What happens when a UFO crashes? Some experts claim that the UFO wreckage and even the pilots are transported to a top-secret facility in Dayton, Ohio called Hangar 18 located on Wright Patterson Air Force Base. Declassified Government documents prove that the disk from the famous Roswell event and fragments of other mysterious crashes were shipped to Wright Patterson. Hear stories involving elected officials, UFO researchers, and former base employees, some of whom are going on the record regarding Hangar 18. They spin a tale of flying saucer debris, alien bodies, cryogenic chambers and a vast underground network that may hold the secrets to the UFO mystery. Is there a conspiracy to hide UFO evidence from the highest branches in the U.S. Government, or is it all just a myth?

Witness Claims UFOs Performed Multiple Late Night Reconnaissance Flights Over A City In Arizona
Witness Claims UFOs Performed Multiple Late Night Reconnaissance Flights Over A City In Arizona
Orb-shaped bright light UFOs were spotted in the sky conducting multiple low-altitude flights. The incident reportedly took place over Chandler City in Maricopa County, Arizona in a three-hour period on the evening of August 19-20, 2016.
The unnamed witness reported the sighting to Mutual UFO Network, which filed it as Case 78571. He believes that the spaceships of alien origin may have performed five separate reconnaissance flights over the city on the evening of August 19 and early hours of August 20. The two UFOs may have been extraterrestrials as they were not something he had ever witnessed.
The witness recorded his encounter and submitted a report to MUFON along with three separate videos showing strange aerial activity in the sky.
The first sighting took place at around 9:15 p.m. PST, northeast direction. He was then with friends during the sighting that lasted approximately seven minutes. Together with friends, he watched the UFO hovered in the night sky very brightly.
As they tried to get abetter position to see what was just transpired, they noticed two smaller lights below the larger UFO.
The strange UFO lights hovered on the same spot for few minutes before one of the smaller objects disappeared. The other smaller UFO also vanished moments later, leaving only the unidentified flying object with a large bright light in the sky.
The remaining lone UFO then started to drift in the sky towards west until it also vanished, according to the reporting witness.
Because they were apparently overwhelmed on their first sighting, it did not come to their mind to record it on video.
They saw the same UFO about an hour later and this time, the witness managed to record two videos of the sighting that lasted approximately five minutes, but, as the witness admitted, they were of poor quality.
Fortunately, the witness was able to record a better video on the third sighting. The third clip shows an airplane flying with blinking navigational lights at first and then the mysterious UFO becomes visible. The strange object appears to fly at a lower altitude than the plane as it moves slowly westward.
As he tried to zoom in the object, the orb UFO changed into a doughnut-shaped circle. After the UFO had disappeared, it reappeared again after 30 minutes and accompanied this time by another UFO. But, he missed recording the sighting on video and did not give any reason in his report.
Jupiter's Wild North Pole, Southern Auroras Photographed for 1st Time
Jupiter's Wild North Pole, Southern Auroras Photographed for 1st Time
By Mike Wall, Space.com Senior Writer
NASA's Juno spacecraft has beamed home the first-ever photos of Jupiter's north pole, and scientists can hardly believe their eyes.
Juno captured the images on Aug. 27, when the probe skimmed just 2,600 miles (4,200 kilometers) above Jupiter's cloud tops during the first of three dozen close flybys of the solar system's largest planet.
"First glimpse of Jupiter's north pole, and it looks like nothing we have seen or imagined before," Juno principal investigator Scott Bolton, of the Southwest Research Institute in San Antonio, said in a statement. [Photos: NASA's Juno Mission to Jupiter]
"It's bluer in color up there than other parts of the planet, and there are a lot of storms," Bolton added. "There is no sign of the latitudinal bands or zone and belts that we are used to; this image is hardly recognizable as Jupiter. We're seeing signs that the clouds have shadows, possibly indicating that the clouds are at a higher altitude than other features."
Saturn has a huge hexagonal storm swirling at its north pole. But Jupiter lacks such a vortex, the new photos show.
"There is nothing on Jupiter that anywhere near resembles that," Bolton said. "The largest planet in our solar system is truly unique. We have 36 more flybys to study just how unique it really is."
The $1.1 billion Juno mission launched in August 2011 and reached Jupiternearly five years later, on July 4 of this year. But Juno's instruments were turned off on this latter date, because mission team members wanted to focus on executing the make-or-break, 35-minute orbit-insertion burn.
So the Aug. 27 approach marked the first opportunity for the Juno team to photograph Jupiter up close and make detailed measurements with its suite of eight science instruments. (The spacecraft is currently in a highly elliptical, 54-day orbit around the planet.)
One of these instruments, the Jovian Infrared Auroral Mapper (JIRAM), captured views of Jupiter's north and south poles in infrared light, revealing hot spots that had never been seen before, mission scientists said.
Like Earth, Jupiter has auroras — dramatic light displays that dance above the planet's north and south polar regions. JIRAM got unprecedented looks at the powerful Jovian southern aurora, Juno team members said.
"We were amazed to see it for the first time," JIRAM co-investigator Alberto Adriani, of the Istituto di Astrofisica e Planetologia Spaziali (Institute of Astrophysics and Space Planetology) in Rome, said in the same statement.
"No other instruments, both from Earth or space, have been able to see the southern aurora," he added. "Now, with JIRAM, we see that it appears to be very bright and well-structured. The high level of detail in the images will tell us more about the aurora's morphology and dynamics."
Juno also managed to "hear" Jupiter's auroras, using the spacecraft's Radio/Plasma Wave Experiment (also known as Waves).
Spectacular aurora lights up Jupiter’s North Pole

