Bob Lazar: Ancient History is Hidden From The Public
Bob Lazar: Ancient History is Hidden From The Public
Bob Lazar was right, the U.S. Military has recovered wreckage from off-world vehicles not made of this earth and one of the recovered wreckage is the UFO that crashed in Roswell in 1947 as well as they found the alien crew from which three aliens didn't survive the crash. The surviving alien was taken to Wright Patterson Air Force Base where it stayed for about nine months before it passed away.
The Roswell UFO crash is perhaps the biggest UFO cover up in history but over the years eyewitnesses told what they had witnessed and all stated that they had seen the surviving alien too.
Read the report Eye-Witnesses’ accounts of the Surviving Alien in which the eyewitnesses tell in detail about the surviving alien that walked away from the crash. All the witnesses stated the same; The being was child-size, four feet, maybe a little more, no hair, and a large head and big eyes shaped like tear-drops, the arms were a bit longer, and the skin was ashy, gray and kind of scaly.
What's more, Bob Lazar said that wreckage were found in an archeological dig, meaning some of these things are ancient. I believe these flying saucers and other craft come from the antediluvian age, or as the world knows it, the age of the lost city of Atlantis.
My guest today, Timothy Alberino says the answer to all these things is found in the Bible and also the ancient book of Enoch, one of the oldest books in the world, which is said to be a historical account of the antediluvian era and a record of a lost civilization.

Previously, it was widely considered that moons were lifeless celestial bodies. However, as we now know, these constant companions of the planets can contain more life than we’d ever dared to think. Titan is one of the most magnificent and spectacular natural satellites.
An artist impression of what the lakes might look like on Titan
As many of you are probably aware, the surface of Saturn’s biggest satellite is covered not only by a thick coating of methane hydrate and water ice, but also by numerous rivers and lakes of liquid ethane and methane. And it’s these intriguing natural structures that folks at Space Daily want to look at in further detail.
Images from the Cassini mission show river networks draining into lakes in Titan’s north polar region.

We’ll look at how these incredible structures form, what part they play in Titan’s natural processes, and what diverse forms the unusual methane lakes on Saturn’s moon take. Watch the video below for more:

