of the most convincing cases for a UFO he has come across.[86]
A secret study of UFOs was undertaken for the Ministry of Defence between 1996 and 2000 and was code-named Project Condign. The resulting report, titled "Unidentified Aerial Phenomena in the UK Defence Region", was publicly released in 2006, but the identity and credentials of whomever constituted Project Condign remains classified. The report confirmed earlier findings that the main causes of UFO sightings are misidentification of man-made and natural objects. The report noted: "No artefacts of unknown or unexplained origin have been reported or handed to the UK authorities, despite thousands of Unidentified Aerial Phenomena reports. There are no SIGINT, ELINT or radiation measurements and little useful video or still IMINT." It concluded: "There is no evidence that any UAP, seen in the UKADR [UK Air Defence Region], are incursions by air-objects of any intelligent (extraterrestrial or foreign) origin, or that they represent any hostile intent." A little-discussed conclusion of the report was that novel meteorological plasma phenomenon akin to ball lightning are responsible for "the majority, if not all" of otherwise inexplicable sightings, especially reports of black triangle UFOs.[87]
On December 1, 2009, the Ministry of Defence quietly closed down its UFO investigations unit. The unit's hotline and email address were suspended by the MoD on that date. The MoD said there was no value in continuing to receive and investigate sightings in a release, stating
in over fifty years, no UFO report has revealed any evidence of a potential threat to the United Kingdom. The MoD has no specific capability for identifying the nature of such sightings. There is no Defence benefit in such investigation and it would be an inappropriate use of defence resources. Furthermore, responding to reported UFO sightings diverts MoD resources from tasks that are relevant to Defence."
The Guardian reported that the MoD claimed the closure would save the Ministry around £50,000 a year. The MoD said that it would continue to release UFO files to the public through The National Archives.[88]
Notable cases
According to records released on August 5, 2010, British wartime prime minister Winston Churchill banned the reporting for 50 years of an alleged UFO incident because of fears it could create mass panic. Reports given to Churchill asserted that the incident involved a Royal Air Force (RAF) reconnaissance aircraft returning from a mission in France or Germany toward the end of World War II. It was over or near the English coastline when it was allegedly intercepted by a strange metallic object that matched the aircraft's course and speed for a time before accelerating away and disappearing. The aircraft's crew were reported to have photographed the object, which they said had "hovered noiselessly" near the aircraft, before moving off.[89] According to the documents, details of the coverup emerged when a man wrote to the government in 1999 seeking to find out more about the incident and described how his grandfather, who had served with the RAF in the war, was present when Churchill and U.S. General Dwight D. Eisenhower discussed how to deal with the UFO encounter.[90][91] The files come from more than 5,000 pages of UFO reports, letters and drawings from members of the public, as well as questions raised in Parliament. They are available to download from The National Archives website.[83]
In the April 1957 West Freugh incident in Scotland, named after the principal military base involved, two unidentified objects flying high over the UK were tracked by radar operators. The objects were reported to operate at speeds and perform maneuvers beyond the capability of any known craft. Also significant is their alleged size, which – based on the radar returns – was closer to that of a ship than an aircraft.
In the Rendlesham Forest incident of December 1980, U.S. military personnel witnessed UFOs near the air base at Woodbridge, Suffolk, over a period of three nights. On one night the deputy base commander, Colonel Charles I. Halt, and other personnel followed one or more UFOs that were moving in and above the forest for several hours. Col. Halt made an audio recording while this was happening and subsequently wrote an official memorandum summarizing the incident. After retirement from the military, he said that he had deliberately downplayed the event (officially termed 'Unexplained Lights') to avoid damaging his career. Other base personnel are said to have observed one of the UFOs, which had landed in the forest, and even gone up to and touched it.
Uruguay
The Uruguayan Air Force has conducted UFO investigations since 1989 and reportedly analyzed 2,100 cases of which they regard approximately 2% as lacking explanation.[92]
Astronomer reports
The USAF's Project Blue Book files indicate that approximately 1%[93] of all unknown reports came from amateur and professional astronomers or other users of telescopes (such as missile trackers or surveyors). In 1952, astronomer J. Allen Hynek, then a consultant to Blue Book, conducted a small survey of 45 fellow professional astronomers. Five reported UFO sightings (about 11%). In the 1970s, astrophysicist Peter A. Sturrock conducted two large surveys of the AIAA and American Astronomical Society (AAS). About 5% of the members polled indicated that they had had UFO sightings.
Astronomer Clyde Tombaugh, who admitted to six UFO sightings, including three green fireballs, supported the Extraterrestrial hypothesis for UFOs and stated he thought scientists who dismissed it without study were being "unscientific." Another astronomer was Lincoln LaPaz, who had headed the Air Force's investigation into the green fireballs and other UFO phenomena in New Mexico. LaPaz reported two personal sightings, one of a green fireball, the other of an anomalous disc-like object. (Both Tombaugh and LaPaz were part of Hynek's 1952 survey.) Hynek himself took two photos through the window of a commercial airliner of a disc-like object that seemed to pace his aircraft.[94]
In 1980, a survey of 1800 members of various amateur astronomer associations by Gert Helb and Hynek for CUFOS found that 24% responded "yes" to the question "Have you ever observed an object which resisted your most exhaustive efforts at identification?"[95]
Claims of increase in reports
MUFON reports that UFO sightings to their offices have increased by 67% in the previous three years as of 2011. According to MUFON international director Clifford Clift in 2011, "Over the past year, we've been averaging 500 sighting reports a month, compared to about 300 three years ago [67 percent],".[96][97]
According to the annual survey of reports conducted by Canadian-based UFO research group Ufology Research, reported UFO sightings doubled in Canada between 2011 and 2012.[98][99]
In 2013 the Peruvian government's Departamento de Investigación de Fenómenos Aéreos Anómalos (Anomalous Aerial Phenomena Research Department), or "DIFAA", was officially reactivated due to an increase in reported sightings. According to Colonel Julio Vucetich, head of the air force's aerospace interests division who himself claims to have seen an "anomalous aerial object", "On a personal basis, it's evident to me that we are not alone in this world or universe."[100][101]
Fata Morgana, a type of mirage in which objects located below the astronomical horizon appear to be hovering in the sky just above the horizon, may be responsible for some UFO sightings. (Here, the shape floating above the horizon is the reflected image of a boat.) Fata Morgana can also distort the appearance of distant objects, sometimes making them unrecognizable[103]
Lenticular clouds have in some cases been reported as UFOs due to their peculiar shape
Studies show that after careful investigation, the majority of UFOs can be identified as ordinary objects or phenomena. The most commonly found identified sources of UFO reports are:
A 1952–1955 study by the Battelle Memorial Institute for the USAF included these categories as well as a "psychological" one.
An individual 1979 study by CUFOS researcher Allan Hendry found, as did other investigations, that only a small percentage of cases he investigated were hoaxes (<1 and="" that="" most="" sightings="" were="" actually="" honest="" misidentifications="" of="" prosaic="" phenomena="" hendry="" attributed="" these="" to="" inexperience="" or="" misperception="" sup="" class="reference" id="cite_ref-109">[104]
Claims by military, government, and aviation personnel
Since 2001 there have been calls for greater openness on the part of the government by various persons. In May 2001, a press conference was held at the National Press Club in Washington, D.C., by an organization called the Disclosure Project, featuring twenty persons including retired Air Force and FAA personnel, intelligence officers and an air traffic controller.[105][106][107][108][109][110][111] They all gave a brief account of what they knew or had witnessed, and stated that they would be willing to testify to what they had said under oath to a Congressional committee. According to a 2002 report in the Oregon Daily Emerald, Disclosure Project founder Steven M. Greer has gathered 120 hours of testimony from various government officials on the topic of UFOs, including astronaut Gordon Cooper and a Brigadier General.[112]
In 2007, former Arizona governor Fife Symington came forward and belatedly claimed that he had seen "a massive, delta-shaped craft silently navigate over Squaw Peak, a mountain range in Phoenix, Arizona" in 1997.[113]
On September 27, 2010, a group of six former USAF officers and one former enlisted Air Force man held a press conference at the National Press Club in Washington, D.C., on the theme "U.S. Nuclear Weapons Have Been Compromised by Unidentified Aerial Objects."[114] They told how they had witnessed UFOs hovering near missile sites and even disarming the missiles.
From April 29 to May 3, 2013, the Paradigm Research Group held the "Citizen Hearing on Disclosure" at the National Press Club. The group paid former U.S. Senator Mike Graveland former Representatives Carolyn Cheeks Kilpatrick, Roscoe Bartlett, Merrill Cook, Darlene Hooley, and Lynn Woolsey $20,000 each to hear testimony from a panel of researchers which included witnesses from military, agency, and political backgrounds.[115][116]
Apollo 14 astronaut Dr Edgar Mitchell claimed that he knew of senior government employees who had been involved in "close encounters" and because of this he has no doubt that aliens have visited Earth.[117]
While technically a UFO refers to any unidentified flying object, in modern popular culture the term UFO has generally become synonymous with alien spacecraft;[118] however, the term ETV (ExtraTerrestrial Vehicle) is sometimes used to separate this explanation of UFOs from totally earthbound explanations.[119]
Associated claims
Besides anecdotal visual sightings, reports sometimes include claims of other kinds of evidence, including cases studied by the military and various government agencies of different countries (such as Project Blue Book, the Condon Committee, the French GEPAN/SEPRA, and Uruguay's current Air Force study).