"Waves detected the signature emissions of the energetic particles that generate the massive auroras which encircle Jupiter's north pole," said Waves co-investigator Bill Kurth, a research scientist in the Department of Physics and Astronomy at the University of Iowa. "These emissions are the strongest in the solar system. Now we are going to try to figure out where the electrons come from that are generating them."
Next month, Juno is scheduled to perform another engine burn that will shift the probe into a 14-day-long orbit. The spacecraft will continue gathering data — especially during its close flybys over the planet's poles — before ending its mission with an intentional death dive into Jupiter's atmosphere in February 2018.
Juno's observations should help scientists better understand Jupiter's composition and structure, including whether the giant planet harbors a core of heavy elements. This information should, in turn, shed light on the formation of Jupiter, the solar system and planetary systems in general, NASA officials have said.
Reference: Van Allen Radiation Belts: Facts & Findings
Van Allen Radiation Belts: Facts & Findings
By Elizabeth Howell, Space.com Contributor
Earth is surrounded by giant donut-shaped swaths of magnetically trapped, highly energetic charged particles. These radiation belts were discovered in 1958 by the United States' first satellite, Explorer 1. The discovery was led by James Van Allen at the University of Iowa, which eventually caused the belts to be named after him.
Van Allen's experiment on Explorer 1, which launched Jan. 31, 1958, had a simple cosmic ray experiment consisting of a Geiger counter (a device that detects radiation) and a tape recorder. Follow-up experiments on three other missions in 1958 — Explorer 3, Explorer 4 and Pioneer 3 — established that there were two belts of radiation circling the Earth.
This simple picture of the radiation belts persisted for decades until 2012, when a pair of probes was launched to study them in detail. This was the first time that two spacecraft simultaneously studied the radiation belts, trading information with each other to build a bigger picture.
Early probe findings
Part of the interest in the Van Allen belts comes from where they are located. It is known that the belts can swell when the sun becomes more active. Before the probes launched, scientists thought the inner belt was relatively stable, but when it did expand its influence extended over the orbit of the International Space Station and several satellites. The outer belt fluctuated more often.
The Van Allen Probes (formerly known as the Radiation Belt Storm probes)have several scientific goals, including discovering how the particles — ions and electrons — in the belts are accelerated and transported, how electrons are lost and how the belts change during geomagnetic storms. The mission was planned to last two years, but as of August 2016 the probes were still operating at double the expected mission lifetime.
Usually scientists take a few months to calibrate their instruments, but a team with the Relativistic Electron Proton Telescope asked that their instrument be turned on almost immediately (three days after launch). Their reasoning was they wanted to compare observations before another mission, SAMPEX (Solar, Anomalous, and Magnetospheric Particle Explorer), de-orbited and entered Earth's atmosphere.
"It was a lucky decision," NASA said in February 2013, noting that a solar storm had already caused the radiation belts to swell as soon as the instrument was turned on. "Then something happened no one had ever seen before: the particles settled into a new configuration, showing an extra, third belt extending out into space," the agency added. "Within mere days of launch, the Van Allen Probes showed scientists something that would require rewriting textbooks."
Protective shield
Data gathered by the probes also showed that the radiation belts shield Earthfrom high-energy particles. "The barrier for the ultrafast electrons is a remarkable feature of the belts," study lead author Dan Baker, of the University of Colorado in Boulder, said in a statement.
"We're able to study it for the first time, because we never had such accurate measurements of these high-energy electrons before." [Gallery: NASA's Van Allen Probes]
Complex configuration
This new information helped scientists model the belts' changes. But there was more information to come. In January 2016, scientists revealed that the shape of the belts depends on what type of electron is being studied. This means the two belts are much more complex; depending on what is being observed, they can be a single belt, two separate belts or just an outer belt (with no inner belt at all.)
"The researchers found that the inner belt — the smaller belt in the classic picture of the belts — is much larger than the outer belt when observing electrons with low energies, while the outer belt is larger when observing electrons at higher energies," NASA wrote at the time. "At the very highest energies, the inner belt structure is missing completely. So, depending on what one focuses on, the radiation belts can appear to have very different structures simultaneously."
What is still poorly understood, however, is what happens when particles from the sun hit the belts during a geomagnetic storm. It is known that the number of electrons in the belts changes, either decreasing or increasing depending on the situation. Also, the belts eventually return to their normal shape after the storm passes. NASA said it isn't clear what kind of storm will cause a specific type of belt configuration. Also, the agency noted, any previous observations were done only with electrons at a few energy levels. More work needs to be done.
Luckily, scientists got the chance to observe a storm up close in March 2015, when one of the Van Allen probes happened to be situated inside the "right" spot in Earth's magnetic field to see an interplanetary shock. NASA describes such shocks as similar to when a tsunami is triggered by an earthquake; in this case, a coronal mass ejection of charged particles from the sun creates a shock in specific areas of the belts.
"The spacecraft measured a sudden pulse of electrons energized to extreme speeds — nearly as fast as the speed of light — as the shock slammed the outer radiation belt," NASA wrote at the time. "This population of electrons was short-lived, and their energy dissipated within minutes. But five days later, long after other processes from the storm had died down, the Van Allen probes detected an increased number of even higher energy electrons. Such an increase so much later is a testament to the unique energization processes following the storm."
Designing better spacecraft
The Van Allen Probes are specially radiation-hardened to withstand the intense environment of the belts. Some spacecraft, however, are more vulnerable — especially when a solar storm hits. At worst, spacecraft can short out due to an electrical overload. Communications can also be disrupted. Fortunately, sometimes instruments can be turned on or off on a spacecraft during a solar storm.
Radiation, of course, also poses a human risk. Astronauts are subject to lifetime radiation limits from their time in space, to reduce any risk of cancer. Since only a few dozen people have spent six months or longer in space, however, it will take decades to understand the long-term effects of radiation on humans.
The astronauts on the ISS do not regularly spend time inside the belts, but from time to time solar storms expand the belts to the orbit of the space station. In the 1960s, several Apollo crews went through the Van Allen belts on their way to and from the moon. Their time in that radiation-intensive region, however, was very short, in part because the trajectory was designed to pass through the thinnest known parts. With more study, astronauts can be better protected for long-term stays in Earth orbit.
"We study radiation belts because they pose a hazard to spacecraft and astronauts," said David Sibeck, the Van Allen Probes mission scientist at NASA's Goddard Space Flight Center in Maryland, in an August 2016 NASA statement. "If you knew how bad the radiation could get, you would build a better spacecraft to accommodate that."
That recently detected 'alien signal' is actually just a terrestrial disturbance