The US Navy is regularly at work modifying its carrier-based vehicles and replenishing its already fierce arsenal with new drones.
And it’s one of these that will be in the spotlight of today’s video. The MQ-25 Stingray is a tanker drone that could radically change the rules of the game as far as the intense air battles of the future go!
UAV’s will play an important role once they’ve matured. The applications could be limitless and they’ll free up aircrews. The “Loyal Wingman” project is very promising. The “stealth” versions could be invaluable in SEAD missions.
Discussion of unidentified flying objects — or, as they have recently been rebranded, unidentified aerial phenomena (UAP) — was long relegated to society's fringes. The topic was toxic, and many people avoided serious engagement with it out of fear of being branded a crackpot.
But that has begun to change in the past few years. Prominent scientists now openly push for serious study of UFOs, and the U.S. Navy recently drew up new guidelines that encourage pilots to report curious or confusing sky sights.
Read on for a brief history of UFO sightings, potential explanations for them and cultural attitudes toward the phenomenon.
People have seen intriguing or confounding objects in the sky for as long as we've been looking up.
Over the eons, for example, many different cultures have regarded meteors and comets as supernatural phenomena, or at least processed them through a supernatural lens(opens in new tab). These dramatic sky lights have been deemed manifestations of a deity's displeasure or interpreted as signs that something wonderful, terrible or simply consequential is soon to happen.
Evidence of this view can be found in the 11th-century Bayeux Tapestry, which chronicles the events leading up to the Norman conquest of England in 1066 CE. The famous Halley's Comet zoomed through the inner solar system that same year, and the 230-foot-long (70 meters) tapestry depicts it blazing ominously above the head of England's King Harold II.
"We see the new king sat on a throne, with nobles to the left and Archbishop Stigand to the right," the Reading Museum wrote in a description of the tapestry's comet scene(opens in new tab). (Harold was crowned on Jan. 6, 1066.)
"At the far side, he is cheered on by the masses," the description continued. "On the far right, Halley's Comet appears in the sky. People think it an evil omen and grow terrified. News of the comet is brought to Harold. Beneath him, a ghostly fleet of ships appears in the lower border, a hint of the Norman invasion to come."
Harold was killed by William the Conqueror's troops during the decisive Battle of Hastings, on Oct. 14, 1066.
UFOS: THE EARLY YEARS
The UFO phenomenon as we know it today is much more recent, dating to the era of powered flight. This makes a lot of sense; there weren't nearly as many flying objects to be puzzled by in William the Conqueror's day.
UFOs really took off during World War II, when Allied pilots in both the European and Pacific theaters reported seeing puzzling lights or objects in the sky. They called these curiosities "foo fighters," a term better known today as the band fronted by former Nirvana drummer Dave Grohl.
Then, in June 1947, American businessman and aviator Kenneth Arnold reported seeing nine shiny, mysterious craft zipping through the skies near Washington's Mount Rainier. Some newspaper stories described these UFOs as "flying disks" or "flying saucers," and the latter term soon wormed its way into the public consciousness.
UFO reports surged in the wake of Arnold's sighting, some of them even winding up in the pages of The New York Times(opens in new tab). One of the items the Times picked up was the discovery of some seemingly exotic wreckage on a ranch in Lincoln County, New Mexico in 1947.
In July of that year, a public information officer at the (relatively) nearby Roswell Army Air Field described the debris as a "flying disk," briefly igniting a firestorm of confused interest. Army officials quickly retracted that statement, explaining that the material in question was the remains of a crashed weather balloon, and the "Roswell incident" faded into obscurity.
(It came roaring back three decades later, however, revived by UFO enthusiasts who claimed that the U.S. government had found an alien spacecraft in New Mexico, perhaps even with extraterrestrials inside, and covered the whole thing up. Some conspiracists believe the wreckage was spirited to a hush-hush military site in southern Nevada called Area 51, where study of the aliens and their craft continues to this day.)
The U.S. military, concerned that some of these UFOs might pose a threat to national security, soon began to investigate sightings systematically. The Air Force established Project Sign to this end in 1947, then followed that with the similarly short-lived Project Grudge in 1948. The more well-known Project Blue Book(opens in new tab) got started in 1952 and ran all the way to 1969, examining more than 12,600 UFO reports along the way.
One of the sightings Project Blue Book investigated was that of Betty and Barney Hill, who claimed they were captured and examined by extraterrestrials in rural New Hampshire in September 1961. The couple's account started getting picked up by newspapers in 1965, becoming the first-ever widely publicized alien-abduction story, as History.com noted(opens in new tab).
UFO sightings didn't end when Project Blue Book wrapped up, of course; they've kept on rolling in over the decades.
Some of the most famous ones in the past half-century include that of Travis Walton, an Arizona man whose 1975 alien-abduction claim was dramatized in the 1993 film "Fire in the Sky;" the Rendlesham Forest incident, a string of mysterious observations near England's Royal Air Force Woodbridge station in December 1980; and the Phoenix Lights, which confused many Arizonans in March 1997.
And, in November 2004, several U.S. Navy pilots flying off the coast of San Diego reported seeing bizarre craft zooming through the sky, seemingly maneuvering in ways that exceeded the limits of known technology. Other Navy pilots had similar experiences off the U.S. East Coast a decade later, making a series of intriguing observations from June 2014 to March 2015.
The pilots captured infrared video of some of these encounters using their onboard camera systems. Three of these videos went viral in December 2017 when The New York Times published them as part of a blockbuster story(opens in new tab) about a previously secret military UFO-investigating effort called the Advanced Aerospace Threat Identification Program, or AATIP for short.
Politico(opens in new tab) and The Washington Post(opens in new tab) also published deep dives into AATIP, which was first funded at the request of then-Senator Harry Reid (D-Nev.) and appears to have been a driving force in the rebranding of UFOs to UAP, a term with less historical baggage. The program ran from 2007 until a funding phaseout in 2012, though AATIP personnel have said its work continued in an unofficial capacity for a few years after that.
AATIP has a successor, and it was born in the sunlight, comparatively speaking. In the summer of 2020, the Pentagon announced the establishment of the Unidentified Aerial Phenomena Task Force (UAPTF), whose mission is "to detect, analyze and catalog UAPs that could potentially pose a threat to U.S. national security."
We've seen some of the task force's work already. In June 2021, the Office of the Director of National Intelligence (DNI) released a congressionally mandated report outlining what the UAPTF, the FBI and the Office of Naval Intelligence make of 144 recent UFO encounters documented by U.S. government sensors, with a focus on sightings by Navy pilots between November 2004 and March 2021.
The report, a preliminary nine-page assessment that you can read here(opens in new tab), found that 18 of the 144 UFOs moved in odd or unexpected ways.
"Some UAP appeared to remain stationary in winds aloft, move against the wind, maneuver abruptly or move at considerable speed, without discernible means of propulsion. In a small number of cases, military aircraft systems processed radio frequency (RF) energy associated with UAP sightings," the report states.
UFOs are undeniably real; people often see things in the sky that they can't identify. But that doesn't necessarily mean there's anything exotic going on.
Alien-abduction stories are more complicated, as they tend to involve more psychological components. But some research suggests that at least some such reports may be explained by lucid dreaming, an odd sleep state in which people can control their dreams.
Project Blue Book got to the bottom of the vast majority of the 12,600 sightings it investigated, ascribing most of them to natural phenomena such as clouds, stars and bright planets. The Air Force researchers could not explain 701 of the encounters, but they concluded that none displayed evidence of otherworldly technology or posed a threat to national security.
The 2021 DNI report evinces less certainty, positively identifying just one of the 144 examined UAP. (That lone demystified object was a large, deflating balloon.) The investigators stressed that more data are needed to understand UAP, which likely have multiple explanations. For example, strange and seemingly inexplicable movement patterns "could be the result of sensor errors, spoofing or observer misperception and require additional rigorous analysis," the report states.
Advanced technology developed by foreign adversaries is another potential cause. If foreign tech is indeed behind some of these sightings, UAP would "represent a national security challenge," the report adds.
This possibility has spurred the U.S. military to take the UAP issue more seriously than ever before. In 2019, for example, the Navy formalized its UFO-reporting guidelines, a revision that could remove much of the stigma that has long been associated with sightings, as Politico noted(opens in new tab).
The 2021 DNI assessment does not explicitly mention the alien hypothesis; it's implicitly lumped into a catch-all "other" category of possible explanations. And there are good reasons not to leap to the E.T. conclusion, experts say.
For example, the Navy pilots' sightings in 2004, 2014 and 2015 occurred in coastal waters, which is where you might expect to find advanced reconnaissance craft operated by rival nations, pointed out Seth Shostak, a senior astronomer at the SETI (Search for Extraterrestrial Intelligence) Institute in Mountain View, California. (Flights over the U.S. mainland would be much easier to detect.) And some of the encounters apparently occurred shortly after the Navy jets' radar systems were upgraded, suggesting a glitch of some kind might be responsible.
Indeed, it may be telling that imagery of UFOs, no matter what era it was captured in, tends to depict the objects as fuzzy blobs.
"The sightings always recede to the edge of what technology allows you to do," Shostak told Space.com in 2019. "The aliens are kind of keeping pace with technology."
Common sense also argues for relatively mundane, terrestrial explanations, and not just because of Occam's Razor (the simplest explanation is usually the best one). For example, if some UFOs are indeed alien spacecraft, what exactly are they up to?
"If the aliens are here, you gotta say they're the best houseguests ever, because they never do anything," Shostak said. "They just buzz around. They don't address climate change; they don't steal our molybdenum."
Still, the E.T. idea should not be dismissed or ridiculed, Shostak and others argue. It's not very scientific to eliminate a hypothesis out of hand, after all, and some UAP encounters are very difficult to explain.
For example, the November 2004 Navy sightings off the California coast were made by four pilots in two different jets, and they saw the bizarre, fast-moving object with their own eyes, two of the aviators told the CBS news program "60 Minutes" in 2021(opens in new tab). That rules out the possibility that an instrument glitch was responsible in that case. And the same UAP was also documented by radar.
"It's not trivial to say what these things are," Shostak said.
There's a growing willingness to entertain all possible explanations, including the alien hypothesis, for such encounters. For example, in July 2021, Harvard astronomer Avi Loeb and colleagues announced a venture called the Galileo Project, which will look for evidence of extraterrestrial civilizations (ETCs) using a network of new telescope systems around the world.
Among other aims, the Galileo Project will attempt to determine the true nature of UAP and odd bodies such as 'Oumuamua, the first interstellar object ever observed in our own solar system.
'Oumuamua's strangeness led Loeb to suggest that the visitor may be a defunct alien spacecraft. This notion, while still well out of the scientific mainstream, is less outre today than it would have been just a decade or so ago, largely because of the exoplanet revolution.
In recent years, astronomers have learned that roughly 20% of the Milky Way's 200 billion or so stars probably harbor a rocky planet in their "habitable zone," the range of orbital distances in which liquid water could exist on a world's surface. And a world doesn't have to be in the habitable zone to harbor habitable environments. Multiple moons in our own solar system, such as Jupiter's Europa and Saturn's Enceladus, sport huge oceans beneath their icy shells, after all.
"Given the recently discovered abundance of habitable-zone exoplanets, with potential for extraterrestrial life, the Galileo Project is dedicated to the proposition that humans can no longer ignore the possible existence of ETCs," Loeb said in a July 2021 statement(opens in new tab).
"Science should not reject potential extraterrestrial explanations because of social stigma or cultural preferences that are not conducive to the scientific method of unbiased, empirical inquiry," he added. "We now must 'dare to look through new telescopes,' both literally and figuratively."

