Giant Black UFOs Seen Over Baltimore This Week! Video, UFO Sighting News.
Date of sighting: Oct 13, 2019
Location of sighting: Baltimore, Maryland, USA
Source: MUFON #103972
Here is a video of the most recent UFO sighting. A person saw several black rectangles moving in and out of the clouds over Baltimore. He managed to get some video of the object moving silently. There are no wings, no ropes, no lights of any kind, no windows...nothing that would signify that this is man made. Its very odd to be over such a populated area, especially a busy shipping port. It almost looks as if one of those cargo boxes on the ships had floated away into the sky. I just wish the person had a newer phone, then maybe the video would have been crystal clear.
Scott Waring
Eyewitness states:
While Crossing the Key Bridge in the early morning the witness noticed several cylinder objects with what looked like "Spheres" looping around each one. He states "They went up and down, in and out of the clouds, sometimes disappearing only to reappear again." After watching for about 5 min they all went into the clouds. Several seconds later one dropped back out of the clouds, came down a couple hundred feet and stopped. At this point, I started recording on my phone camera. The witness added "The object hovers for about 1-2 minutes and then slowly moves off the right (NE). With the naked eye, I could see the"White Sphere" going beside and around the crane but the video doesn't show it." The witness said that he stopped filming to pick up his mother who was visiting from New Hampshire, but states "On the way back about 1 hour later we noticed 2 of the 3 crafts, however they were much further away. The second time around I did notice something else... I noticed a very large white sphere. I only viewed it for several seconds before it was obstructed by trees.
Faster-Than-Light Travel Could Explain Mysterious Signals Beaming Through the Cosmos
But don't worry, no laws of physics are being violated.

In a distant corner of the universe, something is traveling faster than light.
No, the laws of physics aren't being violated: It's still true that nothing can travel faster than light in the vacuum of empty space. But when light travels through matter, like interstellar gas or a soup of charged particles, it slow downs, meaning other matter might overtake it. And that may explain the weird symmetry in pulses of some of the most energetic light in the universe, called gamma-ray bursts.
These cryptic bursts — bright flashes of gamma-ray light that come from faraway galaxies — form when massive stars collapse or when ultradense neutron stars collide. These cataclysms send speeding jets of hot, charged plasma zooming through space.
But these signals have an odd symmetry, and the reason they do is still a mystery.
A gamma-ray burst doesn't brighten and dim in one steady peak, but instead in a flickering pattern, said Jon Hakkila, an astrophysicist at the College of Charleston in South Carolina.
Hakkila has worked on this puzzle for years. Now, he and a collaborator have a solution: plasma traveling both slower and faster than the speed of light could explain this flickering pattern, as they report in a paper published Sept. 23 in The Astrophysical Journal. If they're right, it may help us understand what's actually producing these gamma-rays.
"I find it a great step forward," that connects the small scale phenomena in the plasma to our large-scale observations, said Dieter Hartmann, an astrophysicist at Clemson University who was not involved in the study.
In the last few years, Hakkila has found that gamma-ray bursts have small fluctuations in brightness on top of their overall brightening and dimming. If you subtract the overarching brightening and dimming, you're left with a series of smaller peaks — one primary peak with smaller peaks in brightness before and after. And this pattern is strangely symmetric. If you "fold" the pattern over at the main peak and stretch one side, the two sides match remarkably well. In other words, the light pattern of a gamma-ray burst's pulse hints at a set of mirrored events.
"Whatever happened on the front side happened on the back side," Hakkila said. "And the events knew to happen in reverse order."
Though astronomers don't know what causes gamma-ray burst emission at the particle scale, they are fairly sure that it happens when jets of plasma traveling near the speed of light interact with surrounding gases. Hakkila had been trying to come up with explanations for how these situations might make symmetric light pulses when he heard from Robert Nemiroff, an astrophysicist at Michigan Technological University.
Nemiroff was studying what happens when an object travels through a surrounding medium faster than the light it emits, called superluminal motion. In previous research, Nemiroff had found that when such an object goes from traveling slower than light to faster than light, or vice versa, this transition can trigger a phenomenon called relativistic image doubling. Nemiroff wondered whether this could account for the symmetric patterns Hakkila found in gamma-ray burst pulses.
So what exactly is "relativistic image doubling?" Imagine a boat creating ripples as it moves across a lake toward the shore. If the boat travels more slowly than the waves it creates, a person standing on the shore will see the boat's ripples hit the shore in the order that the boat created them. But if the boat travels faster than the waves it creates, the boat will overtake the first wave it creates only to create a new ripple in front of that one and so on. In that way, the new ripples created by the boat will reach the shore sooner than the first waves it created. A person standing on the shore will see the ripples hit the shore in a time-reversed order.
The same idea applies to gamma-ray bursts. If the cause of a gamma-ray burst is traveling faster than the light it emits through the gas and matter surrounding it, we would see the emission pattern in reverse chronological order.
Hakkila and Nemiroff reasoned that this could account for half of a gamma-ray burst's symmetric pulse.
But what if the material was first traveling slower than the speed of light, but then accelerated? What if it started fast and then slowed down? In either case, we might see the emission both in chronological order and reverse chronological order right after one another, making a symmetric pulse pattern like the symmetric peaks observed in gamma-ray bursts.
There are still missing pieces to this puzzle. For one, researchers still don't know what's causing these bursts at the microscopic scale. But this proposed model gives researchers one small clue in the hunt to find the ultimate cause of gamma-ray bursts, Hartmann said.