A comprehensive scientific review of cases where physical evidence was available was carried out by the 1998 Sturrock panel, with specific examples of many of the categories listed below.[120][121][122]
Radar contact and tracking, sometimes from multiple sites. These have included military personnel and control tower operators, simultaneous visual sightings, and aircraft intercepts. One such example were the mass sightings of large, silent, low-flying black triangles in 1989 and 1990 over Belgium, tracked by NATO radar and jet interceptors, and investigated by Belgium's military (included photographic evidence).[123] Another famous case from 1986 was the Japan Air Lines flight 1628 incident over Alaska investigated by the Federal Aviation Administration (FAA).
Photographic evidence, including still photos, movie film, and video.
Claims of physical trace of landing UFOs, including ground impressions, burned or desiccated soil, burned and broken foliage, magnetic anomalies[specify], increased radiation levels, and metallic traces. (See, e. g. Height 611 UFO incident or the 1964 Lonnie Zamora's Socorro, New Mexico encounter of the USAF Project Blue Book cases.) A well-known example from December 1980 was the USAF Rendlesham Forest incident in England. Another occurred in January 1981 in Trans-en-Provence and was investigated by GEPAN, then France's official government UFO-investigation agency. Project Blue Book head Edward J. Ruppelt described a classic 1952 CE2 case involving a patch of charred grass roots.
Physiological effects on people and animals including temporary paralysis, skin burns and rashes, corneal burns, and symptoms superficially resembling radiation poisoning, such as the Cash-Landrum incident in 1980.
Animal/cattle mutilation cases, that some feel are also part of the UFO phenomenon.
Biological effects on plants such as increased or decreased growth, germination effects on seeds, and blown-out stem nodes (usually associated with physical trace cases or crop circles)
Electromagnetic interference (EM) effects. A famous 1976 military case over Tehran, recorded in CIA and DIA classified documents, was associated with communication losses in multiple aircraft and weapons system failure in an F-4 Phantom II jet interceptor as it was about to fire a missile on one of the UFOs.[124]
Apparent remote radiation detection, some noted in FBI and CIA documents occurring over government nuclear installations at Los Alamos National Laboratory and Oak Ridge National Laboratory in 1950, also reported by Project Blue Book director Edward J. Ruppelt in his book.
Claimed artifacts of UFOs themselves, such as 1957, Ubatuba, Brazil, magnesium fragments analyzed by the Brazilian government and in the Condon Report and by others. The 1964 Lonnie Zamora incident also left metal traces, analyzed by NASA.[125][126] A more recent example involves a tear drop-shaped object recovered by Bob White and was featured in a television episode of UFO Hunters.[127]
Some ufologists recommend that observations be classified according to the features of the phenomenon or object that are reported or recorded. Typical categories include:
Saucer, toy-top, or disk-shaped "craft" without visible or audible propulsion.
Large triangular "craft" or triangular light pattern, usually reported at night.
Cigar-shaped "craft" with lighted windows (meteor fireballs are sometimes reported this way, but are very different phenomena).
Other: chevrons, (equilateral) triangles, crescent, boomerangs, spheres (usually reported to be shining, glowing at night), domes, diamonds, shapeless black masses, eggs, pyramids and cylinders, classic "lights."
Hynek's system involves dividing the sighted object by appearance, subdivided further into the type of "close encounter" (a term from which the film director Steven Spielbergderived the title of his 1977 UFO movie, Close Encounters of the Third Kind).
Jacques Vallée's system classifies UFOs into five broad types, each with from three to five subtypes that vary according to type.
One example is the response to local beliefs that "extraterrestrial beings" in UFOs were responsible for crop circles appearing in Indonesia, which the government and the National Institute of Aeronautics and Space (LAPAN) described as "man-made". Thomas Djamaluddin, research professor of astronomy and astrophysics at LAPAN stated: "We have come to agree that this 'thing' cannot be scientifically proven. Scientists have put UFOs in the category of pseudoscience.
UFOs Photographed by the International Space Station
UFOs Photographed by the International Space Station
When:April 3rd, 2018 and December 28th, 2017
Where:Space
What:Strange round objects photographed outside International Space Station
A frequent viewer of the ISS live cam witnessed a UFO on two separate occasions, and fortunately took some screenshots and shared them with MUFON (case 92258).
ok so, i have taken screenshots on my ISS app on my phone on 2 different occasions.the first was on the 28/12/17 and the 2nd occasion was on the 4/3/18. On the 28/12 i have taken 1 photo and my memory f that is a little vague. on the 4/3 i have taken 5 screenshots, all approximately 5 seconds after one another. I want to add I am using the same cell phone right now to submit this report so to submit the original photos i took with all the added info and details attached to the pictures, such as the date and time etc. and also i hope that helps to authenticate my photos are not modified at all in one way or another. I will concentrate on the 4/3 because that is more familiar in my memory. All i was doing was checking the app like i sometimes do and sometimes i see the ISS fly over my town when i am up early enough. and basically i saw the round object, and i have researched about the ISS before and know that stars and most planets are not visible through the cameras on the ISS, only the sun and moon and a not many planets. and definitely not other satellites because of the speed the ISS is traveling as well as the other satellites. i immediately begun taking screenshots and as you can see the time between the photos, i hope that will help if someone can calculate the speed of the ISS and whatever else may be to pinpoint a distance of the object and size, maybe. I have thought afterwards maybe this is just a planet or a secret human powered craft, and other ideas. but after finding this site i simply wanted to submit my info and get the experts to look at it. before the 28/12/17 i have never seen a ufo before and these are the only 2 times i have seen anything on the ISS app. i have been incredibly astonished and blown away this year to, to see a UFO with my own eyes very close to my town and i have a detailed description to tell in another report so i will just keep that brief for now.Basically i first saw the object up high then it hovered for a little while then slowly dropped downwards until it was out of sight behind earth. thank you anyone who puts time into this and can back to me if these sightings i am sharing are authentic or not. any info which i hope can be identified would be greatly appreciated. thank you
Believe it or not, sightings of UFOs by the ISS are pretty common. But is that what these photographs show - UFOs? Or do they show reflections of lights or other mundane anomalies? As always, you be the judge! Share your theories in the comments below or on Facebook, Twitter, or Instagram!
It could be a Star Trek or Star Wars universe after all. One where a diverse set of intelligent extraterrestrial species from across the galaxies all easily communicate despite some pretty dramatic biological differences.
Some of the world's leading linguists argue that human languages are connected by a shared "universal grammar." And now some, including perhaps the most well-known linguist, say they're optimistic that connection could extend to extraterrestrial languages too.
"To put it whimsically, the Martian language might not be so different from human language after all," explained Noam Chomsky and Jeffrey Watumull in a presentation at the International Space Development Conference (ISDC) in Los Angeles on Saturday.
"Chomsky has often said that if a Martian visited Earth, it would think we all speak dialects of the same language, because all terrestrial languages share a common underlying structure," said Douglas Vakoch, president of METI (short for Messaging Extra-Terrestrial Intelligence), which organized a daylong Language in the Cosmos workshop at ISDC. "But if aliens have language, would it be similar to ours? That's the big question." Linguists Bridget Samuels from the University of Southern California and Jeffrey Punske from Southern Illinois University also argued in a separate presentation at the workshop that some universal factors underlying language might be able to bridge big gaps in alien biology and environment.
"The whole universe is subject to the same laws of physics. For example, there are not that many ways a signal can be transmitted, particularly over large distances," they explained to me in an email. "Also, we can expect that extraterrestrial languages ... have a vocabulary consisting of building blocks of meaning that can be combined to create more complex meanings."
The notion here is that there are aspects of the universe that are, well, universal. While hypothetical aliens may have evolved very differently from us on very different worlds, all species -- and by extension all languages -- must spring forth from essentially the same elemental soup.
"While the possibility of human contact with extraterrestrials seems remote, and the possibility of communicating successfully with them seems even more remote, the laws of physics, information theory, logic, and mathematics could provide some common ground to start from," said Samuels and Punske.
METI is trying to work out which type of message could be most understandable to extraterrestrials. The notion that a universal grammar connecting human languages could also underlie alien dialects changes things.
"That's a radical shift for SETI scientists, who have scoffed at the idea of creating interstellar messages inspired by natural languages," said Vakoch.
In the past, messages sent into space have typically been encoded in principles of math and science rather than language. More recently, we've sent music:
Still, the notion of universal grammar applying to the whole universe is not accepted by everyone interested in the search for extraterrestrial intelligence.
Also at the workshop, Professor Emeritus Gonzalo Munevar from Lawrence Technological University presented his argument that there's more reason for pessimism when it comes to communicating with ET. He argues there are plenty of examples on Earth of different species evolving different brains that work in very different ways.
Luna moths can see ultraviolet light, some snakes can see heat and certain fish perceive electric fields, just for starters.
"An intelligent creature whose main sensory modality is electric rather than visual would have patterns of thought completely foreign to us," he explained, adding there's "no reason to expect similar scientific languages or math" to emerge on distant exoplanets.
Whether or not there's any hope that aliens could ever understand the messages we send into space, Vakoch and METI aren't about to stop trying. Beyond the obvious language barrier, Vakoch says another challenge is the time required to send and receive messages across interstellar space. A two-way conversation between Earth and the nearest planet beyond our solar system, Proxima Centauri, would require eight years just for us to send out a "hello" and receive a response.
"The greatest shift of mindset that we need to succeed in a two-way conversation with ET is to think in multigenerational terms," Vakoch said. "The scientists who start an experiment in active SETI today will probably not be around when any responses get back to Earth."

Decoding Alien Messages Could Be the Biggest Citizen-Science Project Ever
Decoding Alien Messages Could Be the Biggest Citizen-Science Project Ever
By Mike Wall, Space.com Senior Writer
Stay sharp! You may be needed to help decode a message from intelligent aliens someday.
The work of professional linguists, mathematicians and scientists "is probably not going to be enough" to unravel a cosmic mystery missive, said Sheri Wells-Jensen, a linguist at Bowling Green University in Ohio who also serves on the board of METI (Messaging Extraterrestrial Intelligence), a San Francisco-based nonprofit.