Voyager 1 enters interstellar space in this artist's concept.
NASA/JPL-Caltech
The Voyager spacecraft have been flying through space for nearly 45 years, so seeing recent headlines that these interstellar pioneers are powering down understandably caused some waves.
But are the Voyager spacecraft really about to be shut down?
To clarify the situation, Astronomy reached out to the mission press officer Calla Cofield who was quick to correct the impression, saying, “nothing new is starting now.” She went on to explain that NASA is following a strategic plan to keep their oldest explorers going for as long as possible.
The Voyager mission estimates the spacecrafts entered interstellar space in 2012 (Voyager 1) and 2018 (Voyager 2).
NASA/JPL-Caltech
Keeping the lights on
The twin Voyager spacecraft left Earth nearly five decades ago; Voyager 2 left our planet Aug. 20, 1977, with Voyager 1 following shortly after on Sept. 5. Both spacecraft are powered by three radioisotope thermoelectric generators (RTGs) and have a host of instruments collecting and sending scientific data back to Earth. (In Voyager 1’s case it takes about 20 hours and 33 minutes for that data to reach us!)
Now, the RTGs aboard the Voyager spacecraft turn heat into electricity in order to power the probes. That heat comes from the decay of plutonium-238 radioisotopes. However, at this point in their lifetimes, the generators are producing about 40 percent less electricity than when they were first launched.
To keep them running for as long as possible, NASA began aggressively planning which systems to shut off in 2019. But the agency has been tackling the problem of diminishing power for decades now. “After 45 years in flight,” says Cofield, “the power budget is getting to the point where the team has to turn off whatever they can to keep the spacecraft running and doing science.”
NASA lists the instruments that have been powered down on the mission website.
Over the last three years, this has involved turning off the heaters to five of the probes' scientific instruments."Amazingly, all five have continued to operate well below the temperatures they were tested at!” says Cofield.
The Voyager Science Steering Group will make further decisions on maintaining the power budget for the Voyager mission this August. According to Cofield, the creativity and innovation of the engineering team means that, in theory, the plans could stretch the Voyager missions into the 2030s — half a century longer than the probes were originally expected to last. However, that would require the team to turn off even more scientific instruments at some point.
So, at least as it stands now, the Voyager spacecraft aren’t going anywhere (other than interstellar space) any time soon!
Astronomers Capture the Sharpest Image yet of a Monster Galaxy 12.4 Billion Light Years Away
Astronomers Capture the Sharpest Image yet of a Monster Galaxy 12.4 Billion Light Years Away
A team of scientists obtained a magnificent photograph of a faraway galaxy, reminding us all how little we are in the grand scheme of things.
This monster galaxy’ is around 12 billion light-years away from Earth and produces new stars 1,000 times faster than our own Milky Way galaxy.
Scientists utilized the £1.1 billion ALMA Observatory in Chile to capture views of the galaxy with a resolution ten times better than any previous attempt, naming it ‘COSMOS-AzTEC-1.’
The measurements revealed previously unknown information on the structure of this starburst galaxy, which is thought to have originated in the first billion years following the big bang.
Monster galaxies, or starburst galaxies, form stars at a startling pace; 1000 times higher than the star formation in our Galaxy. But why are they so active? To tackle this problem, researchers need to know the environment around the stellar nurseries. Drawing detailed maps of molecular clouds is an important step to scout a cosmic monster.
Tadaki and the team targeted a chimerical galaxy COSMOS-AzTEC-1. This galaxy was first discovered with the James Clerk Maxwell Telescope in Hawai`i, and later the Large Millimeter Telescope (LMT) in Mexico found an enormous amount of carbon monoxide gas in the galaxy and revealed its hidden starburst. The LMT observations also measured the distance to the galaxy, and found that it is 12.4 billion light-years.
Monster galaxy COSMOS-AzTEC-1 observed with ALMA. ALMA revealed the distribution of molecular gas (left) and dust particles (right). In addition to the dense cloud in the center, the research team found two dense clouds several thousand light-years away from the center. These dense clouds are dynamically unstable and thought to be the sites of intense star formation.