Two odd flashes next to the Orion ConstellationIt is unknown whether these flashes or signals came from alien spacecraft or not but it is known that huge cigar-shaped UFO flying through space next to the Orion Constellation.
High Altitude Craft With Thrusters Transits The Moon

I've posted this a few years ago, it's pretty incredible footage. I just hadn't seen this video version of it before with the filters.

He's saying the 'thrusters', when they are fired up, they slow the vehicle down. It reminded of something out of control almost, like a vehicle in distress. But that's the thing, who's vehicle is this? be one of ours with thruster technology right? But that's a can of worms in itself. But that's the only that suggests it's ours, nothing else, well aside from the helpless sort of path it's taking, could be alien, who knows. drunk alien? banished alien? human with no real idea how to fly? Who is in that? To fire up the thrusters, or at least what appear to be thrusters, logically it had to be done by someone right? It's certainly not a demon lol. It's a rare capture showing heat and what appears to be in a triangle formation.
Large Orb (UFO) releasing Little Orbs

A UFO filmed by two different men from different locations in Mexico city on May 22nd 2009 appear to show a UFO releasing a large amount of smaller orbs which shoot out at both ends/sides of the UFO.
Remember UFO only means unidentified Flying Objects, im not saying Aliens, but what the Fck is it..?
Most UFOs of the Orb type can usually be explained away as Weather Balloons, Mylar Balloons, Chinese Lanterns, Military Flares and a couple of other things, but how do you explain whats in that video..
.
Ive been Into UFOs and the weird and unexplained since i were 8-9 yrs old and next birthday ill be 60, this video that appears to show a large Orb that releases many smaller Orbs is One video that still intrigues me.
Of course there are some who claim the larger Orb is the Mother Ship and is releasing her fleet of smaller ones, well i dunno bout that, i have entertained that thought but i try not to get carried away.
My only UFO experience around 8 or so yrs ago was of bright orbs drifting over the land, but commin from the ocean, 3 of us fishing in a boat watched for around an hr as orb after orb come up from the sea and drifted over the land.
At times there were only 2 orbs present but at times there were as many as 10.
Now and then a Orb or two would stop as if to let trailing Orbs Catch up, they didnt appear to be controlled by any breeze but rather moved at will, this sighting is the reason i am totally interested in Orbs rather than "Nuts and Bolt" type of UFO to this day.
Here is another odd video that looks as though Orbs are being released from a larger UFO, then they break up in spectacular fashion, only a few Orbs seem to be released but at around 10 seconds you can see a few being released.
Thought id try steer DTV back to the more mysterious and unexplained categories.....![]()
Cassini spacecraft photographed something strange, now appears in Earth's atmosphere?