"We have to have all hands on deck," Wells-Jensen told Space.com. "We're going to need everybody, and we're going to need to generate multiple sets of meanings for a message that we get." [13 Ways to Hunt Intelligent Aliens]
An experiment performed recently by Wells-Jensen shows why we may need the power of the human hive-mind. She presented college students with several puzzles that had been coded in the manner of Lincos, a constructed language designed to be understood by intelligent extraterrestrials. The students figured out the simple stuff, such as basic mathematical functions, quite well — but things got dicey when the concepts got more complicated.
For example, Wells-Jensen gave the students the equation for the circumference of a circle, as well as a lightly coded representation of "pi" (the ratio of a circle's circumference to its diameter).
"And I said, 'OK, what is this real word?' And they came up with all kinds of crazy things," she said. "Some made poetic jumps and said, 'world'; some of them made an opposite poetic jump and said, 'infinity.' Some of them thought that I meant that the diameter of the circle ended at a wall, and said 'prison.'"
And that's for a message drawn up by a fellow human. It will doubtless be much tougher to decode something devised by creatures from a distant solar system who share no cultural or evolutionary history with us, who may rely upon different senses to perceive their environment and to communicate, and who are probably far more advanced technologically than we are.
So, we'll likely need to marshal the collective wisdom of the world, in a massive citizen-science project, to identify (and agree upon) the "right" answer, Wells-Jensen said. And our chances of success in this endeavor would be greatly increased if we all hit the books a little, to increase our critical-thinking skills and our understanding of nature and how it works, she added.
"One of the goals of METI — and I really think it should be a goal of all of us — is to work on this science-literacy problem," Wells-Jensen said.
The linguist was originally scheduled to present her results on Saturday (May 26), during a workshop at the International Space Development Conference (ISDC) 2018 in Los Angeles. But she nixed that after running out of time. Wells-Jensen has been pretty busy; she chaired the workshop, which is called "Language in the Cosmos," and she co-authored another workshop study.
The daylong workshop, which was organized by METI, explored the possibility that language — or at least certain essential elements of language — might be universal throughout the cosmos.
Famed linguist Noam "Chomsky has often said that if a Martian visited Earth, it would think we all speak dialects of the same language, because all terrestrial languages share a common underlying structure," METI President Doug Vakoch, who also presented a paper at the workshop, said in a statement. "But if aliens have language, would it be similar to ours? That's the big question."
Two workshop papers, including one co-authored by Chomsky, expressed optimism about this. Wells-Jensen said she's more skeptical, citing our lack of knowledge about the origins of human language and the difficulty of extrapolating from a sample size of one. (However, whale languages might be complex enough to boost our planet's sample to two, she added.)
"I don't think we know, but this is a nice hypothesis to play with," she said of the language-universality idea.
Humans have been trying to find out whether or not we're alone in the universe for centuries.
Aboard the Voyager 1 space probe - which has travelled further than any other man-made object - is a golden disc containing information about humans and the cultures of our planet.
It was hoped by NASA engineers in the 70s that it would once day come into contact with intelligent life and educate them about humankind.
As well as sending out potential communications to other worlds, many people have reported evidence of aliens here on Earth.
Recently, the mummified remains of what was believed to be an alien proved to be a small child.
The skeleton measured just six inches in height, and was found 15 years ago in Chile. UFO experts were convinced the mummified skeleton was extraterrestrial in origin, and a documentary suggested it was an alien.
Following five years of research, scientists concluded that the figure, nicknamed Ata, was actually a baby girl.
Even though Ata turned out to be a story of human tragedy rather than of alien visitors, there are plenty of other mysterious sightings that have yet to be explained.
Evidence of aliens on Earth - Roswell, New Mexico
In July 1947 Sheriff Jess Slaughter and Deputy Sheriff Charles Fogus were travelling together to pick up a prisoner when they heard on their police radio reports of a crashed aircraft.
The two men, who were travelling to Roswell, New Mexico, decided to investigate and stumbled across the scene of one of the most famous UFO incidents in history.
While the US military have long claimed the crashed object was merely a weather balloon, conspiracy theorists believe the site was the scene of at least one alien aircraft crash and the recovery of extraterrestrials.
In a new book, UFOs TODAY – 70 Years of Lies, Misinformation and Government Cover-Up, law enforcement officer Fogus reveals he saw a downed flying saucer and military personnel removing a number of alien bodies from the scene.
It is the first time his statement has been published.
In the interview he says he say a flying saucer crashed into the side of a river bed which was "100ft across".
Describing the scene he said: "When we got there, the land was covered with soldiers. They were hauling a big, a creature.
"The bodies must have been 5 feet tall.
"I saw the legs and feet on some of them. They looked like our feet.
"The skin was a brownish color…. Like they were in the sun too long.
"There were soldiers there….about 3 or 4 hundred of them.
"We seen them haul them (the bodies) out there, out of the canyon up to the trucks….puttin them on the tow trucks so they could haul them."
The story of the discovery at Roswell has become legend - and remained one of the most compelling conspiracy theories about the existence of alien visitors to Earth.
Evidence of aliens on Mars - trace fossils
Thanks to satellite imagery and on-site photography captured by the NASA rovers on the planet's surface, there have been many claims that aliens once inhabited Mars.
One of the most striking is the idea that fossilised remains of aliens have been preserved on the dusty surface of the red planet.
A series of pictures taken by the space agency's Curiosity rover have given rise to the idea, after researchers found what looks like fossils among the rocks.
Barry DiGregorio, a research fellow at the University of Buckingham, believes these photos (taken on January 2, 2018) reveal "trace fossils" on the surface of Mars.
"They look remarkably similar to Ordovician trace fossils I have studied and photographed here on Earth," he said.
"If not trace fossils, what other geological explanations will NASA come up with?"
NASA described the formations as "stick-like figures" with each one "about a quarter-inch long".
The space agency used the Mars Hand Lens Imager (MAHLI) camera on board the Curiosity rover to take the close-up pictures of the patterns.
Trace fossils are the name given to remains of things left behind by creatures such as dead remains, footprints or burrows.
Evidence of aliens in space - the 'Wow' signal and FSBs
Some of the biggest evidence of alien life comes through signals we intercept originating from distant corners of the galaxy.
Often, these are known as "fast radio bursts" or FSBs for short.
Back in 1977, astronomer Jerry Ehman received such a strong radio signal coming in from the heavens, he wrote the word "wow!" next to his results.
The burst of activity lasted 72 seconds and - although it came from the Sagittarius constellation - it matched no known celestial object.
But now Professor Antonio Paris from the St Petersburg College in Florida believes he's solved the mystery.
"I have always been fascinated with astronomy, space and - more importantly - whether there is life in the universe," he told the Sunday Times .
"After 40 years, the Wow signal was a cold case I wanted to reopen.
According to Professor Paris, the signal came from the hydrogen cloud created by two comets as they passed by Earth.
Using celestial records, he found that these two comets were passing by our planet on August 15, 1977 - the day the "Wow!" signal was recorded. Of course, at the time, there was no knowledge that these comets even existed.
Even without the "Wow" signal, scientists have been intercepting strange FSBs for years.
Some have been detected from an object called FRB 121102 and now a new study has found that the object is nearly 100 per cent polarised.
This polarisation suggests that the source of the bursts lies within a strong magnetic field, such as around a massive black hole - and could belong to aliens.
The findings were made by the Breakthrough Listen team at the University of California, Berkley, as well as another team of astronomers from the Netherlands.
What do most people think about aliens?
Nearly half of humans believe that intelligent extra-terrestrial life exists elsewhere in the universe, according to a study that asked 26,000 people across 24 countries.
When they were asked if they believed in the "existence of intelligent alien civilisations in the universe," 47% of the survey respondents said yes.
However, when those taking the survey were asked if they believed in "some form of life on other planets," 61% said yes.
Among those who reckon we aren't alone, 60% said we should try and communicate with aliens - something that is actually being attempted at the non profit Search for extra-terrestrial intelligence (SETI) Institute.
Martijn Lampert, research director at Glocalities , which carried out the survey, commented: "People who believe in the existence of intelligent alien civilizations are not a marginal minority, but constitute a large (47%) and distinct segment of unconventional and anti-authoritarian thinkers with a passion for science, technology, culture, politics and the arts."
Only a quarter of respondents said they didn't believe that alien life exists beyond Earth's borders.
Are aliens real?
We may not have come into contact with them yet, but it seems certain that some form of live exists beyond our planet.
Whether that live is micro bacterial or intelligent in its own right remains to be seen.
What's for sure is that human beings won't stop trying to reach out and communicate with any other species that might be listening. The truth is out there.

Three chances for humanity to find life outside the Earth
Three chances for humanity to find life outside the Earth
Since the first people sent their views to the sky, to planets, stars and galaxies outside our native world, our imagination filled the possibility of finding extraterrestrial life. However, when we approach this issue from a scientific point of view, we still do not have the first convincing confirmation of life outside the Earth. The complex, diverse forms of life that we see on Earth are the result of more than four billion years of evolution, but in space, the ingredients for life are very often. We began to find organic molecules throughout our solar system, interstellar space and even other stars. How long will it take before we receive confirmation of the existence of something living beyond the Earth? Today we search through four main methods. Which one will justify itself first – nobody knows this yet.
To have a life, you need the fundamental ingredients that are necessary for life processes: raw materials from the periodic table. To do this, it is necessary that lived and died several generations of stars that have overtaken their nuclear fuel. We found stars with solid planets at their side, which are seven billion years older than Earth and have all the elements necessary for life. We found planets of terrestrial type in potentially inhabited zones of other stars throughout the galaxy. We found organic molecules, from sugars and amino acids to ethyl formate, which gives raspberry its smell, everywhere, from asteroids and young stars to protoplanetary disks and molecular gas clouds.