Astronomers obtained the most detailed anatomy chart of a monster galaxy located 12.4 billion light-years away. Using the Atacama Large Millimeter/submillimeter Array (ALMA), the team revealed that the molecular clouds in the galaxy are highly unstable, which leads to runaway star formation. Monster galaxies are thought to be the ancestors of the huge elliptical galaxies in today’s Universe, therefore these findings pave the way to understand the formation and evolution of such galaxies.
“One of the best parts of ALMA observations is to see the far-away galaxies with unprecedented resolution,” says Ken-ichi Tadaki, a postdoctoral researcher at the Japan Society for the Promotion of Science and the National Astronomical Observatory of Japan, the lead author of the research paper published in the journal Nature.
Researchers have found that COSMOS-AzTEC-1 is rich with the ingredients of stars, but it was still difficult to figure out the nature of the cosmic gas in the galaxy. The team utilized the high resolution and high sensitivity of ALMA to observe this monster galaxy and obtain a detailed map of the distribution and the motion of the gas. Thanks to the most extended ALMA antenna configuration of 16 km, this is the highest resolution molecular gas map of a distant monster galaxy ever made.
“We found that there are two distinct large clouds several thousand light-years away from the center,” explains Tadaki. “In most distant starburst galaxies, stars are actively formed in the center. So it is surprising to find off-center clouds.”
The astronomers further investigated the nature of the gas in COSMOS-AzTEC-1 and found that the clouds throughout the galaxy are very unstable, which is unusual. In a normal situation, the inward gravity and outward pressure are balanced in the clouds. Once gravity overcomes pressure, the gas cloud collapses and forms stars at a rapid pace. Then, stars and supernova explosions at the end of the stellar life cycle blast out gases, which increase the outward pressure. As a result, the gravity and pressure reach a balanced state and star formation continues at a moderate pace. In this way star formation in galaxies is self-regulating. But, in COSMOS-AzTEC-1, the pressure is far weaker than the gravity and hard to balance. Therefore this galaxy shows runaway star formation and has morphed into an unstoppable monster galaxy.
The team estimated that the gas in COSMOS-AzTEC-1 will be completely consumed in 100 million years, which is 10 times faster than in other star forming galaxies.
But why is the gas in COSMOS-AzTEC-1 so unstable? Researchers do not have a definitive answer yet, but galaxy merger is a possible cause. Galaxy collision may have efficiently transported the gas into a small area and ignited intense star formation.
“At this moment, we have no evidence of merger in this galaxy. By observing other similar galaxies with ALMA, we want to unveil the relation between galaxy mergers and monster galaxies,” summarizes Tadaki.
China's ambitious plan to find the first Earth 2.0
China's ambitious plan to find the first Earth 2.0
Despite several high profile missions to find an Earth-like planet orbiting a Sun-like star, astronomers have failed to find one. Now the Chinese are launching their own space telescope to hunt for Earth 2.0.
Aleksandr Kukharskiy/Shutterstock
The Kepler Space Telescope made some of the most exciting discoveries in astronomy. Launched in 2009, the telescope observed 13 million stars until 2018, when it was de-activated.
During that time, Kepler discovered over 2600 planets orbiting other stars. Some were entirely unlike anything in our Solar System, forcing astronomers to invent two new classes of planet. One or two of Kepler’s discoveries even orbit in the habitable zone of their parent star, albeit around red dwarf stars that are rather different from our Sun. This was hugely exciting because this temperate region in which liquid water can exist has conditions thought crucial for the existence of life.
But for all that, Kepler ultimately failed. Its mission was to find another Earth, in other words an Earth-like planet orbiting a Sun-like star. But in nearly a decade of observations, Kepler found not a single Earth 2.0.
That was partly because Sun-like stars turned out to be noisier than expected and so required longer observation times. But also because in 2013, two of the observatory’s four reaction wheels broke down, making long-term observations impossible. As a result, astronomers have yet to find an alien Earth.
Scanning the Heavens
That could now change thanks to a Chinese mission called Earth 2.0 due to be launched in 2026. This mission will scan the heavens for Earth-like planets orbiting Sun-like stars with instruments designed to cope with the star-noise that Kepler unexpectedly discovered.
The team involves some 300 scientists and engineers from over 40 institutions, most in China. And this week, the collaboration published a detailed description of the mission on the arXiv.
One problem for any space observatory is to cover as a wide a field-of-view as possible while minimizing the cost and weight of the spacecraft. The Chinese team solved this problem by avoiding the cost and weight of a single giant telescope.
Instead, the spacecraft will carry six smaller 30cm telescopes that together will observe a similar area of sky as Kepler, which had a 1.4-meter mirror. These telescopes will look for the characteristic changes in star brightness as a planet passes in front of it.
The spacecraft will also carry a seventh telescope designed to look for microlensing events in which the gravitational field of a star focuses the light from a distant star behind it, temporarily brightening it. By studying the pattern of brightness, astronomers can tell if the star has an orbiting planet.
This seventh instrument will also be able to spot free floating planets, thereby helping to cast some light on these strange, lonely objects.
Data Firehose
The Chinese team’s plan is to launch Earth 2.0 to the L2 Lagrange point, one of several regions of space where the Earth and Moon’s gravitational fields are in balance, and away from Earth’s potential interference. L2 is a popular choice for observatories and home to several past and present, such as the Herschel Space Observatory and the James Webb Space Telescope. The Earth 2.0 spacecraft will orbit L2 over the course of 4 years, sending back some 169 Gb of data every day.
That raises the prospect of some mouth-watering discoveries. “Simulations show that the transit survey will be able to detect ∼ 29,000 new planets, including ∼ 4,900 Earth-sized planets,” the team say. That means the mission should detect between and 10 and 20 Earth 2.0s by 2030.
The discovery of the first Earth 2.0 is likely to be one of the defining moments in the history of astronomy. It is likely to create huge interest in the nature of these planets, the make-up of their atmospheres and the potential presence of water. Then there will be the search for biomarkers suggesting the presence of life, molecules like methane and oxygen, and the characteristic light absorption patterns of photosynthesis. Beyond that will be the search for technosignatures that might indicate the presence of a civilization, signals such as industrial pollutants like chlorofluorocarbons and even narrowband radio transmissions.
Of course, Earth 2.0 isn’t the only mission capable of spotting an alien Earth. Several others have the capability, such as ESA’s Plato mission which will also be launched in 2026. But these will have to be luckier than Earth 2.0 to be successful.
That sets the scene for an exciting international race to discover an “other Earth” and the beginning of a new era in the study of potentially habitable planets.
UFOs – Ultra-red Flattened Objects – revealed by Webb
UFOs – Ultra-red Flattened Objects – revealed by Webb
Posted by Kelly Kizer Whitt
See one of the red UFOs – Ultra-red Flattened Objects – that appears in the Webb image (right), but not the Hubble image (left)? Webb is finding galaxies that Hubble missed. Image via Erica Nelson, et al./ arXiv.
UFOs in Webb’s range
The James Webb Space Telescope (JWST) is the successor to the Hubble Space Telescope (HST). It can see farther away in space, and so farther back in time. In operation only since this summer, it’s already discovering things Hubble couldn’t see, including some massive, deep-red, disk-shaped galaxies. Astronomers call them HST-dark galaxies. In a paper published on arXiv on August 2, 2022 (but not yet peer-reviewed), a team of scientists are also calling these galaxies Ultra-red Flattened Objects, or UFOs.
And – to Webb’s “eye” at least – they do have the classic, sci-fi look of a flying saucer!
Deep-red galaxies not visible to Hubble
These deep-red, disk-shaped galaxies have a redshift (or z) between 2 and 6. That value means we’re seeing them as they were in the universe 10.3 to 12.7 billion years ago. So they’re definitely not our next-door neighbors. But they are within the range of what Hubble could image, if it could see their red light.
Webb can see these “HST-dark” galaxies because it observes in infrared light, which is the part of the spectrum where these galaxies shine. The team that published the new study, led by Erica Nelson of the University of Colorado, Boulder, found 29 of these HST-dark galaxies. The galaxies have a significant amount of dust, which makes their light redder and hides them from Hubble’s vision. But Webb’s infrared sensors can see through that dust, making the UFOs pop into view.
Webb’s galactic discoveries
Compare the UFOs to the record-breaking distant galaxies that Webb has spied, which have redshifts of 11-20. That would be when the universe was between 400 million and 150 million years old. The UFOs, with a redshift of 2-6, existed when the universe was between 3 1/2 and 1 billion years old (out of its current 13.7 billion years of age). So these galaxies aren’t real close to us in time, but they are still closer than the record-breaking discoveries.
UFOs at cosmic noon
The astronomers refer to the time period that UFOs thrived as cosmic noon. The early ages of the universe when galaxies began to grow was the cosmic dawn. Then cosmic noon arrived, about 3 billion years after the Big Bang. Astronomers think most of the universe’s stars and black holes formed around the time of cosmic noon. And now astronomers say that these UFOs, or dusty star-forming galaxies undergoing extreme starbursts, dominate the total star formation rate budget of the universe during cosmic noon. So, as the paper said, since we have not yet been able to study what we could not see:
… we do not yet fully understand the growth of the most massive galaxies at cosmic noon.
From flattened to bulging
The scientists also said that these massive, dusty UFOs may be the progenitors of today’s large elliptical galaxies. They’re surprised by this finding, because astronomers believed that the bulging elliptical galaxies we see now would have already had that bulging shape at an early age. But as the paper said:
Perhaps the most noteworthy result stems from the flattened shapes of these HST-dark galaxies. These massive, star-forming galaxies are the likely progenitors of today’s massive galaxies, which tend to be bulge/spheroid-dominated … The expectation may have been that the stellar bodies of these objects would already host significant bulges. This, however, is not what we observe in this sample.
M87 is a large elliptical galaxy famous for the black hole at its center. The Hubble Space Telescope took this image in 2009. M87 lies about 55 million light-years away. It may have begun life as a UFO, or Ultra-red Flattened Object.
The discovery of these UFOs is helping astronomers get a better picture of the universe at a more recent age. As the paper noted:
The stellar masses, sizes, and morphologies of the sample suggest that some could be progenitors of lenticular or fast-rotating galaxies in the local Universe. The existence of this population suggests that our previous censuses of the universe may have missed massive, dusty edge-on disks, in addition to dust-obscured starbursts.
The paper concluded:
This sample highlights the fact that the JWST discovery extends studies of galaxy stellar structures to later cosmic epochs during which we thought we had a reasonable census of the universe already.
Bottom line: Astronomers analyzing new Webb images have found UFOs, or Ultra-red Flattened Objects. These UFOs are disk galaxies that only become visible in infrared light.