The YouTuber Galactic Hurricane noticed strange anomalies after studying a great portion of the Cassini project photographs.
Strange spheres seemed to literally stretch within the rings of Saturn. Some did follow the spacecraft and seemed to signal to the Cassini craft.
But the strangest thing happened that on September 25, 2019 when Mauricio Lopez filmed exactly the same object above New York what Galactic Hurricane saw on the Cassini's pictures.
This object is neither a bird nor a conventional plane, it looks more like Starship Enterprise

While filming the moon, witness caught on video this strange flying object.

Alarming discovery: UFO Hunter Films Massive Alien Fleets Orbiting the Sun

NASA Satellites have been observing alien fleets orbiting the sun. Yes, alien fleets!
This is also supported by UFO hunters. The Alien fleets are reported to be flying near the Earth, going towards the sun in tactical formation. This gave heads up to some researchers who have claimed that maybe our sun is a massive stargate which is being used by alien civilisations. This discovery was made by Streetcap1 who is a UFO hunter.
Streetcap1 examined and analysed the images which were captured by the Solar and Heliospheric Observatory Satellite, also known as SOHO. This satellite is in orbit around the L1 gravitational point which is between the sun and earth and is used to look out for important information in the Sun.
The European Space Agency and NASA have worked together on this SOHO project. The UFO hunter, Streetcap1 has claimed that the pictures which are captured by the SOHO satellite show a huge alien fleet of UFO's which are heading towards the sun.
The fleet has been appeared to be travelling in a formation, which would be something like an organised military fleet. Streetcap1 believes that after his experience with UFO fleets, he is in no doubt at all that this fleet is a reality. Another UFO hunter, Scot Warring, has also accredited the efforts of Streetcap1.
Even Scot believes that this is something unique, something he has never seen before. Waring also believes that due to the immense size of the fleet, "something big is about to happen." He believes that the Aliens do know that we, humans, are here, and we exist, but they just ignore us as they are possibly more technologically advanced than us.
Some doubters are still examining the picture in further depth so look for malfunctions like dead pixels and processing errors. But, UFO hunters disagree that there might be any errors present.
Even in the past, there have been many anomalies which seemed to be present near the sun. The following video shows how the Sun is a Stargate:
UFO Fleet Discovered Orbiting the Sun

A UFO fleet has been observed orbiting the Sun in a recently-resurfaced NASA Helioviewer photo. The extraordinary claims about the NASA photograph were made by Terry’s Theories YouTube site. The photo in question bears the timestamp of December 18, 2006. The video says the anomalies could be either be some form of extreme astrobiology or alien technology. The space alien enthusiast suggested they could be flying saucers or even ET entities.
Terry went on to say that space could be home to living creatures of its own just like we have wild animals here on Earth.
He also argued that alien anomalies might be fewer than first imagined. Terry said that they appear to have six UFOs surrounding the Sun in the latest image, but there was probably only one or maybe two. He pointed out the phenomena called ghosting where objects are moving so fast that they give the appearance of being more.
NASA Helioviewer has enabled astronomers to look at the Sun through multiple filters since it started operating in May 1996.
The Sun is the black circle at the center of the photo while everything around it is the solar corona.
NASA’s cutting edge photographic technology allows everyone to observe the solar anomalies in great detail.
Terry added that they had ringed surfaces and a hole in the center.
He noted that they are very hot being so close to the Sun, so they must have some feature protecting them from the extreme heat. He suspected they were refueling.
The by-product of the Sun is helium-3, which Terry stressed can be converted into a fuel source.
One of the F/A-18 Navy Pilots on the Controversial Report on UFO Encounters Went on Joe Rogan’s Show