In general, we believe that in our Milky Way galaxy there are more than a trillion (1012) planets, and hence chances for life. But between the planets with the ingredients and the real, good life of extraterrestrials there is a huge difference. We do not know yet whether there are any other examples of life in the universe other than those we saw on Earth. Although scientists strongly suspect that if all the same ingredients and identical laws of nature exist throughout the universe, the uniqueness of life on Earth is extremely unlikely, we have no right to draw such a conclusion without foundation. In fact, we do not even know the answer to the question: how did we come from living things to the living?
Our existence proves that this is possible. We can assume that if life appears anywhere in the universe, it can reach three different levels:
– Life begins on the planet, but can not exist, prosper or change – Life is thriving, held and preserved for billions of years, making significant changes in the properties of the surface of the world on which it lives – Life becomes intelligent, technologically advanced and either tries to communicate with the cosmos, or to subdue it, or both
Obviously, more advanced opportunities are more pleasing to us and excite the mind, but they are less likely. However, sometimes the rarest things are easiest to find, because they will stand out against the background of everything else. Here are a few different methods that we can use to search for a variety of life forms. Three chances for humanity to find life outside the Earth.
Search in the Solar System
Although life has flourished on Earth for billions of years, other worlds seem to lack such splendor. If there is life on them, it must have hung in a primitive state. Mars and Venus had a moist, warm past, like the Earth, but today Mars is cold and deserted, and Venus is poisonous and hot. The meteorites that fall to Earth contain not only the amino acids necessary for life processes, but also many other elements not related to biological processes on Earth. The moons like Europe and Enceladus have subsurface oceans with liquid water, in which there may be hydrothermal vents. At the bottom of the oceans of the Earth they are usually associated with life.
Although we have not found any evidence of the existence of living beings, past or present, on another world, the possibility of such an indescribable excitement. On Mars there are sedimentary rocks formed by the water past; will we find fossils when we dare to unearth them? On Europe and Enceladus there can be entire oceans open for research; will we find germs or something better in their waters? There is even the assumption that diatoms, examples of primitive forms of life that are found in fragments of meteorites, can have extraterrestrial origin. This is the least developed form of life from all that we can imagine, but at our disposal there are many worlds that we can physically get, visit, measure. If a primitive, simple life is everywhere, a thorough exploration of our solar system will reveal this to us.
Search on other exoplanets
Over the past 25 years, the field of exoplanetary science has given scientists a whole treasure trove of precious discoveries, thousands of planets in orbits of other stars. Many of these worlds are small, solid and are at the correct distance from their stars, which allows them to admit the presence of atmospheres and liquid water on the surface. We can not find individual microbes or fossils on them directly, because they are outside the solar system, but there are indirect methods that we could use to find life that survived and prospered: the search for changes that bring life into our atmosphere planet.
The Earth is the only known planet with such a ratio of molecular oxygen: 21% of our atmosphere is O2. Why did this happen? Life had billions of years to feed the atmosphere with its biological waste. We think that oxygen is necessary for life, but in fact, these animals evolved to use this ingredient, to find its use. As our technology improves, we will be able to measure the molecular signatures of exoplanetary atmospheres and perhaps even directly visualize exoplanets in search of clouds, oceans, seasons and continental greens. We have every reason to believe that a stable life on another planet, if we look for it correctly, should appear to us already in this century.
Search for signals of intelligent aliens
Here, on Earth, we had a unicellular life for billions of years, and then multicellular organisms developed. It took 500 million years since the Cambrian explosion, so that a complex, multicellular, well-differentiated life became a reasonable, technologically advanced civilization. People have already started sending signals to the stars and have already reached the point where these signals were to reach the nearest stars. The search for extraterrestrial life with an attempt to communicate with it is a high-risk, but at the same time, effective method of searching for aliens.
In the 1960s, we assumed that aliens would try to communicate using radio waves. It’s been 50 years, and we are not so sure about it. What alien types of signals can exist in nature? How do we decrypt them? How will they transmit or receive interstellar signals? Will they conquer outer space? Will they be able to overcome giant distances? Everything is possible. If the signal – or, better yet, the spacecraft – will fly to Earth, our view of the universe will completely change, just like our place in this universe.
Although at the moment this is just a hypothesis, scientists suggest that life in the universe is probably widespread, and the ingredients and opportunities for its emergence are found almost everywhere. Life that thrives and sustains itself on the planet, and also changes the atmospheric composition, will be less likely. Complex multicellular life will be even more rare. And the birth of a technologically advanced, intelligent civilization will be so incredible that it will not have a second chance. However, whatever the odds, we will continue to look. We do not have many options yet. And no matter which method shoots first, the day of the discovery of another life will be the greatest day in the history of life on Earth.
Who Or How Were Earth’s Ancient Structures Built? Ancient Aliens or Forgotten Technology? … Or Both?
Who Or How Were Earth’s Ancient Structures Built? Ancient Aliens or Forgotten Technology? … Or Both?
Exactly how were the great pyramids in Egypt and Mexico built?
How were the famous Inca & Mayan stones squashed into each other?
How was the great stones of Stonehenge placed high on top of each other?
These questions and many more have fascinated people for centuries. Not only are they structures which were built during periods where technology was supposed to be very basic but the more we learn about them the more they baffle us.
For example, the Sphinx and the Pyramids in Egypt are thought to be older than what we are being told. Geologists say that weathering patterns on the Sphinx show rain damage which puts the building date of the Sphinx well past the date of the Egyptians we are lead to believe were responsible for building it.
The pyramids themselves hold many mysteries, much of it appears as scientific code. The layout of the pyramids in Giza are an exact copy of the stars in the Orion’s Belt constellation. Spread out over miles of Egypt’s land the smaller pyramids also line up with the stars of the same constellation. Is Egypt a star map of where our ancestors came from?
More interesting is the coordinates of the pyramids at Giza in Egypt . Their coordinates are 29.9792458 degrees North and what is the speed of light in a vacuum? 299.792,458 metres per second. Coincidence or planned as a message to modern man?
However it should be mentioned that modern latitude is set so that the prime meridian goes through Greenwich England which did not exist at the time the pyramids were built so whatever system they would have used would not have been this one… unless… they were time travellers and knew what system would be in place several thousand years later. Now that would blow the socks of modern man if that were true!
The pyramids are also mentioned on an ancient Sumerian tablet. The Sumerians were in Egypt thousands of years before the ancient Egyptians who are believed to be responsible for building them. This ages them thousands of years more than what is publicly believed.
The Great pyramid hasn’t dropped more than a feet yet the weight of the structure is immense. Modern skyscrapers are designed to drop more once built. The blocks of stone that the pyramids are made from are huge and weigh so much that even modern cranes would struggle to move them. As far as we know there were no modern cranes around.
So how were they built? How were the big stones of Stonehenge lifted? Were there aliens involved in the construction? Was alien technology used? Was there an Atlantis type super race of ancient humans building these structures or did basic man know more about physics than we believe.
The Mayans, Egyptians and Incas are all supposed to have cosmology knowledge and understanding which far surpassed that of which we believe they should have so did they have a better understanding of quantum physics and the little known vibrational physics than we first thought?
The reason I say vibrational physics is that there is a story of a Swedish dr who went to Tibet in 1939 to visit the Dalai Lama. It is said that while he was there the monks were building a high wall using heavy stones. The story goes that he observed the monks lifting up the heavy stones by levitating them using sound.
The monks set up drums and horns in an arc shape a certain distance away from the stones and then began to make sounds which lifted up the heavy stones and they were then pushed into place. Meditation and Eastern philosophies put a lot of emphasis on sound. Especially the Ohm sound which is the Universal vibration rate sound.
Did our forefathers know something that we are just beginning to understand? Was this kept a secret from us?
The Swedish doctor apparently recorded this on film but the film was confiscated from him by British authorities and never seen again. Funny that?
We know about the law of attraction, things which vibrate with the same or similar frequency are drawn to each other like magnets. We have seen what some metals do when they are near magnets but everything has a vibration and a specific rate so that means that everything can be lifted up like a magnet if you hit the right frequency.
Acoustic Levitation in Egypt – Ancient High Technology
Alien abductees talk about being lifted up out of houses. Do aliens know something about acoustic levitation or vibrational physics? Did they give that knowledge to us years ago and has been kept secret by those in the know or did ancient man know about it but it somehow got forgotten about? Maybe it was lost when modern style governments were formed and knew that there would be no profit or tax in construction if everyone had access to this knowledge.
If you are not sure whether you have been abducted by aliens then use this checklist here to find out:
Another puzzling ancient mystery is the stone walls in south and central America. They have been cut and shaped to fit so tight and snug that even to this day people cannot slide pieces of paper between them.
They are also oddly shaped which is interesting. What people do not know is that how they were carved and made. There have been stories and theories that say that the Ancient Mayan and Incan builders were able to soften the stones and mold them into position.
Megalithic Softening of Stone Part 1
A very old story spoke about how an explorer discovered that a mixture made from plants which were found in central America would somehow soften the stone which was then pushed and molded into shape. How true this is no one knows.
What is interesting is that there are very little scratch and tooling marks to see. We do have thousands of years of weathering so the smallest marks might have been eroded but the stone work across central and south America is pretty impressive.
Maybe the stone was an ancient version of concrete and were molded and fashioned into shapes. This is another theory being put forward today.
What do you think? Were our ancestors smarter than we give them credit for using technology we no longer use or were these impressive structures built by or with the help of Ancient Aliens?

A lot can happen in a second; you could meet a stranger, snap your fingers, fall in love, fall asleep, sneeze. But what is a second, really — and is it as precise as we think it is?