That recently detected 'alien signal' is actually just a terrestrial disturbance
The call came from inside the house.
Researchers working with the Ratan-600 radio telescope in Russia have confirmed that the reported 'strange signal' that's been making headlines lately is nothing more than a terrestrial disturbance caused by a Soviet satellite.
The signal was originally detected back in May 2015, and was thought to be coming from the star HD 164595. The fact that it was so unusually strong hinted at the fact that something odd was going on here. But the only strange thing here is that the signal wasn't coming from space at all - it was coming from Earth.
"We indeed, discovered an unusual signal. However, an additional check showed that it was emanating from a Soviet military satellite, which had not been entered into any of the catalogues of celestial bodies," team member Alexander Ipatov, from the Russian Academy of Sciences, told the Russian news agency TASS.
In case you missed it, a few days ago, word of an intriguing signal started to make headlines across the world after popular astronomy writer Paul Gilster wrote about it on his blog Centauri Dreams.
The signal, which was supposedly detected last year by the Ratan-600 telescope in Russia, was extremely strong, with a 2.7 centimetre (1.06-inch) wavelength with an 11 GHz frequency, which is comparable to a digital TV signal.
The find was made all the more interesting by the fact that HD 164595 - the star the signal appeared to be coming from - is a lot like our Sun.
HD 164595 is only 1 percent lighter than the Sun, 100 million years younger, has a similar temperature, and is even composed of the same elements.
All of this added up to a whole lot of hype. So much so, that researchers from the Search for Extraterrestrial Intelligence (SETI) observed the area, which lies in the constellation Hercules some 94 light-years away, using the Allen Telescope Array, but they didn’t find anything interesting.
Now the researchers who originally found the signal have set the record straight by announcing that it was nothing more than a terrestrial disturbance.
"There have been no scientific results within the framework of this research so far. Some time ago, in the spring of this year, an unusual signal was received but its analysis showed that it was most likely a terrestrial disturbance."
This means that the signal was coming from a Soviet satellite and somehow got mixed up in their findings, which would explain its unusual strength.
Right now, the team says they're going to be preparing an official statement thatwill be sent out shortly.
While the news is definitely a bummer for those of us who dream of finding intelligent life somewhere in the Universe, it’s pretty cool to see how the scientific community pulls together almost overnight when an intriguing signal is picked up.
Hopefully, with so many astronomical organisations working together around the world, if there are signals from intelligent life beaming out across the galaxy or beyond, we'll be equipped to find them. But today is not that day.
Heel vaak zijn de opnames die mensen maken van vreemde vliegende objecten in onze lucht vaag en onduidelijk.
Maar soms komen er beelden tevoorschijn die thuis horen bij de mooiste opnames van het jaar zoals de hiernavolgende.
De volgende UFO waarneming is gedaan door een man op 12 augustus 2016 in de plaats Bayonne in de Amerikaanse staat New Jersey.
Er was net een felle bui geweest en de man stapte naar buiten om wat foto’s te nemen van de mooie wolkenluchten.
Wanneer hij later de foto’s op zijn computer zet, ontdekt hij in één ervan een grijze streep.
Maar, wanneer je die grijze streep wat verder uitvergroot dan zie je iets dat misschien wel bij de mooiste UFO opnames van dit jaar hoort.
Een prachtige retro UFO, de klassieke vliegende schotel, waarbij je zelfs de ramen ziet.
Zelden zie je opnames die zo duidelijk zijn als de bovenstaande.
Scott Waring van Ufo Sightings Daily heeft de kleuren wat verbeterd en dan ontstaat het volgende.
Deze UFO in New Jersey lijkt heel veel op degene die Scott heeft ontdekt in 2012 op Google Earth.
De afbeelding is genomen bij Kaap de Goede Hoop en laat ook dezelfde mooie retro vorm zien. Maar, na de publicatie van deze afbeelding duurde het niet lang voordat deze wasweg gepoetst door Google.
UFO’s bestaan tenslotte niet, dus als ze wel ergens voorkomen, dan moeten we heel snel maatregelen nemen om ervoor te zorgen dat ze dan verdwijnen.
Interstellar Space Travel: 7 Futuristic Spacecraft To Explore the Cosmos
Interstellar Space Travel: 7 Futuristic Spacecraft To Explore the Cosmos

INTRO. To the stars
Astronomers recently announced strong evidence of an Earth-like alien planet around Proxima Centauri, the star closest to our sun, making it the closest exoplanet found to date. Though the star system is our cosmic neighbor, it is still located 4.2 light-years, or 25 trillion miles, away from Earth. At such distances, could we ever visit the newfound planet?
Even the nearest stars would takes tens of thousands of years to reach using conventional spacecraft, such as the robotic probes being used now to explore the solar system. These spacecraft are driven by a combination of chemical rockets, low-thrust ion drives and gravity-assisted trajectories — including so-called "slingshot maneuvers" around the sun or large planets that give them a big burst of speed.
But if we're going to travel beyond our solar system, we're going to need something a little faster than that — perhaps something like the giant Project Daedalus fusion rocket, shown here to scale with NASA’s Saturn V rocket in an illustration by graphical engineer and space artist Adrian Mann, whose work is featured in this countdown of futuristic space technologies. Here are seven ways that robots, or even human explorers, could visit the Proxima Centauri system or other cosmic neighborhoods.