The New York Times’ UFO articles published at the end of 2017 were the perfectly appropriate amount and the best of all time for that matter. These articles document the Advanced Aerospace Threat Identification Program, which is the now-defunct UFO-monitoring project of Pentagon, and Navy pilots’ historical sightings of still-unidentified, mysterious aircraft. They did something that’s not ever done with reporting on UFOs as the U.S. government took them somewhat seriously.
The release of three videos taken by Navy F/A-18 Super Hornets made these reports more interesting. These pieces of footage each showing a blob with no visible means of propulsion maneuvering in ways impossible for the known aircraft and with a voice-over from very confused pilots.
Until today, there’s no explanation as to what these videos captured. The Navy only confirmed just last month that the videos are authentic, and the phenomena depicted/contained in them remain unidentified. According to the Navy, a patrol that was sent out to investigate a sighting earlier on the 14th of November 2004 off the coast of San Diego captured one of the three videos.
Commander David Fravor was the first F/A-18 pilot who encountered the UFO. He described seeing something vast and strange to the New York Times in 2017.
Fravor talks about his encounter for a good two hours, courtesy of Joe Rogan, and his podcast. For the most part, Fravor reiterates the story of his encounter, but there are some extra tidbits in there. In this particular interview, Fravor describes the boiling water beneath the object as if something beneath the surface about the size and shape of Boeing 737. He further suggests a theory that whatever it was underwater might have been communicating with whatever the UFO was.
Fravor also somewhat agrees or at least does not noticeably disagree with documentary filmmaker Jeremy Corbell’s categorization of the UFOs caught in the three videos possessing some non-reactionary field propulsion system.
Fravor also reveals that the craft in the Gimbal video was not alone, with radar picking up a V-formation of other, similar UFOs. According to Corbell, this particular bit of information has never been released to the public before.
Egyptian Coffin On Mars? Conspiracy Theorist Claims To Have Found Ancient Sarcophagus On NASA Mars Photo
China Built a Flying SaucerThe UFO is still on the ground—for now.
Is the Chinese government making an investment in flying saucers? It looks that way, based on images circulating from this past weekend's 5th China Helicopter Exposition, held in the northern Tianjin region. The mockup in this photo sure resembles the classic model of a UFO:
The expo, run by the regional Tianjin government, the Aviation Industry Corporation of China (AVIC), and the Chinese People's Liberation Army Ground Force, offered a chance for businesses to "demonstrate their innovations and technologies," according to its website. That's common enough for an expo, but the builders of this mockup seem to have gone the extra mile. It's assumed that a subsidiary of the state-owned AVIC built the demonstration, but it's unclear which one.
Online translations show that the ship is called a Super Great White Shark.
A rough translation from Twitter provides a description for the vehicle.
[The] Super Great White Shark armed helicopter is a composite wing-body fusion high-speed helicopter configuration designed for the future digital information battlefield. In the initial stage of its design, it refers to the international excellent and mature helicopter design technologies, such as AH-64 Apache, CH-53 Sea Stallion, and Russian Ka-52, Mi-26. While absorbing their respective advantages, it adopts the internationally popular wing-body fusion (BWB) [blended wing body] design and the former. A new type of high-speed helicopter with [a] conceptual design of propeller blades has been successfully applied in helicopter design.
The vehicle certainly looks unconventional, but the Chinese military wouldn't be the first to try out the circular design. The U.S. military has toyed with many circular vertical takeoff and landing (VTOL) vehicles, most notably the Avro Canada VZ-9 Avrocar. A joint collaboration between the Army and Air Force, each division wanted the round flyer for different reasons.
According to the Air Force Museum:
Tests with scale models at Wright-Patterson AFB, Ohio, indicated that the cushion of air under the Avrocar would become unstable just a few feet off the ground. The aircraft would be incapable of reaching supersonic speeds, but the testing went ahead to determine if a suitable aircraft could be developed for the Army. The first prototype—the Avrocar on display (serial number 58-7055)—was sent to the National Aeronautics and Space Administration (NASA) Ames Research Center at Moffett Field, Calif. There, wind tunnel tests proved that the aircraft had insufficient control for high speed flight and was aerodynamically unstable.
The second Avrocar prototype underwent flight tests that validated the wind tunnel tests. If it flew more than three feet above the ground, the Avrocar displayed uncontrollable pitch and roll motions, which the Avro engineers called "hubcapping." The Avrocar could only reach a maximum speed of 35 mph, and all attempts to end the hubcapping failed. The project was cancelled in December 1961.
It appears that Chinese builders have gone bigger than the Avrocar ever did; the test models were under 5 feet tall, but had an 18-foot wingspan. Until the vehicle is in the air, however, it's impossible to say if these engineers have solved the problems that others faced over 50 years ago.