Using the James Webb Space Telescope (JWST), an international team of astronomers have detected a new faint, distant, and cold brown dwarf. The newly found object, designated GLASS-JWST-BD1, turns out to be about 31 times more massive than Jupiter. The discovery was detailed in a paper published July 29 on arXiv.org.
Brown dwarfs are intermediate objects between planets and stars. Astronomers generally agree that they are substellar objects occupying the mass range between 13 and 80 Jupiter masses. One subclass of brown dwarfs (with effective temperatures between 500 and 1,500 K) is known as T dwarfs, and represents the coolest and least luminous substellar objects so far detected.
Studies of T dwarfs could help astronomers better understand objects near the disputed planet/star boundary, for instance, giant exoplanets. However, although many brown dwarf have been detected to date, T dwarfs are not so common, as only about 400 such objects have been identified.
Now, a group of astronomers led by Mario Nonino of the Astronomical Observatory of Trieste in Italy, reports the finding of a new brown dwarf that is most likely of T dwarf subclass. The discovery was made as part of the Through the Looking GLASS (GLASS-JWST) project—a JWST Early Release Science (ERS) program targeting the massive galaxy cluster Abell 2744 with JWST's Near-Infrared Spectrograph (NIRSPEC) and Near-Infrared Imager and Slitless Spectrograph (NIRISS).
"We present the serendipitous discovery of a late T-type brown dwarf candidate in JWST NIRCam observations of the Early Release Science Abell 2744 parallel field. The discovery was enabled by the sensitivity of JWST at 4 µm wavelengths and the panchromatic 0.9–4.5 µm coverage of the spectral energy distribution," the researchers wrote in the paper.
According to the study, GLASS-JWST-BD1 has a mass of about 31.43 Jupiter masses and an effective temperature of some 600 K. The age of this brown dwarf was estimated to be 5 billion years.
Comparison with theoretical models suggest that GLASS-JWST-BD1 is a late-type T dwarf. Its distance was measured to be between 1,850 and 2,350 light years, in a direction perpendicular to the Galactic plane. The results indicate that this object is likely a member of the Galactic thick disk or halo population.
The astronomers noted that further observations of GLASS-JWST-BD1 are required in order to confirm its T-dwarf nature. In particular, kinematic or chemical abundance data are needed to get more insights into the properties of this object.
In concluding remarks, the authors of the paper underlined how their discovery demonstrates the capability of JWST to investigate distant low-mass Galactic stellar and substellar objects.
"The large estimated distance of GLASS-JWST-BD1 confirms the power of JWST to probe the very low-mass end of the stellar and substellar mass function in the Galactic thick disk and halo, enabling exploration of metallicity dependence on low-mass star formation and the evolution of brown dwarf atmospheres," the scientists wrote.
A chance alignment between Earth and a Mars-bound spacecraft has given us a rare glimpse into the movement of high-energy particles from the Sun.
A chance alignment between Earth and a Mars-bound spacecraft has given us a rare glimpse into the movement of high-energy particles from the Sun. The data from this event can help researchers understand the radiation environment near Mars — a key factor in planning crewed missions to our neighboring planet and beyond.
ENERGETIC PARTICLE PARADE