1. Project Daedalus
Project Daedalus is a concept design for an interstellar probe, developed in the 1970s by a group of technical specialists for the British Interplanetary Society. The target destination was Barnard’s Star — a red dwarf about 6 light-years away, in many ways similar to Proxima Centauri, where astronomers now report they have found signs of apotentially habitable planet. When Project Daedalus was conceived, some astronomers thought a gas giant planet might be in orbit around Barnard's Star, but since then, no planets have been found in the star system.
The result of the five-year project was the design of the Daedalus spacecraft, a two-stage, 54,000-ton nuclear rocket that would boost a 400-ton robotic probe to around 12 percent of the speed of light. This would enable the probe to make the 6-light-year journey to Barnard’s Star in around 50 years.
The rockets of the Daedalus spacecraft would be powered by nuclear fusion, using electron beams to detonate a stream of pellets of fuel such as helium-3, which could be mined from the surface of the moon. Even so, the engines would consume tens of thousands of tons of fuel to get the spacecraft up to its top speed in about 4 years — and because there wouldn’t be any fuel left to slow down, the end result of the 50-year journey would be just a 70-hour flyby of the destination system, before the spacecraft speeds past into interstellar space.
The Daedalus would be much too large to lift off from the Earth’s surface, so it would have to be built in orbit, which means spacecraft like this couldn’t be built without a capacity for construction in space that doesn’t exist today, said space scientist Ian Crawford, a professor of planetary science and astrobiology at Birkbeck College in the United Kingdom.
While Crawford thinks the science behind the Project Daedalus concept is better understood now than when the spacecraft was designed, he said the immense cost and enormous technical challenges likely mean it would be more than 100 years before something like the Daedalus sets out for the stars.µ

2. Project Icarus
The Project Daedalus concepts from the 1970s are the inspiration for Project Icarus, an ongoing joint project by the British Interplanetary Society and the Icarus Interstellar organization, an international network of scientists, engineers and enthusiasts who hope to develop the capabilities for interstellar spaceflight by the year 2100.
Project Icarus is designed to reach any star within 22 light-years of Earth that has a potentially habitable exoplanet, meaning if a planet is confirmed around Proxima Centauri, it could become a target destination.
Project Icarus aims to update the Daedalus design with new technologies and ideas. Among the refinements proposed are fusion rocket engines that use a different nuclear fuel, which would be detonated by lasers instead of electron beams — a technology that could draw from recent advances in laser-ignition fusion at the National Ignition Facility at Lawrence Livermore National Laboratory in California, Crawford said.
The Icarus probe could also be smaller than the 400-ton probe envisioned for Project Daedalus, thanks to advances in electronic miniaturization and robotics, and future nanotechnologies — which would mean the spacecraft would need to carry less fuel to reach its full speed.

3. Light sail
Our best bet for interstellar travel may be to not use a rocket at all, Crawford said. Light sails, which use the pressure of light to propel a payload, are already being considered for interplanetary space probes, and in 2010 Japan’s experimental IKAROS spacecraft successfully used its 60-foot-wide (20 meters) light sail to maneuver during a six-month journey to Venus.
But although light sails driven by sunlight are already an effective way to explore the solar system, they are not fast enough to cover interstellar distances in a reasonable amount of time.
Crawford said the answer may be to use powerful lasers to push the light sail to very high speeds with bursts of light at the start of the journey, until the spacecraft is too far from the laser source to gain more thrust from the light beam.
Since the driving lasers would be built on Earth or in orbit, interstellar light-sail spacecraft would not need to carry fuel for the journey, and so the mass of the spacecraft could be kept small.
Laser-driven light sail spacecraft are the basis of the Breakthrough Starshot project that was announced this year by investor Yuri Milner and physicist Stephen Hawking. The project aims to build a working prototype by 2036 at a final mission cost of around $10 billion dollars.
The project envisages a swarm of around 1,000 stamp-size "StarChip" spacecraft, each weighing a few grams and attached to a light sail measuring 13 feet (4 m) across, which would be deployed from a "mothership" in orbit before being accelerated by ground-based lasers to speeds of around 15 to 20 percent the speed of light.
This would allow the spacecraft to make the 4-light-year journey to the Alpha Centauri system — a triple-star system that includes the star Proxima Centauri and its possible planet — in between 20 and 30 years.
The concepts behind the Breakthrough Starshot project have been studied by Philip Lubin, a professor of cosmology at the University of California, Santa Barbara, who says the biggest challenge remaining is to create sufficiently powerful lasers to drive the light sail spacecraft.

4. Bussard ramjet
The Bussard Ramjet concept, proposed by physicist Robert Bussard in 1960, combines the high thrust of fusion rockets with the low fuel requirements of light sails.
Instead of carrying its own fuel, a Bussard Ramjet would scoop up the very thin traces of gas and dust found in interstellar space, known as the Interstellar Medium, using a vast funnel-shaped electromagnetic field that extends for thousands of miles in front of the spacecraft.
Hydrogen from the Interstellar Medium would then be compressed and used as fuel in a fusion rocket at the rear of the spacecraft that drives it forward.
In theory, a spacecraft driven by a Bussard Ramjet could continue to accelerate as long as there is enough interstellar gas in its path to provide enough thrust, and could reach a high fraction of the speed of light.
As a result, the venerable Bussard has seen long and honorable service in many works of science fiction, notably Larry Niven’s "Known Space" series of novels and short stories, including the "Ringworld" books; and the 1970 Poul Anderson novel "Tau-Zero" (Doubleday, 1970), in which an interstellar crew push their stricken Bussard spacecraft to relativistic speeds to avoid destruction.
Unfortunately, the Interstellar Medium around our solar system and the nearby stars is especially thin, and scientist have calculated that there’s just not enough hydrogen there to fuel a Bussard Ramjet. "It's not the ideal part of the galaxy," Crawford said.
But he explained that several ideas have been proposed to get around this limitation, including a concept known as a “Ram Augmented Stellar Rocket”, which uses collected matter as reaction mass to drive the spacecraft forward, using energy beamed to it by a laser; and an "Interstellar Runway," which would use deposits of fuel positioned in advance in the path of an accelerating Bussard spacecraft.