Humans will find alien life in the next 30 YEARS says the astronomer who won a Nobel Prize this week for finding hundreds of exoplanets
A Nobel Prize winning 'planet hunter' who discovered the first planet outside of our solar system predicts humans will discover alien life in the next 30 years.
Astronomer Professor Didier Queloz, 52, from Switzerland, says he is 'convinced' that we are not alone in the universe.
The Cambridge University professor won a Nobel Prize on Tuesday for his work as a 'planet hunter', having discovered hundreds of planets orbiting suns outside of our solar system.
Speaking after the win at the Science Media Centre in London he said: 'I can't believe we are the only living entity in the universe,' The Telegraph reported.
'There are just way to many planets, way too many stars, and the chemistry is universal.
SCIENTIST WINS NOBEL PRIZE, THEN ANNOUNCES BELIEF IN ALIENSAstronomer Didier Queloz is “convinced” aliens exist — and that we could find them before 2050.
“I can’t believe we are the only living entity in the universe,” he said during an event on Tuesday — the same day he found out he’d won the Nobel Prize in Physics — according to The Telegraph. “There are just way too many planets, way too many stars, and the chemistry is universal. The chemistry that led to life has to happen elsewhere.”
The Telegraph story quotes Queloz as saying he’s certain we’ll detect signs of alien life within 100 years.
However, he also thinks it’s “realistic” to believe humanity will develop a device capable of detecting the bio-chemical signs of life on exoplanets within just 30 years.
Queloz isn’t the only notable scientist to talk aliens this week.
Former NASA scientist Gilbert Levin wrote an opinion piece for Scientific American on Thursday in which he said he also believes alien life exists — because he’s “convinced” we already detected it on Mars, back in the 1970s.
Whether Levin can persuade others to join him in that belief or not, it seems Earth’s time as the only known life-harboring body in the universe could be drawing to an end.
How the second known interstellar visitor makes ‘Oumuamua seem even odder

The second mysterious interstellar object found zipping through the solar system, 2I/Borisov, looks like a run-of-the-mill comet. That stands in stark contrast to the first known interstellar object, ‘Oumuamua (illustrated).

The second space rock seen visiting our solar system from another star is proving just how bizarre the first known interstellar object, ‘Oumuamua, really was.
‘Oumuamua raised eyebrows when it appeared in October 2017 looking more like a rocky asteroid than an icy comet (SN: 10/27/17). Because comets form farther from their host stars than asteroids, it should be easier for comets to escape their star’s gravity to wander the galaxy. So astronomers expect the vast majority of interstellar vagabonds to be icy bodies. But ‘Oumuamua didn’t sport the gaseous halo or tail that forms when sunlight vaporizes a comet’s ice.
Now, new telescope images confirm that a second interstellar object called 2I/Borisov (originally dubbed C/2019 Q4 (Borisov)) looks like a garden-variety comet, researchers report online October 14 in Nature Astronomy. The cometlike appearance of this object, first glimpsed August 30, suggests that ‘Oumuamua’s weirdness was a one-off, and that astronomers’ models of planetary systems are on the right track (SN: 9/12/19).
Astronomers observed 2I/Borisov on two nights in September with the William Herschel Telescope in the Spanish Canary Islands and the Gemini North Telescope in Hawaii. Those images reveal that, like comets native to our solar system, 2I/Borisov’s core is shrouded in a gaseous halo trailed by a faint, broad stream of gas and dust.