The space between the planets in our solar system is filled with a wispy sea of charged particles that flow out from the Sun’s atmosphere. This particle population is augmented by cosmic rays — speedy protons and atomic nuclei accelerated in extreme environments across the universe — which ebb and flow against the 11-year solar activity cycle. This undulating particle background is punctuated by bursts of high-energy particles from the Sun, which can be unleashed suddenly in violent solar storms.
Spacecraft that venture out from the protection of Earth’s magnetic field must navigate this ocean of particles and weather solar storms. And if we someday wish to send astronauts to other planets, we’ll need to know how high-energy solar particles, which pose a risk to the health of astronauts and electronic systems alike, travel through the solar system.
WHEN SPACECRAFT ALIGN

In a new publication, a team led by Shuai Fu (Macau University of Science and Technology), Zheyi Ding (China University of Geosciences), and Yongjie Zhang (Chinese Academy of Sciences) studied the high-energy solar particles produced in an event in November 2020, when the Sun emitted a solar flare and a massive explosion of solar plasma called a coronal mass ejection.
This event coincided with a chance alignment of multiple spacecraft along the same solar magnetic field line. This alignment meant that several spacecraft near Earth and the Tianwen-1 spacecraft en route to Mars measured the same burst of energetic particles millions of miles apart, providing a rare opportunity to study how energetic particles from the Sun travel through space along magnetic field lines.
DIFFUSION AND EVOLUTION
Comparison of proton fluence (number of particles collected per unit area) measured by spacecraft at Earth (blue) and by Tianwen-1 at 1.39 au (red). The time increases from (a) to (h). The spectra at Earth and at Tianwen-1 “break” or bend at roughly the same energy, suggesting that there is little evolution as the particles travel outward. Click to enlarge. Fu et al. 2022
By comparing the timing of measurements from Tianwen-1 to those from three spacecraft near Earth, the team discerned that the magnetic field line that connected the spacecraft did not connect back to the origin of the particles. This means that the particles must have traveled, or diffused, across magnetic field lines to reach the spacecraft.
In addition, the team found that the shape of the particle energy distribution remained the same at moderate and high energies as the particles traveled between Earth and Tianwen-1’s location at 1.39 au. This suggests that the shape of the energy distribution is determined earlier, at the time the particles are accelerated to high energies, rather than as the particles travel through space.
The November 2020 event marked the first solar energetic particle event observed by Tianwen-1, but surely not the last. The spacecraft will continue to monitor high-energy particles from its station in Mars orbit as the solar cycle revs up, collecting valuable data for understanding the radiation environment around Mars and planning future missions.

Possible UFO appears during live broadcast in Germany
Possible UFO appears during live broadcast in Germany
Was a UFO accidentally filmed during an ARD live broadcast recording of a wildfire in eastern Germany?
The video footage appears to show a high speed cylindrical object flying by in the background.
The object has no obvious signs of propulsion and no wings, also it can't be a bird either since we don't see flapping wings. Maybe an insect flying close to the camera? But can an insect fly that speed? What could it be?