Right now, the most-precise clocks used to tell global time have an error of about 1 second every 300 million years — so a clock that started ticking in the time of the dinosaurs wouldn't be off by even a second today. But scientists think we can do better. [The 18 Biggest Unsolved Mysteries in Physics]
So, they are looking to lutetium, a neglected rare-earth element that has been gathering dust at the bottom of the periodic table, according to a new study published April 25 in the journal Nature Communications.
Why is one second 1 second long?
In the olden days, a second was defined as a fraction (1/86400) of the average solar day, the 24-hour rotation of the Earth around its axis. But the rotation of the Earth can vary slightly, so scientists decided to stop scanning the heavens to calibrate our clocks and scaled things way down — to the level of atoms, the invisible building blocks of matter.
In 1967, the International Committee for Weights and Measures defined the second as the amount of time it takes for a cesium atom to absorb enough energy to be excited — that is, for its electrons to jump from one energy state to the next. For this to happen, the atom must be pulsed with exactly 9,192,631,770 cycles of microwave radiation.
Though that number might seem random, it comes from measuring the frequency of microwaves needed to excite the cesium atoms in the average of the earlier definition of 1 second. These measurements were taken over a span of nearly three years, Scientific American reported.
Currently, hundreds of cesium atomic clocks are responsible for keeping global time and controlling GPS navigation. But in the past decade, another generation of atomic clocks has emerged, called "optical clocks," and they are 100 times more precise than the cesium variety. The new clocks work in the exact same way as the cesium ones, except they use atoms such as aluminum or ytterbium that get excited by higher frequencies of visible light (hence the name "optical") rather than the slower microwaves. This higher frequency adds more data points to the definition of a "second," making the measurement more precise. [7 Strange Facts About Quarks]
To understand this, imagine the different types of clocks as a pair of rulers, said Murray Barrett, an associate physics professor at the National University of Singapore and the lead author of the new study. If the older, "cesium" ruler measures a line that's 20 centimeters (7.9 inches) long, the more precise, "optical" ruler can measure the line also as, for example, 200 millimeters.
While optical clocks are very precise , getting them to run for a very long period of time and to remain stable in their environments can be problematic, Barrett said. A room's temperature can change the electromagnetic fields acting on the atoms, which in turn can skew the time measurement, Barrett said. So, the cesium clocks are still "much more reliable in their implementation than [the new] optical clocks," Barrett told Live Science.
Making less sensitive atomic clocks
In their new study, Barrett and his team found that a lutetium ion is less sensitive to changes in environmental temperature than are any other elements used for optical clocks, making it a strong candidate to serve as master time keeper.
Lutetium atoms can also help compensate for another problem affecting time measurement, the team found. Because the atoms used in these clocks are charged, they slightly wiggle back and forth in response to the electromagnetic fields created by the waves (visible light, microwaves, etc.) — and this can skew the time measurement. Scientists call this rapid backward and forward movement a "micromotion shift."
Because scientists must compensate for this shift, it's really difficult to develop atomic clocks with more than one ion — which would make such clocks more practical, Barrett said. But the team found that they could use a natural property in a certain type of lutetium ion to cancel out these "micromotion shifts."
However, this comes at a cost: Those atoms became more sensitive to the temperature of the room. That trade-off might limit the impact of the new finding, and the atom lutetium might not be a "real game changer," said Jérôme Lodewyck, a physicist at the Paris Observatory who was not part of the study.
But, this "high-quality work" adds another possible atomic species to the long list of timekeeper candidates that is a "wealth for metrologists" looking to compare different clocks, Lodewyck said. [What's That? Your Physics Questions Answered]
Beyond telling time
Though Barrett said lutetium "is extremely promising," he doesn't think there's a big rush to redefine the second using optical clocks, as cesium clocks do just fine at things like getting us where we need to go.
But highly precise optical clocks might allow for new applications "that would simply not be possible with our current technology," Barrett said.
For example, clocks are sensitive to where they sit in the world, because time is distorted by gravity, according to Albert Einstein's theory of general relativity. Right now, atomic clocks on Earth can't detect the miniscule time-warping that occurs due to Earth's gravity. But if researchers could place highly precise optical clocks around the world, that setup could help researchers map out the gravitational field of our planet, Barrett said.
Further, highly precise atomic clocks could detect matter and energy we may not yet be able to see, Lodewyck said. That could include dark matter, which exerts a gravitational pull yet does not interact with ordinary light, and dark energy, the mysterious force that seems to be accelerating the expansion of the universe, he said.
Here's how it might work: If you know the frequency needed to excite some atoms in the time frame of a second, you could use these various clocks around the world to detect any differences beyond what you would normally expect. There are "some theories that say dark matter is around us, so if we cross a chunk of dark matter, this would perturb the clock," Lodewyck told Live Science.
There may even be applications we can't think of right now, Barrett said. "Certainly, when we first started developing clocks for the purpose of ship navigation, we never imagined the idea of somebody being able to walk around and know exactly where they are in a big city."

VIDEO. Alan Bean, le quatrième homme à avoir marché sur la Lune, est mort
DECES Il a effectué deux missions dans l'espace, dont Apollo 12 en 1969...
Il avait été précédé par Neil Amstrong, Buzz Aldrin et Pete Conrad. L’astronaute Alan Bean, le quatrième homme à avoir marché sur la Lune, est mort samedi dans le sud des Etats-Unis après être brusquement tombé malade quelques semaines auparavant, a annoncé sa famille dans un communiqué diffusé par la Nasa.
NASA✔@NASA
We remember Apollo 12 astronaut Alan Bean, who walked on the Moon in 1969, commanded the second Skylab crew in 1973 and went on in retirement to paint the remarkable worlds and sights he had seen like no other artist.
Cet ancien pilote d’essai dans la Marine américaine, devenu peintre après avoir quitté en 1981, pour prendre sa retraite, l’agence spatiale américaine, s’est éteint à Houston, au Texas, à l’âge de 86 ans (il est né le 15 mars 1932 à Wheeler, également au Texas).
« Tout artiste a la Terre, et je suis le premier à avoir aussi la Lune »
Alan Bean s’est aventuré pour la première fois dans l’espace en 1969 pour la mission Apollo 12, à l’occasion de laquelle il a marché sur la Lune. Quatre ans plus tard, il est retourné dans l’espace en tant que commandant du deuxième équipage à se rendre à bord de Skylab, la première station spatiale américaine. C’est alors qu’il établit un nouveau record pour l’époque de durée de vol hors de l’atmosphère, avec plus de 59 jours et 24.400.000 milles (39.268.000 km).
Alan Bean est mort. Il a marché sur la Lune dès son 1er vol, puis a volé sur Skylab avant d'être connu pour ses peintures spatiales. C'était un des rares à avoir parlé de la peur qu'il a pu ressentir dans l'espace. Bon voyage. Il ne reste que 4 "moonwalkers" encore vivant...
« Tout artiste a la Terre ou son imagination pour inspirer ses peintures », avait expliqué en 1994 au New York Times celui qui s’était mis à reprendre dans ses œuvres des thèmes liés à la conquête spatiale. Avant d’ajouter : « J’ai la Terre et mon imagination, et je suis le premier à avoir aussi la Lune ».
NOT LIKE THE OTHERS Many asteroids share Jupiter’s orbit (illustrated, not to scale). Most asteroids travel in the same direction around the sun as the planet. But there’s one moving in reverse, which could indicate it came from outside the solar system.
JPL-CALTECH/NASA
An asteroid that flouts the norms of the solar system might not be from around here.
The renegade asteroid travels around the sun in reverse — in the opposite direction of the planets and most other asteroids (SN: 5/13/17, p. 5). Now two scientists suggest that’s because the space rock originated from outside the solar system, according to a paper published May 21 in Monthly Notices of the Royal Astronomical Society Letters.
Astronomers Fathi Namouni of the Côte d’Azur Observatory in Nice, France, and Helena Morais of Universidade Estadual Paulista in Rio Claro, Brazil, used computer simulations to show that the asteroid, which shares its orbit with Jupiter, could have been traveling in reverse ever since the solar system’s youth. Because asteroids in the infant solar system formed from one swirling cloud, they should have all been traveling in the same direction. So the best explanation, the duo suggests, is that the rock, known as 2015 BZ509, migrated here from another star’s planetary system.
ON THE MOVE The asteroid 2015 BZ509 (circled), which orbits the sun in reverse, is shown surrounded by stars (larger black spots) in two sets of images taken by the Large Binocular Telescope near Safford, Ariz.
C. VEILLET/LARGE BINOCULAR TELESCOPE OBSERVATORY
In 2017 astronomers spotted the first interstellar asteroid, dubbed ‘Oumuamua, which cruised through the solar system and back out again (SN Online: 12/1/17). Asteroid 2015 BZ509, however, appears to be a long-term inhabitant.
“It’s certainly an interesting possibility,” says astronomer Martin Connors of Athabasca University in Canada. But, he says, the study doesn’t nail down whether the asteroid actually came from outside the solar system.
Such asteroids are faint and hard to get information from, Connors says. “There isn’t really a blazing sign saying, ‘Hey, I’m not from here.’ ”
A new study concludes that a large, as-yet-unknown Planet Nine – an estimated 4 times the size of Earth and 10 times its mass – is influencing the behavior of an oddball object in the outer solar system.
Diagram depicting the orbit of 2015 BP519 (Caju), which has the highest inclination of any extreme trans-Neptunian object discovered to date. Its unusual perpendicular orbit may be evidence for Planet Nine.