“It’s kind of relieving that finally we have something that meets our expectations,” says study coauthor Michał Drahus, an astronomer at Jagiellonian University in Kraków, Poland. “Now we really can be absolutely sure that ‘Oumuamua was one weird object.”
Whereas ‘Oumuamua vanished within weeks of its discovery, astronomers have several months to take a closer look at 2I/Borisov. Higher-resolution telescope images may tease out the exact size and shape of its core, and inspecting the specific wavelengths of light emanating from the comet could help astronomers flesh out its chemical composition.
Preliminary wavelength observations have already hinted that 2I/Borisov contains cyanogen gas (made of carbon and nitrogen atoms), which is relatively common in comets native to the solar system. Astronomer Alan Fitzsimmons of Queen’s University Belfast in Northern Ireland and colleagues report these findings October 2 at arXiv.org.
The second known interstellar object, a comet currently cruising through our solar system called 2I/Borisov, looks fairly different from the first discovered interstellar visitor — an asteroid-like object called ‘Oumuamua that skirted by Earth in 2017. Here are some of the key distinctions between this pair of galaxy-trotting space rocks.
| ‘Oumuamua | 2I/Borisov | |
| Constellation of origin | Lyra | Cassiopeia |
| Halo and tail | No | Yes |
| Width | 400 meters | ~2 kilometers |
| Shape | Oblong | Unknown |
| Closest distance to Earth | 0.16 au (astronomical units) | 1.9 au |
| Closest approach to Earth | October 14, 2017 | December 28, 2019 |
| Time observable | Weeks | Months |

Where Is Alien Life? Six Of The Top Theories

We have accomplished a lot in our (relatively) short time on Earth. We’ve sent humans to the Moon and to live in space, developed massive and sophisticated telescopes to see the farthest reaches of the cosmos, and even rocketed rovers to Mars and probes to the edge of our solar system. However, a number of organizations have taken humanity’s voyage into the final frontier a step farther. NASA, the European Space Agency, and the research collective behind the Search for Extraterrestrial Intelligence (SETI) have been working tirelessly to find out if we are alone, once and for all.
Already, a number of projects exist that scan the stars for signs of intelligent life. And despite the fact that many of them have been looking to the skies for decades, we have yet to make contact. And that’s a bit of a problem.
To put it mildly, our solar system is very old. In fact, scientists are still figuring out just how old — clues gathered from meteorites suggest it is almost 5 billion years old, and surrounding star systems are likely billions of years older. While interstellar travel still seems to be a distant dream, new technology is born every year that allows us to scan the skies for signals from civilizations in the most distant corners of the cosmos. The number of known alien worlds and star systems discovered through these technologies continues to rise, but our creative methods of listening to space have not yet revealed anything that resembles extraterrestrial communications or civilizations.
Given the size and age of our universe, it seems like we should have made contact. We, of course, have not.
In the early 20th century, physicist Enrico Fermi asked himself a now-famous question: Given the scope of our universe, why haven’t we found intelligent extraterrestrial life yet (or why haven’t they found us)? This is sometimes called the Fermi Paradox or the Great Silence. Scientists have floated many possible answers in the century since Fermi first asked this question. Here are some of the most plausible reasons why he haven’t made first contact.