This bright UFO was seen and recorded in the sky above Anza, California on 6th August 2022.
Witness report:
I saw a fireball in the sky that changed colors from red to orange and changed in size. I was able to get a video of it on my iPhone 13. There was also a small white light that blinked intermittently on the left of it. The red object seemed to have control of the power like a jet engine going on and off. It hovered for a while and then it just disappeared.
Astronomers Discover A Disappearing Space Object That Turns On And Off Every 20 Minutes And Sends Highly-Polarized Radio Signals
Astronomers Discover A Disappearing Space Object That Turns On And Off Every 20 Minutes And Sends Highly-Polarized Radio Signals
According to a research paper published in Nature, astronomers detected a “really weird” object 4,000 lightyears distant from Earth. Every other minute, the object vanishes from view and produces a massive burst of radio waves three times an hour.
Tyrone O’Doherty, a Curtin University student, first noticed the enigmatic object while scanning the sky in rural Western Australia. “It’s exciting that the source I identified last year has turned out to be such a peculiar object,” stated O’Doherty in a press statement.
The object, which the scientists claim is unlike anything else they’ve observed, emits a tremendous beam of radiation that, every 20 minutes, shines brightly in the sky. It also spins and vanishes every minute.
Scientists refer to space objects that “turn” on and off in the night sky as “transients”.
“When studying transients, you’re watching the death of a massive star or the activity of the remnants it leaves behind,” said Dr. Gemma Anderson, an ICRAR-Curtin astrophysicist and co-author of the work.
Slower transients, such as supernovae, might arrive in a matter of days and last for several months. Fast transients, such as neutron stars, “flash” on and off many times per second. However, transients between those two speeds are uncommon, and the current discovery is “really weird” and “completely unexpected.” according to the researchers.
“It was kind of spooky for an astronomer because there’s nothing known in the sky that does that,” said astrophysicist Dr. Natasha Hurley-Walker, who headed the research team. “And it’s really close to us – about 4000 lightyears distant. It’s there in our galaxy’s backyard.”
Hurley-Walker characterized the enigmatic object as being smaller than the sun yet brilliant, radiating highly polarized radio waves three times an hour. These radio pulses imply that it has an “extremely strong” magnetic field, which may correspond to a previously anticipated astrophysical object that has never been verified to exist. Scientists refer to the hypothetical item as an “ultra-long period magnetar.”
“It’s a type of slowly spinning neutron star that has been predicted to exist theoretically,” Hurley-Walker explained. “However, no one anticipated to immediately discover one like this since they were not thought to be that brilliant. It converts magnetic energy to radio waves considerably more efficiently than anything else we’ve seen previously.”

Astronomers believe it is a rare sort of neutron star or a collapsing white dwarf, but they need to examine it again to establish if it is a fluke or a new type of space object.
Ancient Source of Oxygen for Life Discovered Hidden Deep in the Earth’s Crust
Ancient Source of Oxygen for Life Discovered Hidden Deep in the Earth’s Crust
ByNEWCASTLE UNIVERSITY
Researchers have uncovered a source of oxygen that may have influenced the evolution of life before the advent of photosynthesis.
Scientists at Newcastle University have discovered a source of oxygen deep in the Earth’s crust that may have influenced the evolution of life before the advent of photosynthesis.
The pioneering research project uncovered a mechanism that can generate hydrogen peroxide from rocks during the movement of geological faults. The study was led by Newcastle University’s School of Natural and Environmental Sciences and published today (August 8) in the journal Nature Communications.
While hydrogen peroxide in high concentrations can be harmful to life, it can also provide a useful source of oxygen to microbes. This additional source of oxygen may have influenced the early evolution, and possibly even origin, of life in hot environments on the early Earth before the evolution of photosynthesis.
Researchers were able to simulate some of the key conditions of subsurface rock fracturing using vials in the lab. Rocks representative of oceanic and continental crust were crushed under nitrogen, added to oxygen-free water, then heated.

In tectonically active regions, the movement of the Earth’s crust not only generates earthquakes but also riddles the subsurface with cracks and fractures. These are lined with highly reactive rock surfaces containing many imperfections, or defects. Water can then filter down and react with these defects on the newly fractured rock.
Master’s student Jordan Stone simulated these conditions in the laboratory by crushing granite, basalt, and peridotite – rock types that would have been present in the early Earth’s crust. These were then added to water at varying temperatures under well-controlled oxygen-free conditions.
The research investigates a source of reactive oxygen associated with geological faulting; a potential oxygen source prior to cyanobacteria oxygenating the Earth’s atmosphere. This reactive oxygen may have had a role in the evolution of life from an oxygen-free to an oxygenated world and contributed to prebiotic chemistry in subsurface fractures prior to the origin of life.

The experiments revealed that substantial amounts of hydrogen peroxide – and as a result, potentially oxygen – were only generated at temperatures close to the boiling point of water. Importantly, the temperature of hydrogen peroxide formation overlaps the growth ranges of some of the most heat-loving microbes on Earth called hyperthermophiles, including evolutionary ancient oxygen-using microbes near the root of the Universal Tree of Life.
Lead author Jordan Stone, who conducted this research as part of his Master of Research in Environmental Geoscience, said: “While previous research has suggested that small amounts of hydrogen peroxide and other oxidants can be formed by stressing or crushing of rocks in the absence of oxygen, this is the first study to show the vital importance of hot temperatures in maximizing hydrogen peroxide generation.”

Principal Investigator Dr. Jon Telling, Senior Lecturer, added: “This research shows that defects on crushed rock and minerals can behave very differently to how you would expect more ‘perfect’ mineral surfaces to react. All these mechanochemical reactions need to generate hydrogen peroxide, and therefore oxygen, is water, crushed rocks, and high temperatures, which were all present on the early Earth before the evolution of photosynthesis and which could have influenced the chemistry and microbiology in hot, seismically active regions where life may have first evolved.”