Is there a ninth major planet lurking in the outer reaches of our solar system? This question has become one of the most hotly debated in planetary science. The idea of a large, unknown Planet Nine residing so far from the sun that it hasn’t yet been discovered is certainly tantalizing. So far, there’ve been hints as to its existence, but no confirmation yet. We might be getting closer to finding it, however. Last week, an international team of researchers presented additional evidence, detailed in a new study, suggesting that Planet Nine is influencing the behavior of an oddball object – 2015 BP519 (aka Caju) – in the outer solar system.
Astronomers at Caltech had previously calculated the likely existence of a large ninth planet (sorry, Pluto) in the outer fringes of the solar system, based on the orbits of smaller icy objects. Their orbits were being perturbed by the gravitational influence of … something.
According to the astronomers’ calculations, the as-yet-undiscovered planet should be about four times the size of Earth and 10 times its mass. That would make it similar to super-Earth exoplanets found orbiting other stars. And that would be interesting, since many super-Earths have now been discovered, although there were none to be seen in our own solar system. But maybe there is one after all, so far from the sun that it has remained hidden.
Such a discovery would be very exciting, since super-Earths are larger than Earth but smaller than Uranus or Neptune, different from anything else in our solar system. If a large Planet Nine is there, it is very far away, much farther than Pluto. If it exists, it likely takes about 10,000 to 20,000 years to complete one orbit around the sun.
Planet Nine may be a super-Earth, a type of exoplanet found orbiting many stars. They are rocky and larger than Earth, but smaller than Uranus or Neptune.

Astronomers first discovered 2015 BP519 (Caju) three years ago. It is a trans-Neptunian object (TNO), which, generally speaking, are minor planets orbiting the sun beyond the orbit of Neptune. Caju is one of only a dozen or so known objects that are categorized as extreme trans-Neptunian objects (ETNOs). Such objects have a semi-major axis greater than 150 astronomical units (AU) and a perihelion – closest point to the sun – greater than 30 AU. Caju’s estimated diameter is 248-434 miles (400-700 km), making it a potential dwarf planet. So it is a very interesting object.
What’s more, since its discovery, further analysis has shown that Caju has an unusual orbit, which lies almost perpendicular to all the known planets. In fact, Caju has the highest inclination of any TNO discovered so far.
Amazingly, just such an object had been predicted by computer models performed by the team searching for Planet Nine. Caltech astronomer Mike Brown, who wasn’t part of the new study, but who is active in Planet Nine research, told PopSci.com on May 22, 2018:
I’m pretty excited about the new object. It is the predicted link between the very distant elongated orbits that we’ve known about and the much closer tilted orbits that we’ve seen.
Thus Caju adds to a growing body of evidence for the elusive Planet Nine, which – if really there – still remains out of sight for astronomers. Astronomer Konstantin Batygin – who, along with Brown, first gave Planet Nine a name, size and distance – told Space.com on May 21 that, as of October 2017, there were at least five lines of evidence pointing to Planet Nine’s existence. Earlier, in 2017, astronomers had found evidence that 22 other TNOs seemed to have their orbits perturbed by another large unseen planet. Batygin said:
If you were to remove this explanation and imagine Planet Nine does not exist, then you generate more problems than you solve. All of a sudden, you have five different puzzles, and you must come up with five different theories to explain them.

Bottom line: While Planet Nine still hasn’t been confirmed, the evidence is growing that just maybe, an as-yet-unseen large planet does indeed prowl the desolate outer fringes of our solar system.
US Intelligence Indirectly Confirms Existence of Russia's Hypersonic Weapons
US Intelligence Indirectly Confirms Existence of Russia's Hypersonic Weapons
Sources with direct knowledge of US intelligence reports say Russia is on the brink of developing a maneuverable, hypersonic nuclear-capable glider warhead that no US system can defeat.
The sources, speaking to CNBC on condition of anonymity, reported that Russia tested a nuclear-capable hypersonic glide vehicle (presumably the Avangard) twice in 2016, and again in 2017. The 2017 test was a failure, according to the sources. A fourth test is expected sometime this summer.
Citing an intelligence report, a source said the hypersonic glider's testing involved mounting it to an RS-18A intercontinental ballistic missile (NATO reporting name SS-19).
US intelligence says the vehicle is highly maneuverable, and thus unpredictable and hard to track. It is also fitted with onboard countermeasures, which no existing US missile-defense system can defeat. Furthermore, although it can carry a warhead, it is believed that the force of the glider's impact, as well as its precision, may be enough to destroy targets.
The intelligence reports, allegedly created this past spring, calculate that the Avangard will likely be operational by 2020, according to CNBC's sources.
The news site doesn't specify whether the reports were released before or after President Putin's unveiling of of cutting-edge new Russian missile systems in a speech to lawmakers on March 1. Putin confirmed the existence of a hypersonic glider, dubbed the Avangard, as well as the Kinzhal air-launched hypersonic missile, an unnamed nuclear-powered cruise missile, and an unnamed sub-launched nuclear-powered submersible drone.
Putin said these systems, which are nearly operational, were aimed at guaranteeing Russian security amid the US withdrawal from the ABM Treaty, and NATO's continual expansion along Russia's western borders. The Kinzhal hypersonic missile appeared at the 2018 Victory Day parade in Moscow.
In late March, Strategic Command commander Gen. John Hyten told Congress that there was nothing in the Pentagon's arsenal capable of stopping Russia's new hypersonic weapons. Hyten confirmed that the United States was watching both Russia and China's hypersonic capabilities closely.
On Tuesday, President Putin confirmed that 14 missile regiments would receive the new Yars ICBM system to replace the Topol before the end of the year. The Aerospace Forces will also get upgraded Tu-95MS and Tu-160 missile-carrying bombers armed with Kh-101 and Kh-102 long-range conventional and nuclear missiles, according to the president. Putin also urged the defense sector to prepare for the manufacture of the new S-500 anti-ballistic missile system, assumed to be capable of intercepting targets, including satellites, in near space. The new equipment is set to arrive despite a 20 percent cut in Russia's defense spending between 2016 and 2017, from about $65.4 billion, to about $48 billion per year.
The US is engaged in its own military modernization, with nuclear modernization alone expected to cost some $1.2 trillion through to 2046. President Trump proposed increasing the 2019 fiscal year budget to $681.1 billion.
Zealous Ufologist Says Extraterrestrials are Sabotaging Nukes to Stop Apocalypse
Zealous Ufologist Says Extraterrestrials are Sabotaging Nukes to Stop Apocalypse
Conspiracy theorists have long suspected that the world’s governments are managing secret extraterrestrial projects, and last December’s report on the Pentagon’s black budget study of UFOs fanned the flames of conspiracy.
A ufologist, who preferred to remain anonymous, took to the website Alien Revelations to claim that aliens are seeking to stop humans from using nuclear weapons, “because we simply cannot be trusted with such massive power.”
The author recalled former US Air Force Lieutenant Bob Jacobs’ interview on the Larry King show a few years ago when he claimed that his superiors had warned him to remain silent about having seen a UFO at the Vandenberg Air Force Base.
His seniors, however, were not as excited about the alleged sighting of an unidentified flying object, saying “this didn’t happen,” but many ufologists say UFO encounters often occur around nuclear bases.
According to another website, Collective-Evolution, a similar incident happened at the Malmstrom Air Force Base.
“This occurred in March of 1967 at a base that was responsible for a large amount of nuclear weapons. Witnesses here saw a red, glowing UFO hovering just outside the front gate. After that happened, all of the nuclear missiles shut down, and went completely dead.”
The ufologist said it wouldn’t be “surprising” if extraterrestrials were trying to prevent the apocalypse by creating obstacles for human nuclear experiments.
“We observed the UFOs were very interested in the nuclear weapons manufacturing facilities. A couple of nuclear weapons that were sent out into space were destroyed by the extraterrestrials. At the very end of the 70s and early 80s, we attempted to put a nuclear weapon on the moon and explode it for scientific measurements. They destroyed the weapon before it got to the moon.”
Despite all theories, NASA has always denied the existence of alien life.
“The only life we know about is on Earth. NASA is always looking for life out there, and when we find it, we will tell you,” Paul Hertz, Astrophysics Division at NASA Headquarters in Washington, stated last year.

Een ufoloog heeft nu op de website Alien Revelations geclaimd dat aliens proberen te voorkomen dat mensen kernwapens gebruiken, schrijft persbureau Sputnik.
De auteur verwees naar een interview met luchtmachtluitenant Bob Jacobs tijdens de show van Larry King enkele jaren geleden waarin hij zei dat hij van zijn bazen opdracht had gekregen om zijn mond te houden over een UFO die hij had gezien vanaf vliegbasis Vandenberg.
Uitgeschakeld
“Dit is nooit gebeurd,” zeiden ze, maar volgens veel ufologen worden er vaak UFO’s waargenomen in de buurt van kernbases.
De website Collective Evolution verwijst naar een incident op Malmstrom Air Force Base, waar in maart 1967 een rode UFO boven de ingang verscheen.
Kort daarop werden alle kernkoppen uitgeschakeld en waren ze niet meer inzetbaar, verklaarde officier Robert Salas, die op dat moment op de basis was gestationeerd.
Apocalyps
De ufoloog zei dat hij niet verbaasd zou zijn als bleek dat buitenaardsen de apocalyps proberen te voorkomen door mensen ervan te weerhouden kernwapens in te zetten.
“De UFO’s waren zeer geïnteresseerd in plekken waar kernwapens werden gemaakt,” klonk het. “Kernwapens die de ruimte zijn ingeschoten, zijn vernietigd door buitenaardsen.”
Maan
“In de jaren zeven en tachtig probeerden we een kernproef te doen op de maan,” vervolgde hij. “Ze vernietigden het wapen voordat het de maan kon bereiken.”
NASA heeft het bestaan van buitenaards leven altijd ontkend.