5. Antimatter rocket & black hole drive
Beyond light sails, giant lasers and fusion rockets, a few even more exotic options for interstellar travel have been proposed, such as rockets powered by the extremely violent (and supremely efficient) annihilation reaction of matter and antimatter.
"Antimatter would be an excellent rocket fuel, because its energy density is so high," Crawford said. "But, of course it doesn't exist in nature, we have to make it. And it's very difficult and expensive to make, and very dangerous once you've made it — so who knows whether it could ever be used as a rocket fuel?"
Another proposal for using exotic physics to drive a spacecraft is the "Schwarzschild Kugelblitz" drive, which would use a microscopic, artificial black hole contained within its engines as its power source.
One idea for a ship equipped with the so-called "SK Drive," shown above, would trap Hawking radiation from the rapid and extremely violent decay of the tiny black hole, and convert it to energy that can be used it to propel the spacecraft.
Each of the artificial black holes would only survive for a few years, so new black holes would need to be created on demand, possibly by compressing pellets of matter with gamma-ray lasers.
According to a 2009 research paper, an SK-drive starship powered by a microscopic black hole with the mass of a modern supertanker could accelerate to 10 percent of the speed of light within 20 days. The black hole would last around 3.5 years before it decayed entirely, and would output more than 160 petawatts, or 160 quadrillion watts, of power in its lifetime.

6. Human "Slow Boats"
Even with super-fast rockets traveling at speeds of 10 percent or more of the speed of light, it would take many human lifetimes to reach all but the very nearest stars. And although Crawford is an advocate of human exploration of the solar system, he said that interstellar distances are too vast to make a human voyage conceivable within the next few hundred years.
"I think humans can explore the planets more effectively than robots, and I also think there are cultural reasons for sending humans into space, to broaden our range of experiences and enrich human culture," he said. "Now, it’s true that all of that would apply on the interstellar scale as well — it’s just that the distances are so large and the technical difficulties so great that advocating it at this stage is almost inconceivable."
Even so, several ideas exist for what are known as "Slow Boat" concepts that might one day take humans to the stars, including:
Sleeper Ships, in which human crewmembers are kept in a state of "deep sleep" or "suspended animation" for the duration of the very long voyage. This idea has featured in several science fiction movies, including Stanley Kubrick’s "2001: A Space Odyssey" made in 1969, Ridley Scott's "Alien" in 1979 and James Cameron's "Avatar" in 2009.
World Ships, also known as generation ships or interstellar arks, would be giant self-contained space habitats carrying large populations of humans and other species from Earth on a relatively leisurely journey to colonize exoplanets — journeys that would take many centuries to complete. Entire generations would live and die during the voyage, and only the descendants of the original population would arrive at the destination.
Embryo Shipswould send cryogenically frozen embryonic humans, instead of sleeping or living humans, to a distant colony planet, where they would be "hatched out" and educated on their mission by a crew of protective robots.