NASA's 'Helical Engine' could reach 99% the speed of light
NASA's 'Helical Engine' could reach 99% the speed of light
When it comes to space, there's a problem with our human drive to go all the places and see all the things. A big problem. It's, well, space. It's way too big. Even travelling at the maximum speed the Universe allows, it would take us years to reach our nearest neighbouring star.
But another human drive is finding solutions to big problems. And that's what NASA engineer David Burns has been doing in his spare time. He's produced an engine concept that, he says, could theoretically accelerate to 99 percent of the speed of light - all without using propellant.
He's posted it to the NASA Technical Reports Server under the heading "Helical Engine", and, on paper, it works by exploiting the way mass can change at relativistic speeds - those close to the speed of light in a vacuum. It has not yet been reviewed by an expert.
Understandably this paper has caused buzz approaching levels seen in the early days of the EM Drive. And yes, even some headlines claiming the engine could 'violate the laws of physics'.
But while this concept is fascinating, it's definitely not going to break physics anytime soon. As a thought experiment to explain his concept, Burns describes a box with a weight inside, threaded on a line, with a spring at each end bouncing the weight back and forth. In a vacuum - such as space - the effect of this would be to wiggle the entire box, with the weight seeming to stand still, like a gif stabilized around the weight.Overall, the box would stay wiggling in the same spot - but if the mass of the weight were to increase in only one direction, it would generate a greater push in that direction, and therefore thrust.
According to the principle of the conservation of momentum - in which the momentum of a system remains constant in the absence of any external forces - this should be not completely possible.
But! There's a special relativity loophole. Hooray for special relativity! According to special relativity, objects gain mass as they approach light speed. So, if you replace the weight with ions and the box with a loop, you can theoretically have the ions moving faster at one end of the loop, and slower at the other.
But Burns' drive isn't a single closed loop. It's helical, like a stretched out spring - hence "helical engine".
"The engine accelerates ions confined in a loop to moderate relativistic speeds, and then varies their velocity to make slight changes to their mass. The engine then moves ions back and forth along the direction of travel to produce thrust," he wrote in his abstract.
"The engine has no moving parts other than ions traveling in a vacuum line, trapped inside electric and magnetic fields."
It sounds really nifty, right? And it is - in theory. But it's not without significant practical problems.
According to New Scientist, the helical chamber would have to be pretty large. Around 200 metres (656 feet) long and 12 metres (40 feet) in diameter, to be precise.
And it would need to generate 165 megawatts of energy to produce 1 newton of thrust. That's the equivalent of a power station to produce the force required to accelerate a kilogram of mass per second squared. So a lot of input for a teeny tiny output. It is horribly inefficient.
But in the vacuum of space? It just might work. "The engine itself would be able to get to 99 per cent the speed of light if you had enoughAnd here's the other thing. Humans - not all of us, but still more than a few - desperately want to go to interstellar space. We may never get there. But if we never even try to think about it, that "may" becomes a "definitely." What's that saying - you miss 100 percent of the shots you don't take?time and power," Burns told New Scientist.
Burns notes the efficiency problem in his presentation, and also adds that his work hasn't been reviewed by experts, and there may be errors in his maths. We don't exactly have the blueprints for a fully functional space travel engine here.
What we do have is a piece of groundwork that could be used to develop such an engine. What we have is a dream of the stars.
The hush-hush vehicle is thought to be a space plane.

For the second time in two years, China has launched a classified reusable vehicle on a mystery mission to Earth orbit.
A Long March 2F rocket carrying a "test spacecraft" lifted off from Jiuquan Satellite Launch Center in the Gobi Desert on Thursday (Aug. 4; Aug. 5 Beijing time), China's state-run Xinhua news agency reported.
"The test spacecraft will be in orbit for a period of time before returning to the scheduled landing site in China, during which reusable and in-orbit service technology verification will be carried out as planned to provide technical support for the peaceful use of space," Xinhua wrote(opens in new tab) (in Chinese; translation by Google).
That's about all we know; Xinhua's update is just two paragraphs long and provides no further detail. But the mystery vehicle is thought to be a robotic space plane, perhaps one roughly the same size as the U.S. Space Force's X-37B, based on the Long March 2F's considerable payload capacity, SpaceNews reported(opens in new tab).
China also launched a reusable test spacecraft in September 2020, under a similar cloud of secrecy. That vehicle — which may or may not be the same one that lifted off on Thursday — stayed aloft for two days and released a small payload in orbit before coming down for a landing in China, SpaceNews noted.
For comparison, the X-37B space plane has been orbiting Earth for more than 800 days on its latest mystery mission, the sixth for the X-37B program. The Space Force is thought to have two of the 29-foot-long (8.8 meters), Boeing-built space planes in its fleet.
The Jiuquan launch was part of an extremely busy day in spaceflight. Thursday featured six rocket launches, starting with Rocket Lab's lofting of a spy satellite for the U.S. National Reconnaissance Office at 1 a.m. EDT (0500 GMT).

The quadrupedal robots are well suited for repetitive tasks.

Man's new best friend is coming to the U.S. Space Force.-
The Space Force has conducted a demonstration using dog-like quadruped unmanned ground vehicles (Q-UGVs) for security patrols and other repetitive tasks. The demonstration used at least two Vision 60 Q-UGVs, or "robot dogs", built by Ghost Robotics and took place at Cape Canaveral Space Force Station on July 27 and 28.
According to a statement(opens in new tab) from the Department of Defense, Space Launch Delta 45 will use the robot dogs for "damage assessments and patrol to save significant man hours." The unit is responsible for all space launch operations from Kennedy Space Center and Cape Canaveral.
Images from the demonstration show personnel operating the robots with a hand controller inside a hangar. The Ghost Robotics Vision 60 Q-UGVs can be equipped with a wide variety of optical and acoustic sensors, enabling them to serve as automated "eyes and ears" around sensitive installations such as a Space Force base. The robots can be operated either autonomously or by a human controller and can even respond to voice commands.

The dog-like robots can also serve as miniaturized communications nodes, carrying antennas to quickly extend networks beyond existing infrastructure or in locations where no such infrastructure exists.

The robots have been previously tested by the U.S. Air Force for perimeter defense tasks and as part of a large test of the service's Advanced Battle Management System (ABMS) data-sharing network. In that 2020 test, robot dogs at Nellis Air Force Base in Nevada "provided real-time strike targeting data to USAF operators" in Florida using Starlink satellite links, then-CEO of Ghost Robotics Jiren Parikh told The War Zone(opens in new tab).
The Ghost Robotics Q-UGVs are designed to withstand water and weather, and were recently demonstrated with a tail-like payload enabling them to travel underwater(opens in new tab).
Aside from their military applications, the robot dogs are also being eyed for uses in emergency management, public safety and industrial inspection.