Basic probability asserts that alien life must exist. Since we haven’t made contact yet, one theory goes, there must be something barring life from interstellar travel or, at least, barring it from communicating with other alien species. This barrier is known as the “Great Filter,” and it is a force or event that stops a civilization from getting to the aforementioned point of interstellar travel or communication.
If the theory holds true, there are two primary reasons that we haven’t made contact: Because societies kill themselves off before they reach a state advanced enough to explore the stars or interstellar travel is simply not possible on a technological scale. Neither option is particularly pleasing.
And according to the experts behind the work, the filter event is of equal or greater probability than the existence of alien life itself. This is the point argued by Robin Hanson, a research associate at the Future of Humanity Institute at Oxford University, in his discussion of the topic.
No alien civilizations have substantially colonized our solar system or systems nearby. Thus among the billion trillion stars in our past universe, none has reached the level of technology and growth that we may soon reach. This one data point implies that a Great Filter stands between ordinary dead matter and advanced exploding lasting life.
Since we have not been able to detect alien life (or leave the solar system much, for that matter), how far are we from being caught up in some event that would bar us from ever finding aliens? “The easier it was for life to evolve to our stage, the bleaker our future chances probably are,” Hanson writes. In other words, the more life there is in the cosmos, the greater the likeliness that we are about to reach a cataclysmic, life-ending event or reach the cosmic limits of technological advancement.
Another hypothesis asserts that alien civilizations certainly exist, but they’re simply inactive. That’s the “aestivation hypothesis” (aestivation refers to an organism’s state of prolonged inactivity, similar to a bear hibernating or a frog that buries itself in sand during hot weather), which was put forth by researchers from Oxford’s Future of Humanity Institute and the Astronomical Observatory of Belgrade.
The theory, published in a paper in the Journal of the British Interplanetary Society in 2017, states that aliens may be “hibernating” until the environmental conditions are just right to become active and build their super society. The researchers argue that the laws of thermodynamics directly limit computation, as computing technologies need to be cooled in order to function. This makes it exceedingly difficult to create advanced technologies, as keeping them cool at scale quickly becomes prohibitively difficult. So the aliens are falling into a dormant until, to be blunt, the universe cools.
But distilling the development of a civilization to the kinds of conditions that our current, and somewhat imperfect, models can predict could be reductive. What if intelligent extraterrestrial life has found a way around the thermodynamic conditions that limit its ability to compute? “What if there are other forms of value that can be generated?” the study authors write. If they’re wrong about the relationship between thermodynamics and technology, the aestivation hypothesis would be moot. In this case, perhaps one of the other ideas here holds true.

According to the “Gaian Bottleneck” hypothesis, life needs particular environmental conditions to develop, and they’re not so common. Astrobiologists at the Australian National University penned their explanation to the Fermi Paradox in 2016.
Extinction is “the cosmic default for most life that has ever emerged on the surfaces of wet rocky planets in the Universe,” the researchers wrote. That’s because a planet has to be actually inhabited for it to be habitable, because organisms change the concentration of greenhouse gases in the atmosphere. A Catch-22 emerges: no life without habitability, no habitability without life.
For alien life to persist, the researchers write, it must hang on: “like trying to ride a wild bull. Most life falls off.” Life can only take place with the presence of an unlikely feedback loop. In this case, Earth is the exception to the rule.
In 2015, after nearly a decade in transit, NASA’s New Horizons spacecraft became the first to do a close flyby of Pluto. It offered humanity its first look at its icy surface and raised questions about the possibility of subsurface oceans of water, and lots of methane and nitrogen. These questions put Pluto on a short but growing list of worlds with buried oceans trapped under a thick crust of ice and rock (some of the other worlds are Saturn’s moons Enceladus and Titan, as well as Jupiter’s moons Europa, Callisto, and Ganymede).
Those oceans figure prominently into another theory of where life might be lurking, one that Alan Stern, the principal investigator for New Horizons, touches on. Since buried oceans form a much more stable ecosystem than flowing surface streams, changes such as altering tides and dissipation take place over a longer time period. A hard outer shell protects hypothetical life in the oceans from a harsh climate and a lethal mix of gases on the surface. “Impacts and solar flares, and nearby supernovae, and what orbit you’re in, and whether you have a magnetosphere, and whether there’s a poisonous atmosphere — none of those things matter,” Stern told Space.com.
Any intelligent alien life that forms in these deep oceans would have to overcome a big hurdle to reach inhabitants of other worlds: drilling through that thick, protective crust. All that work would only get them to the surface — sending signals to other planets become even more unlikely.