7. Faster than light?
Wherever astronomers look in the universe, the Theory of Relativity holds fast. As Albert Einstein showed, it's not possible to accelerate a mass to the speed of light in space, nor past it.
But Einstein's equations may yet hold a few tricks that could someday let science do an end-run around the known laws of physics and achieve faster-than-light (FTL) travel — a Holy Grail for generations of science fiction fans.
The best known scientific concept for FTL travel is the Alcubierre drive, proposed by theoretical physicist Miguel Alcubierre in 1994.
The proposed drive operates by using intense gravitational forces, generated by two rotating rings of dense exotic matter, to shrink the physical dimensions of space in front of the spacecraft while expanding the space behind it, at a rate that could appear to exceed the speed of light.
In Alcubierre's proposal, which requires a type of exotic matter for the rings that is not known to exist, the spacecraft inside the "warp bubble" created by the drive would never travel faster than light in its local space, and so would not violate the laws of relativity.
Other speculative ideas for FTL travel include using trans-dimensional wormholes — also theoretically possible, but not known to exist — to travel between entangled but distant regions of space; or to daringly skim the edges of a large, spinning black hole, as depicted in Christopher Nolan’s 2014 movie "Interstellar."
But Crawford notes that the concept of faster-than-light travel is rife with unknowns and apparent contradictions, such as violating the principle of causality, in which events are caused by other events that happened earlier in time, and not the other way around. So, it's likely the proposals would prove impossible, even if they were technologically feasible to attempt.
"I don't want to sound overly pessimistic, because I can see huge benefits of being able to travel to the stars, but the laws of physics are the laws of physics, and it is going to be really difficult," Crawford said.
Engineers Are 3D Printing Coral Reefs to Help Save Our Oceans
Engineers Are 3D Printing Coral Reefs to Help Save Our Oceans
BARTHOLOMEW COOKE
IN BRIEF
One island is turning to 3D printing to help preserve the region's fragile coral reefs. The island's Harbour Village Beach Club has teamed up with ocean preservationist Fabien Cousteau to bring the 3D printing technology to our waters.
Some 3D printing trends may come and go, but this latest effort—much like Fred the tortoise’s new shell—is sure to stick for life. The trend we’re referring to is 3D-printed corals.
Coral reefs, as we all learned in science class, are remarkably important. They contain the most diverse ecosystems on Earth, and they also protect coastlines from waves and tropical storms, among other things. Sadly, coral reefs are in danger of disappearing, thanks to the combination of diseases, and damage that is caused by climate change, pollution, and other human acitivies
Such is the case in the Caribbean Island of Bonaire, which is turning to additive manufacturing for help to preserve the region’s fragile coral reefs.
3D-PRINTED REEFS
The island’s Harbour Village Beach Club has teamed up with ocean preservationist Fabien Cousteau to bring the 3D printing technology to Bonaire’s coasts. Cousteau is the grandson of the late oceanographer Jacques Cousteau, who made scuba diving possible.
For this project, the younger Cousteau will help the island plan and print pieces of artificial coral that will bear the same shape, texture, and even chemical makeup of organic corals to attract floating baby coral polyps and other species that rely on coral reefs for protection, including algae, crabs, and other fish species.
“This technology is less labor-intensive than current coral restoration processes, creating a larger impact in a shorter amount of time,” Cousteau told the Caribbean Journal.
This isn’t the first time that 3D printing has been used to save the threatened coral reefs. In 2012, Australian organization Reef Design Lab implanted the first artificial reef using low carbon footprint sandstone material in Bahrain’s Reef Arabia.
“We can achieve a very ‘organic’ appearance, and produce far greater complexity, caves and tunnels compared to traditional moulding techniques—this can translate to greater biodiversity and biomass,” RDL said in its website.
VIDEODe Amerikaanse ruimtevaartorganisatie NASA heeft een primeur te pakken. Ze kon voor het eerst de noordpool van de planeet Jupiter gedetailleerd op foto vastleggen. De afbeeldingen werden genomen door de ruimteverkenner Juno en dit weekend door de NASA vrijgegeven.
"Het lijkt op niks dat we ooit eerder hebben gezien", zegt Scott Bolton van het Southwest Research Institute (Texas). Ook de zuidpool van de gasreus werd vereeuwigd, maar het is vooral de noordpool die de aandacht van de onderzoekers trekt. Ze kleurt immers blauwer dan de rest van het hemellichaam en het is er schijnbaar veel stormachtiger dan verwacht.
De ruimtesonde maakte ook infraroodbeelden van de grootste planeet van ons zonnestelsel. Zo is op een van de foto's het morgenrood op de zuidpool te zien.
Juno stuurde eerder al foto's van Jupiter door naar de aarde, maar de afbeeldingen die de NASA onlangs op haar website plaatste, zijn veel scherper.
De verkenner vloog vorige week 'dicht bij' de planeet op een afstand van circa 4.000 kilometer. Er volgen de komende maanden nog tientallen vluchten rond de gasreus om meer data te verzamelen. In 2018 is de missie afgelopen en zal Juno vergaan in de atmosfeer.
Ruimtesonde Dawn van de Amerikaanse ruimtevaartorganisatie NASA bestudeerde de berg op Ceres de afgelopen maanden. De vulkaan is half zo hoog als de Mount Everest. De laatste uitbarsting vond vermoedelijk honderden miljoenen jaren geleden plaats.
"Het is onwijs cool en onverwacht", zei Christopher Russell van de University of California vandaag. Ceres stond ooit te boek als een volwaardige planeet, maar werd later gedegradeerd tot asteroïde. Tegenwoordig valt Ceres in de categorie dwergplaneet, net als Pluto.
Ruimtesonde Dawn is de eerste die de dwergplaneet van dichtbij observeert. De sonde cirkelt als sinds maart 2015 rond Ceres.
Deze keer zijn ze er honderd procent zeker van dat ze het bewijs hebben dat we niet alleen zijn in het heelal. Ufospotters hebben op YouTube een filmpje gedeeld waarop het internationaal ruimtestation ISS te zien is. Op de beelden is plots twee keer een lichtgevend object waar te nemen dat passeert.
De beelden zouden afkomstig zijn van de NASA volgens StreetCap1, de ufojagers die het filmpje hebben gedeeld. Het ruimtestation is immers 24 uur per dag te volgen via een livefeed van de ruimtevaartorganisatie. Je kan de Russische Progress Capsule zien, die zich aan het ISS heeft vastgemaakt voor bevoorrading. Achter de capsule is tot twee keer toe een lichtbol waar te nemen.
Volgens Scott Warring van de website UFO Sightings Daily gaat het om het ultieme bewijs dat buitenaardse wezens het ruimtestation in de gaten houden. Onder het filmpje - dat intussen al 15.000 keer werd bekeken in enkele dagen tijd - zijn nog meer enthousiaste commentaren te lezen. En af en toe een kritische noot van iemand die er niets van gelooft en de spotters een dokter aanraadt.