One of the biggest stories in UFO research over the last year has been the revelation that the Pentagon has recently been funding recent research in anomalous aerial phenomena to the tune of $22 million a year. Claims of government involvement in UFO research are nothing new in ufology circles, but the scope of the publicly-acknowledged program and the accompanying allegedly declassified videos of military vehicles tracking strange, incredibly agile objects in the sky were enough to make some skeptics wonder if indeed the government might know a lot more about unidentified aerial phenomena than they let on.
The U.S. government’s interest might not just stop at aerial phenomena, however. A new trove of documents obtained by KLAS-TV in Las Vegas seem to reveal that the Defense Intelligence Agency (DIA) has conducted extensive research in fringe science, touching upon phenomena usually only discussed in paranormal circles. The report, titled “Warp Drive, Dark Energy, and the Manipulation of Extra Dimensions,” seems to indicate that the defense industry might indeed have a keen interest in the higher mysterious of our physical reality itself. Does their interest stop at theoretical research, or could the U.S. military actually be manipulating the fabric of space time?
Probably not yet, especially given recent tests of the supposed EM Drive warp engine. The report does seem to suggest that the DIA’s interest in these topics all center around the explore reach far corners of interstellar space:
The idea that а sufficiently advanced technology may interact with, and acquire direct control over, the higher dimensions is а tantalizing possibility, and one that is most certainly worthy of deeper iпvestigation. Control of this higher dimeпsional space may bе а source of technological control оvег the dark energy density and could ultimately play а role in the development of exotic pгopulsion technologies; specifically, а warp drive.
Exactly why the DIA is interested in space travel is unknown. The report ultimately doesn’t reveal any black budget secret research projects into space-time-bending technologies, but does suggest that the military-industrial complex is tantalized by several current developments in quantum physics:
Of course, this may not bе actualized until many years in the future, but consider the many spectacular physical phenomena that are believed to bе true at this early point in the 21st century. One also believes that the universe may not consist of the three spatial dimension of length, breadth, width, and one of time, but that, in fact, there mау bе as many as seven additional compactified dimensions assuming the topology of а Calabi-Yau manifold, апd that the fundamental building blocks of the universe are, in fact, extended string-like entities.
In science fiction, it’s often the military who accidentally opens a dimensional rift in an attempt to travel to a far away star system, allowing untold horrors to pour through into our plane. Does this report such an incident might be in our near future? While it might sound fantastic, the report concludes with the sentiment that “it seems entirely possible that the creative minds of the future may indeed find ways to accomplish what, to us, may seem like magic.” Make your peace with the Great Old Ones now before it’s too late.

Just recently I wrote an article titled “A factual object of very unusual nature.” It served to demonstrate that, contrary to what some have said, the U.S. Freedom of Information Act has led to the release of genuinely intriguing UFO reports. It’s certainly not the case that all the “good” reports remain hidden behind closed doors. Yes, many probably do remain classified. But, that does not take away the fact that there are some fascinating, once-classified, files on UFOs in the public domain. Today, I’m focusing on some of the files that the British Government declassified back in the 1980s. They too demonstrate – to an amazing degree – that at times government agencies are prepared to reveal to us accounts of a very extraordinary type.
In September 1952, a notable UFO encounter occurred at Royal Air Force Topcliffe, a military base in Yorkshire, England. One of the witnesses, Flight Lieutenant John Kilburn, said of the incident: “Sir, I have the honor to report the following incident which I witnessed on Friday, 19th September, 1952. I was standing with four other aircrew personnel of No. 269 Squadron watching a Meteor fighter gradually descending. The Meteor was at approximately 5000 feet and approaching from the east. [Flight Officer R.N.] Paris suddenly noticed a white object in the sky at a height between ten and twenty thousand feet some five miles astern of the Meteor.”
Raptors
“The object was silver in color and circular in shape, it appeared to be traveling at a much slower speed than the Meteor but was on a similar course. It maintained the slow forward speed for a few seconds before commencing to descend, swinging in a pendular motion during descent similar to a falling sycamore leaf…After a few seconds, the object stopped its pendulous motion and its descent and began to rotate about its own axis.
“Suddenly it accelerated at an incredible speed towards the west turning onto a south-easterly heading before disappearing. All this occurred in a matter of fifteen to twenty seconds. The movements of the object were not identifiable with anything I have seen in the air and the rate of acceleration was unbelievable.”
Five years later, specifically on March 26, 1957, there was yet another amazing encounter. And again the U.K. Government handed over the files to ufologists – and with not a hassle in sight. The document states in part: “A report was received from Royal Air Force Church Lawford on 26th March, 1957 of a sighting of an unusual nature. The object moved at a speed timed at exceeding 1400mph. This in itself was unusual as the object had accelerated to this speed from a stationary position. No explanation has yet been found for this sighting but a supplementary report, including a copy of the radar plot, was requested and has been received from Church Lawford this afternoon.”
A little more than a week later, there was yet another incredible encounter. April 4, 1957 was the date on which an extraordinary wave of UFO activity occurred in Scotland, much of it involving the staff of a military facility called Royal Air Force West Freugh. Nothing less than a squadron of huge, unknown aircraft were recorded flying in the U.K.’s airspace. The Air Ministry ruled out a convention explanation. Instead, as the now-declassified files show, the Air Ministry was of the opinion that…
Typhoon FGR4
“It is deduced from these reports that altogether five objects were detected by the three radars. Nothing can be said of physical construction except that they must have been either of considerable size or else constructed to be especially good reflectors. There were not known to be any aircraft in the vicinity nor were there any meteorological balloons. Even if balloons had been in the area these would not account for the sudden change of direction and the movement at high speed against the prevailing wind.The incident was due to the presence of five reflecting objects of unknown type and origin. It is considered unlikely that they were conventional aircraft, meteorological balloons or charged clouds.”
Of course, this is an extraordinary revelation. And when the files were declassified back in the late 1980s, more than a few U.K. ufologists were surprised by the government’s decision to release them, particularly given the fact that their content practically screamed out that UFOs were real.
If anyone ever tells you that governments always hold back all the “good stuff,” you can tell them they’re wrong.
Skywatcher Films Rare Red Sprites In The Sky Above Oklahoma
Skywatcher Films Rare Red Sprites In The Sky Above Oklahoma
Paul Smith captured images of a rare sky phenomenon called red sprites in Oklahoma, on May 24, 2018 and states: "Lots of TLEs from Oklahoma tonight and his one stands out as my best to date. 12.55am/6:55 UTC 5/24/2018 looking WNW from north Edmond, Oklahoma. It even has the blue/purple ends on the tendrils."

Paul finds it very curious that TLEs were only first documented relatively recently - red sprites in particular, once considered rare, are now being recorded with increasing regularity.
And as storms passed by to the NW, Paul recorded another sprite lightning event up close in all it's glory. The clip really illustrates the electrical connection of the phenomena- how it flickers looks very electrical in nature to me. First is real time then slowed down 10 times.

'TLE' stands for Transient Luminous Event, which includes upper-atmosphere electric phenomena known as sprites, jets and ELVES. These high-altitude discharges were once considered to 'possibly occur' because pilots reported seeing them, but meteorologists discounted the idea until 1989 when the first visual documentation was made in support of the claims.
Clearly, great changes are occurring on our planet. And not just on our planet.

Vesta is the second most massive body in the asteroid belt, surpassed only by Ceres, which is classified as a dwarf planet. The brightest asteroid in the sky, Vesta is occasionally visible from Earth with the naked eye. It is the first asteroid to be visited by a spacecraft. The Dawn mission orbited Vesta in 2011, providing new insights into this rocky world.
Celestial Police
In 1596, while determining the elliptical shape of planetary orbits, Johannes Kepler came to believe that a planet should exist in the gap between Mars and Jupiter. Mathematical calculations by Johann Daniel Titius and Johann Elert Bode in 1772 — later known as the Titius-Bode law — seemed to support this prediction. In August 1798, a group known as the Celestial Police formed to search for this missing planet. Among these was German astronomer Heinrich Olbers. Olbers discovered the second known asteroid, Pallas. In a letter to a fellow astronomer, he put forth the first theory of asteroid origin. He wrote, "Could it be that Ceres and Pallas are just a pair of fragments … of a once greater planet which at one time occupied its proper place between Mars and Jupiter?"
Olbers reasoned that the fragments of such a planet would intersect at the point of the explosion, and again in the orbit directly opposite. He observed these two areas nightly, and on March 29, 1807, discovered Vesta, becoming the first person to discover two asteroids. After measuring several nights' worth of observations, Olbers sent his calculations to mathematician Carl Friedrich Gauss, who remarkably computed the orbit of Pallas in only 10 hours. As such, he was given the honor of naming the new body. He chose the name Vesta, goddess of the hearth, and sister to Ceres. [Photos: Asteroid Vesta and NASA's Dawn Spacecraft]
Physical characteristics of Vesta
Vesta is unique among asteroids in that it has light and dark patches on the surface, much like the moon. Ground-based observations determined that the asteroid has basaltic regions, meaning that lava once flowed across its surface. It has an irregular shape, roughly that of an oblate spheroid (in nontechnical terms, a somewhat smooshed sphere).
Diameter: 329 miles (530 kilometers)
Mass: 5.886 X 1020 lbs. (2.67 x 1020 kilograms)
Temperature: 85 to 255 K (minus 306 to 0 degrees Fahrenheit / minus 188 to minus 18 degrees Celsius)
Albedo: 0.4322
Rotation period: 5.342 hours
Orbital period: 3.63 years
Eccentricity: .0886
Aphelion: 2.57 AU
Perihelion: 2.15 AU
Closest approach to Earth: 1.14 AU
Surface, composition and formation
When Vesta made a close approach to Earth in 1996, the Hubble Space Telescope mapped its topographic surface and features. This revealed a large crater at the south pole that slices into its interior. The crater averages 460 km in diameter — remember: Vesta itself is only 530 km across. It cuts an average of 13 km into the crust, and most likely formed from an impact in the asteroid's early life. The material ejected from this collision resulted in a number of smaller — Vestoid — asteroids that orbit near their parent, as well as some of the meteorites that have crashed into Earth.