For the past eighty years or so, we’ve been listening for signs of extraterrestrial life with radio technology. The Allen Telescope Array, situated 470 km (290 miles) northeast of San Francisco, is one of the biggest — since 2007, 42 dishes have stood at the ready to scan the skies regularly in the hope of receiving radio signals from extraterrestrial life.
But what if extraterrestrial life doesn’t operate on those frequencies? Attempts at contact could simply be passing us by simply because we don’t comprehend the right wavelengths.
Instead of using telescope arrays and scanning the skies for radio signals, Duncan Forgan at the University of St. Andrews in Scotland suggests creating a galactic communications network. The same way we blink our high beams to send a signal to other drivers, we could use the shadow that Earth creates when it passes in front of the Sun to send a message to our fellow inhabitants of the universe. Forgan suggests that we build powerful lasers that contain those encoded messages, which are sent out as we pass in front of the Sun.
“If you want to communicate with someone on the other side of the galactic centre, there’s lots of stuff in the way – dust, stars, a big black hole – so you can take the long way around using the network,” Forgan tells New Scientist. Rather than letting intergalactic messages get lost in the vastness of space, civilizations in different galaxies could agree to use this “galactic communications network” to ensure their messages get to their intended recipients – a unified system to cut through the chatter.
We’ve only been actively reaching out for alien life for about a century — a mere blip in the long history of the solar system and of the universe overall. Evan Solomonides, an astrophysics and mathematics undergrad and researcher at Cornell University, suggests that it could take a while — about 1,500 years from now, to be precise — before we hear from any extraterrestrials.
In a paper submitted to the American Astronomical Society, Solomonides examines the probability of finding life. “We predict that under 1 percent of the galaxy has been reached at all thus far, and we do not anticipate to be reached until approximately half of the stars/planets have been reached.” Solomonides believes that we will have explore around half of the Milky Way galaxy before we hear anything, which will take a while since we’ve barely explored our own galactic neighborhood.
Solomonides is careful to note that the 1,500 years is not a deadline. “This is not to say that we must be reached by then or else we are, in fact, alone. We simply claim that it is somewhat unlikely that we will not hear anything before that time.”
Humans Will Never Live on Another Planet, Nobel Laureate Says. Here's Why.
Venus May Not Have Been As Earthlike As Scientists Thought

Was Venus once covered in a liquid water ocean? A new study suggests it was not, which could diminish hope that eons ago, warm and wet conditions allowed life to arise on the planet.
Today, Venus' climate is far from temperate. The planet is completely shielded by clouds and has a hell-like surface; a runaway greenhouse gas effect makes for lead-melting temperatures of more than 700 degrees Fahrenheit (370 degrees Celsius).
But some scientists argue that the requirements for life could have existed on Venus earlier in the solar system's history. Venus is roughly the same size and mass as Earth and even had plate tectonics. The sun was also dimmer during that epoch, so Venus, despite being closer to the sun than Earth is, was in the habitable zone, or the region where a rocky planet could have liquid water on its surface.
Some scientists suggest that habitability vanished when the sun's radiation grew stronger, causing the Venusian oceans to evaporate and water molecules to be thrown into the atmosphere. Water vapor is a greenhouse gas that would have made it harder for heat to escape from the planet. The wet atmosphere began a cycle of rising temperatures, evaporating oceans and increasing water vapor that made temperatures rise even further.
In September, researchers from NASA's Goddard Institute for Space Studies released simulations of several scenarios that would allow liquid water to exist at the surface for millions of years, before this runaway effect occurred.
But the new study suggests that such water oceans were never there in the first place. While previous work hinted at a warm and wet environment based on the chemistry of the atmosphere and the higher regions of Venus, the new research suggests the highlands were made of lava rather than water.
This finding comes down to the composition of the highland rock. Previously, scientists thought the highlands were made up of granitic rock, just like continents on Earth. Granite needs a lot of water to form. But a survey of Venus' Ovda Regio highlands plateau — remapped with radar data gathered by NASA's Magellan mission, which studied Venus between 1989 and 1994 — shows the flow type is more typical of basalt rock.
"We know so little about Venus' surface," team member Allan Treiman, a Universities Space Research Association scientist at the Lunar and Planetary Institute, said in a statement. "If the Ovda Regio highlands are made of basaltic rock as is most of Venus, they were likely squeezed up to their current heights by internal forces, possibly like mountains which result from plate tectonics on Earth."
A study based on the research was published Aug. 9 in the Journal of Geophysical Research: Planets.