(video)NICARAGUAN WOMAN CLAIMS THAT SHE WAS KIDNAPPED BY GOBLINS!
Everyone knows all about the "Alien abduction" phenomena and there have been countless stories regarding that topic. People who have been abducted by short little green men or even other humanoid looking creatures.
However some bizarre abductions aren't just exclusive to extraterrestrial origin. One account by a woman living in a village near Monte Escuro, Nicaragua, claimed being kidnapped by evil goblin creatures when she was a little girl. She was in a cave for six days before her family came to rescue her with the aid from a witch.
Locals tell of many supernatural and strange creatures living on the hills surrounding that region. Creatures like goblins and fairies are said to be common and are sighted occasionally.
Many accounts of similar "little people" are spoken around many of our world's cultures and legends. Who knows, perhaps the "Little Green Men" from space have always been little magical goblins.
AMAZING! STRANGE ALIEN CREATURE LURKING CAUGHT ON CAMERA!
AMAZING! STRANGE ALIEN CREATURE LURKING CAUGHT ON CAMERA!
On the depths of our world's oceans or even on the smallest of lakes we can spot some terrifying things. From there in the dark waters beyond the penumbra, lurks mysterious creatures that mankind will barely witness on their lifetime.
We know very well of the Lochness monster tale, the idea of a giant sea dragon or an aquatic dinosaur hiding somewhere on the lake is mindblowing. Or the stories of colossal Krakens that terrified our ancestors when journeying through the seas.
There are also conspiracy theories regarding Aliens who seem to roam the depths on their USO's (unidentified submerged objects) and have established underwater bases and cities.
A lot of myths and legends concerning our world's mysterious aquatic regions have been around since ever, however, there's little evidence to prove any of this to be true.
But recently a man from Leyland, Lancashire, has caught something surreal on camera.
Studie: Buitenaardse groepen houden aarde mogelijk bewust in isolement
Studie: Buitenaardse groepen houden aarde mogelijk bewust in isolement
Er is een nieuwe studie verschenen waarin wordt gespeeld met het idee dat aliens ons er bewust van weerhouden om contact met ze op te nemen.
Volgens de dierentuinhypothese bestaat er superintelligent buitenaards leven, maar kiest het ervoor om geen contact met het leven op aarde op te nemen om ons ongemerkt te bestuderen of om de menselijke beschaving zo de kans te geven zich te ontwikkelen.
Dergelijke ideeën zijn het meest aannemelijk als er een universele entiteit zou bestaan die zijn wil aan andere buitenaardse beschavingen kan opleggen. Volgens de hypothese is een voldoende geavanceerde beschaving in staat om de handhaving van regels effectiever af te dwingen dan de mensheid gewoon is.
Strijdende groepen
Astrofysicus Duncan H. Forgan van de Universiteit van St Andrews heeft een model gebruikt waaruit blijkt dat beschavingen in zo’n scenario meer geneigd zijn om groepjes te vormen in plaats van één grote galactische club.
Als alle beschavingen ongeveer tegelijkertijd zijn ontstaan en al meer dan een miljoen jaar bestaan, dan zou zo’n club volgens Forgan kunnen bestaan. Het is zijns inziens waarschijnlijker dat er meerdere strijdende groepen beschavingen zijn die het niet met elkaar eens kunnen worden over een universeel beleid.
Impasse doorbreken
“Het is goed mogelijk dat de aarde zich bevindt in een deel van de ruimte dat wordt bezet door een conservatieve groep die geen contact wil,” valt te lezen in zijn paper. “Nu we steeds beter in staat zijn om onbewuste signalen van zowel bestaande als vergane beschavingen te kunnen detecteren, zouden we deze impasse moeten kunnen doorbreken.”

Family spot UFO while walking on Yorkshire, England, Sept 2016, UFO Sighting News
Date of sighting: Sept 2016 Location of sighting: Yorkshire, England News source:
https://www.thesun.co.uk/news/1721172/family-spot-ufo-shaped-like-star-treks-starship-enterprise-while-walking-on-yorkshire-moors/ Here is a great photo of a UFO with two long appendages on its right and left size. Some say it looks like the Enterprise, I think it looks like a sideways disk. England is however one of two testing grounds for secret alien tech from the USAF. So, is this ours or is it alien? Scott C. Waring www.ufosightingsdaily.com News states: A FAMILY out walking on a Yorkshire moorland claim to have captured a Star Trek-shaped UFO flying overhead. The dark grey object, which appears to have a halo around it, was snapped by Nicole Smith, 19, on her smartphone during a family day out to Bronte waterfalls, in West Yorkshire. She was with her parents Catherine and Shane at the time and was shocked when she discovered the UFO on one of her photos. Her mum Catherine, 49, from Normanton, said: “We went for a day out in Haworth and decided to drive to the moor and parked near a footpath leading to Bronte waterfalls.
“It was a good two and a half mile walk from where the car was parked. “My daughter was taking random pictures of the sheep and scenery on our way back from the falls. It was around 5.30pm when she took the picture on her mobile phone. “It was only when we were on our way home she was scanning through the photos she had taken, she noticed the object in the picture.” The picture has been studied by an American optical physicist formerly employed by the US Navy. Dr Bruce Maccabee, who is now a leading Ufologist, said: “I’m not aware of anything that looks like this. The image is too small for good resolution. “It was not seen at the time so no information on distance. It might be some sort of insect within ten feet from the camera.”
UFO Fleet Caught Passing Over A Suspected Alien Base
UFO Fleet Caught Passing Over A Suspected Alien Base
Incredible footage of multiple massive UFOs has emerged recently – bringing the theory of an alien base anew. A suspected alien spaceship moves through the clouds over the Yellowstone National Park in the U.S. The space vessel is believed to be over 100 meters across.
A gigantic super-volcano is a notable natural structure in the Yellowstone National Park. While staying dormant for 70,000 years, a potential eruption of this massive volcano could kill 90,000 people and spark a nuclear winter, experts have warned.
Flying saucers were seen in a live camera observing the park. YouTube user Jeanette Forestershared the video to the video sharing site. She regularly posts short videos of the park, but this is the first time she posted a clip of her UFO sighting, which she describes as once in a lifetime.
Many space alien enthusiasts believe the U.S. knows about an active alien base or bases in the Yellowstone Park because the government allotted 3,468 miles of land for the park.
It doesn't take much to convince people that they've seen an experimental missile or a UFO. A funny-looking cloud or an exceptionally bright planet will usually do the trick. Here, our top 7 things that drive space-related hoaxes.