Unlike most asteroids, the interior of Vesta is differentiated. Like the terrestrial planets, the asteroid has a crust of cooled lava covering a rocky mantle and an iron and nickel core. This lends credence to the argument for naming Vesta as a protoplanet, rather than as an asteroid.
Vesta's core accreted rapidly within the first 10 million years after the formation of the solar system. The basaltic crust of Vesta also formed quickly, over the course of a few million years. Volcanic eruptions on the surface stemmed from the mantle, lasting anywhere from 8 to 60 hours. The lava flows themselves ranged from a few hundred meters to several kilometers, with a thickness between 5 to 20 meters. The lava itself cooled rapidly, only to be buried again by more lava until the crust was complete. Dawn's gravity put its core at about 18 percent of Vesta's mass, or proportionally about two-thirds as massive as Earth's core.
In fact, if it weren't for Jupiter, Vesta could have had a good chance at becoming a planet.
"In the asteroid belt, Jupiter basically stirred things up so much that they weren't able to easily accrete with one another," Dawn scientist David O'Brien, of the Planetary Science Institute in Tucson, Arizona, told reporters in 2012.
"The velocities in the asteroid belt were really high, and the higher the velocity is, the harder it is for things to merge together under their own gravity," O'Brien added.
In 1960, a fireball streaking through the sky over Millbillillie, Australia, announced the arrival of a piece of Vesta on Earth. Composed almost entirely of pyroxene, a mineral found in lava flows, the meteorite bears the same spectral signals as Vesta.
NASA's Dawn spacecraft, which visited the asteroid in 2012, discovered that the rocky body had a surprising amount of hydrogen on its surface. It also found bright, reflective regions that may have been left over from its birth.
"Our analysis finds this bright material originates from Vesta and has undergone little change since the formation of Vesta over 4 billion years ago," said Jian-Yang Li, a Dawn participating scientist at the University of Maryland, College Park, in a statement.
A massive mountain towers over Vesta's southern pole. The enormous mountain reaches up over 65,000 feet (20 kilometers) in height, making it nearly as tall as Olympus Mons, the largest mountain (and volcano) in the solar system. Olympus Mons soars about 15 miles (24 kilometers) above the surface of Mars.
"The south polar mountain is larger than the big island of Hawaii, the largest mountain on Earth, as measured from the ocean floor," Dawn principle investigator Chris Russell was reported saying at a 2011 astronomical conference. "It is almost as high as the highest mountain in the solar system, the shield volcano Olympus Mons on Mars."
Liquid water once flowed across the asteroid. Images captured by the Dawn spacecraft revealed curved gullies and fan-shaped deposits within eight different Vesta impact craters. All eight of the craters are thought to have formed within the last few hundred million years, fairly recent in the lifetime of the 4.5-billion-year-old asteroid.
"Nobody expected to find evidence of water on Vesta. The surface is very cold and there is no atmosphere, so any water on the surface evaporates," study lead author Jennifer Scully, a postgraduate researcher at UCLA, said in a NASA statement. "However, Vesta is proving to be a very interesting and complex planetary body."
Scully and her team thought the features were created by debris flows, as opposed to pure-water rivers or streams, sculpted the Vesta gullies. They proposed that meteorites bombarding the asteroid melted ice deposits beneath the surface, sending liquid water and small rocky particles flowing down the crater walls. Such activity suggests the presence of ice buried beneath the surface.
"If present today, the ice would be buried too deeply to be detected by any of Dawn's instruments," Scully said. "However, the craters with curved gullies are associated with pitted terrain, which has been independently suggested as evidence for loss of volatile gases from Vesta."
Ice could have been responsible for modifying Vesta's surface. In 2017, a study suggested that smooth patches of terrain on the asteroid frequently possessed high concentrations of hydrogen, which is often seen when solar radiation breaks down water molecules.
"We suggest that modifications of the surface by melting of buried ice could be responsible for smoothing those areas," Essam Heggy, a planetary scientist at the University of Southern California in Los Angeles, told Space.com. "Buried ice could have been brought to the surface after an impact, which caused heated ice to melt and travel up through the fractures to the surface."
Dawn also observed signs of hydrated minerals (minerals containing water molecules) on Vesta's surface, which could also hint at the presence of buried ice. The hydrated materials were associated with older terrains, and could have been delivered by impacts of material from farther out in the solar system.
A low-altitude map of Vesta revealed a rich geology. The steep slopes found on the asteroid, combined with its high gravity, paves the way for rocks to roll downward, exposing other material. Dawn revealed a variety of mineral, including some bright and dark materials that could relate to potential buried ice.
Vestal visitors to Earth
In fact, Vesta's unique composition means that it is responsible for an entire group of meteorites. The HED meteorites — made up of howardites, eucrites and diogenites — tell the story of Vesta's early life. Eucrites form from hardened lava, while diogenites come from beneath the surface. Howardites are a combination of the two, formed when a large impact mixed the two sections together.
Vesta has been suspected as being the source of the HED meteorites since 1970. Dawn's mapping spectrometer verified that proposition. The Dawn team thinks the HEDs came from an impact basin named Rheasilvia, after an ancient Roman vestal virgin priestess. At 310 miles (500 kilometers) in diameter, Rheasilvia is nearly as large as Vesta itself. It most likely formed from a collision that stripped away most of the southern hemisphere's crust, revealing the asteroid's interior.
"Vesta likely came close to shattering," said Dawn principal investigator Carol Raymond, noting that the blow left concentric sets of troughs — fracture lines — around Vesta's equator.
Parallel troughs may be another sign of the enormous impact. Raymond told the Planetary Society that the presence of those troughs suggests serious damage to the asteroid's interior.
If the orbit of Vesta lies beyond Mars, how did pieces of it manage to arrive on Earth? The fragments of Vesta pass Jupiter once every three orbits around the sun, allowing the gravity of the largest planet to affect them. Such tugging could have shifted the fragments enough to cause their eventual impact with Earth.
As a result, Vesta is one of three bodies from which scientists have samples. The other two are the moon and Mars.
Exploring the asteroid
In September 2007, NASA launched the Dawn mission, which is unique in that it was the first craft to enter orbit around one solar system body, then proceed to a second. Dawn entered orbit around Vesta in July 2011. After studying the asteroid for a year, it left Vesta encountered Ceres in March 2015.
NASA's Dawn mission is to study the characteristics of the early solar system by analyzing the two asteroids, which are very different. Ceres is wet, with seasonal polar caps, and may have a thin atmosphere. Vesta, on the other hand, is dry and rocky. Studying the unique spectral signatures in its rocky crust will expand our knowledge of our own planet, as well as Mars and Mercury.
Given their size, the two are actually regarded as protoplanets, or small planets. The gravitational pull of Jupiter disrupted their formation. Without the presence of the gas giant, the two may well have continued to evolve into full-size planets.
"We now know that Vesta is the only intact, layered planetary building block surviving from the very earliest days of the solar system," Dawn deputy principal investigator Carol Raymond, of NASA's Jet Propulsion Laboratory in Pasadena, California, told reporters in 2012.
Dawn's study of Vesta allowed for the creation of the best map to date of the asteroid.
In October 2010, the Hubble Space Telescope imaged Vesta again. The resulting data revealed that the asteroid was tilted approximately four degrees more than scientists originally thought. These findings helped NASA to place the spacecraft in the appropriate polar orbit around the asteroid. Dawn requires light from the sun in order to perform its mapping and imaging assignments.
The green flash image at the top of this post was taken by Jim Grant, an EarthSky friend on Facebook. He captured it off the coast of Ocean Beach, California, and identified it a mock mirage green flash.
It’s not hard to see a green flash with the eye alone, when sky conditions are right, and when you’re looking toward a very clear and very distant horizon. That’s why those who live near an ocean tend to report green flashes most often. A sea horizon is the best place to see them.
The video below, posted to EarthSky by Vladek in 2016, is an excellent example of the experience of seeing a green flash:
Most people see green flashes just at sunset, at the last moment before the sun disappears below the horizon. Be careful and don’t look too soon. If you do look too soon, the light of the sunset will dazzle (or damage) your eyes, and you’ll miss your green flash chance that day.
But if you wait – looking away until just the thinnest rim of the sun appears above the horizon – that day’s green flash could be yours.
Of course, the green flash can be seen before sunrise, too, although it’s harder at that time of day to know precisely when to look.

There are many different types of green flash. Some describe a streak or ray of the color green … like a green flame shooting up from the sunrise or sunset horizon.
The most common green flash, though – the one most people describe – is a flash of the color green seen when the sun is nearly entirely below the horizon.
Again … you need a distant horizon to see any of these phenomena, and you need a distinct edge to the horizon. That’s why these green flashes, streaks, and rays are most often seen over the ocean. But you can see them over land, too, if your horizon is far enough away.
Pollution or haze on the horizon will hide this instantaneous flash of the color green.
Jim Grant photographed this green flash on April 27, 2012, off the coast of San Diego.
And, of course, Les Cowley at the great website Atmospheric Optics devotes many pages to the green flash phenomenon. Notice the menu bar at the left side of the page; it’ll let you explore many different types of green flashes.

Bottom line: The green flash is legendary, and some people have told us they thought it was a myth, like a unicorn or a pot of gold at the end of a rainbow. But green flashes are very real. You need a distant and exceedingly clear horizon to see them at the last moment before the sun disappears below the horizon at sunset.