7. Lightning
Mysterious UFO sightings may go hand-in-hand with a natural weather phenomenon known as sprites flashes high in the atmosphere triggered by thunderstorms. Sprites suddenly appear when lightning from thunderstorms excites the electric field above the storm, producing dancing flashes of bright light.
Sprites can take the form of fast-paced balls of electricity, although they can also form streaks or tendrils. "Winter sprites" are common in the northern hemisphere during winter months.
In December 2009, a spectacular spiral light show appeared in the sky above northern Norway: A giant spiral, with a green-blue beam of light shooting from its center, lit up the sky in a raindrop-ripple effect pattern.
It looked like a wormhole to another dimension, but it turned out that the lights were caused by a Russian missile that failed just after launch, according to Russia's defense ministry. The botched Bulava ballistic test missile spun out of control, thus creating the mysterious rotating spiral effect.
5. Weird Cloud Formations
Balloons in the Sky UFO Test
UFO SIGHTING OR BALLOON? AN EXAMPLE OF MISIDENTIFYING A BALLOON FOR A UFO
Last October, footage of a giant halo in an overcast sky over Moscow surfaced on YouTube. The video had everything needed to ignite UFO rumors. It's grainy. At one point, a dark pointy object appears to bolt out of the ring. There's even a panicked-sounding Russian radio broadcast in the background.
Cool-headed meteorologists were quick to put the story to bed: It was just an optical illusion, the cause of sunlight hitting a cloud disturbed by wind or plane traffic in just the right way. Most likely it was what is known as a hole-punch cloud. These occur in cirrus or cirrostratus clouds, which are often composed of ice crystals and super-cooled water droplets water that is below freezing temperature, but still in liquid form. The physical properties that hold these clouds together are delicate, and when disturbed by a jet plane, wind or even cloud seeding efforts the droplets can freeze instantly or evaporate, the latter of which will form the hole.
3. Venus
The planet Venus often gets mistaken for a UFO. To viewers on Earth, the second planet from the sun appears as a bright light that hangs in the sunset sky, seeming to slowly hover in the twilight as it outshines every star except for the sun. Because Venus orbits the sun inside our own orbit, from our perspective it constantly darts out on the either side of the sun, which people often mistake for a moving UFO.
Here's proof that anything funny-looking in the sky can cause an uproar. This past Monday, most of the U.S. woke up to reports that a mystery missile had launched off the coast of California. The sightings were spurred by video of a condensation trail, or contrail, streaking through clouds lit up by the rising sun. No one could conclusively say what it was at the timeofficials at the Department of Defense reported no scheduled missile launches, NORAD and USNORTHCOM detected no foreign activity and the FAA hadn't cleared any commercial space launches in the area. After a thorough investigation, many experts now believe that the streak was a wait for it a run-of-the-mill jet aircraft contrail that happened to hang around longer than usual. Contrails appear most vivid around sunrise or sunset, and it's not uncommon that one showing up in an unexpected location will generate whispers of a UFO or experimental military aircraft.
Lights in the sky, especially when viewed by pilots, can also cause a stir, but are almost always revealed to be running lights of other aircraft, or flares dropped by weather research craft.

1. Military Experiments
The late 1940s and early 1950s were a great time for spotting UFOs and aliens in New Mexico, primarily because that's where the Air Force was conducting some of its top-secret research. One such program was known as Project Mogul and involved floating microphone-carrying balloons to high altitudes in an attempt to pick up the sound waves generated by Soviet atomic bomb tests. The Air Force has since confirmed that a 1947 crash of one of those balloons created the debris that birthed the Roswell UFO Incident.
Another military experiment provided the bodies for that UFO. In the 1950s, Air Force scientists dropped several dozen anthropomorphic dummies from planes to test new high-altitude parachutes and determine whether the bodies would enter a dangerous spin as they fell. Results from these studies contributed to designs for the parachutes and pressurized suits that fighter jet pilots and early astronauts would wear. The Air Force was more than happy to allow Russian spies to think New Mexicans were a little kooky than to reveal the true military origin of the sightings.

SETI Team Investigating Mysterious Signal from Star 94 Light-Years Away
SETI Team Investigating Mysterious Signal from Star 94 Light-Years Away
By Mike Wall, Space.com Senior Writer
A powerful signal has been spotted coming from the vicinity of a sunlike star, and now astronomers are trying to figure out what it means.
In May 2015, researchers using a radio telescope in Russia detected a candidate SETI (search for extraterrestrial intelligence) signal that seems to originate from HD 164595, a star system that lies about 94 light-years from Earth, the website Centauri Dreams reported over the weekend.
The astronomers have not yet published a study about the detection; they plan to discuss it next month at the 67th International Astronautical Congress (IAC) in Guadalajara, Mexico, according to Centauri Dreams' Paul Gilster, who wrote that one of the team members forwarded him the IAC presentation. [13 Ways to Hunt Intelligent Alien Life]
HD 164595 is known to harbor one planet — a roughly Neptune-mass world that orbits too close to the star to support life as we know it. However, it's possible that other worlds lurk undiscovered in the system, said astronomer Seth Shostak of the SETI Institute in Mountain View, California, who is not part of the detection team.
To be clear: Nobody is claiming that aliens beamed out this signal. But that is one of the possible scenarios at the moment, Shostak told Space.com.
The scientists who made the detection are respected researchers, and the signal is strong enough that it's probably not just random noise, Shostak said. Furthermore, the signal is consistent with something an alien civilization might send out — and if aliens did indeed do it, they are certainly far more advanced than we are, he added.
Based on the received signal's characteristics, aliens would have to generate about 100 billion billion watts of energy to blast it out in all directions. And they'd still have to produce more than 1 trillion watts if they beamed it only to Earth for some reason, Shostak said.
"The first number is hundreds of times more than all the sunlight falling on Earth," he said. "That's a very big energy bill."
The SETI Institute focused the Allen Telescope Array (ATA), a system of radio dishes in Northern California, at HD 164595 Sunday night (Aug. 28) and plans to do so again tonight (Aug. 29), Shostak said. He certainly hopes the ATA finds something that would suggest ET is behind the signal, but he said he suspects there's a more prosaic explanation.
For example, it's possible that interference by an Earth-orbiting satellite or something else close to home is responsible, Shostak said. Indeed, he said that such "terrestrial interference" would be his bet, if we ever do learn what caused the signal.
But, sadly, it's very possible that we'll never know. The Russia-based team apparently observed the HD 164595 system 39 different times and only detected the signal once, Shostak said. If nobody sees it again, it will probably remain a mystery, much like the famous "Wow!" signal of 1977.
