ALIEN MEGASTRUCTURES ORBIT 64 NEARBY STARS SAYS ASTRONOMER

Astronomers have more or less confirmed it. Not just one, but 64 alien-like mega structures are said to be orbiting stars close to Earth. Astronomers of various credibility have claimed that these mega structures are more likely to be shaped like thin discs rather than spherically. Many astronomers have a general consensus: If you know where to look, you can probably find these orbiting alien megastructures. 

It all started out as a confusion, maybe even a glitch in the equipment that was used. However, as checks were done, more and more confirmed that this was not a technical error. Tabetha Boyajian, a postdoc at Yale, told The Atlantic that "It was really weird. We thought it might be bad data or movement on the spacecraft, but everything checked out.” This means to say that this is not a false alarm, but a rather shocking and true statement of fact from a credible source.

Many astronomers, based on the research that they have gotten, are now starting to gather evidence that these mega structures are actually the Dyson Sphere - a theory that was hypothesized by the physicist and mathematician Freeman Dyson. The Dyson Sphere isn't some fairy-tale - it proves that super advanced civilizations are out there in the galaxy. We are not alone.

Why does this prove that super advanced civilizations, so much more advanced than humankind actually exists? In his theory, Dr. Dyson theorized that as a civilization advances, its energy demand constantly increases, and exponentially, one day, if human civilization were to last long enough, this energy output could actually rival that of a sun.

The Dyson Sphere is a theory of a mega machine that is able to collect the power output of an entire star. Who needs that much energy to power their homeland, and what do they have that requires that much power? Do these logical questions sound scary enough to you yet? 

An illustration of the megastructures stealing energy from a star

The theory that humankind is not alone in the entire universe might seem like a far-fetched tale, but in recent years, and as our technological advances in research and Space improves, humankind finds more and more shocking secrets - let us hope that these alien like mega structures are one from a friend - not a foe, if not we would have a reenactment of the Marvel movies - but in real life. If that doesn't sound scary enough for you, nothing ever will.

ENGINEER TALKS ABOUT HIS WORK WITH UFOS AND ALIENS AT AREA 51

Bill Uhouse, a former mechanical engineer, revealed that he used to work in collaboration with Grey Aliens at Area 51. One alien he named "J-Rod" taught him how to use the alien vehicle.

The interviewer was German ufologist and author Michael Hesemann. I can hear it from his voice cause he has a little speech impediment. He wrote many good books about UFOs too.

Australian government reviews funding for UFO group

If Australian UFO enthusiasts hope to retain government money, they may need more proof of terrestrial activity.

The nation's Social Services Minister, Christian Porter, has described having "a beam me up, Scotty" moment after learning his department had approved grants to the Tuggerah Lakes UFO Group.

The group has received A$6,000 (£3,400; $4,500) since 2013 under funding to support volunteers with disabilities.

Mr Porter has halted the payments to seek "more detail" about the group.

"I'm sure they are very nice people and there are lots of volunteers who are getting something out of it, but looking at it from my perspective, representing taxpayers, it did not seem to pass a common sense test," Mr Porter said on the Australian Broadcasting Corp.

Funds on hold

The New South Wales group has more than 800 members on Facebook, where it says it shares "news, information, support friends and network in UFO matters as well as related topics".

When asked about apparent sightings in the region, Mr Porter said: "You tend to find a lot of sightings when you are funding UFO-sighting groups, I tend to think. But we will see what they are about."

The Tuggerah Lakes UFO Group has been contacted for comment.

A person identified as a spokeswoman told the Central Coast Gosford Express Advocate: "We have elderly people we pick up and take to meetings, where we need projectors and microphones so everyone can see and hear what is going on."

Australian government investigating taxpayer funding of UFO group

Australia's social services minister on Friday launched an urgent investigation to determine how a UFO group received thousands of dollars in taxpayers' funds.

Christian Porter described having a "beam me up, Scotty" moment when he discovered that his department approved nearly AUD6,000 (£3,400) of grants for the Tuggerah Lakes UFO Group on the New South Wales central coast since 2013.

"I'm sure they're very nice people and there are lots of volunteers who are getting something out of it, but looking at it from my perspective, representing taxpayers, it didn't seem to pass a common sense test," Mr Porter told ABC News.

"I asked the department to hold the transmission of funds until they could give me a little more detail around what the group does."

The funding, exposed by national news, was initially provided by the Labor government to assist with the cost of transporting volunteers with a disability.

Asked about the Central Coast's reputation as a UFO sightings hot spot, boasting the most apparent sightings of UFOs in the country, the minister said that "you tend to find a lot of sightings when you're funding UFO sighting groups."

The department approved AUD2,645 for the UFO group in the 2017 volunteer grant program, according to official records seen by ABC News.

Mr Porter said that the money transfer has been currently put on hold until he is given more detail about what the group does specifically.

Tuggerah Lakes UFO Group received AUD2,994 in 2013 under Labour government.

The Tuggerah Lakes UFO Group has over a thousand followers on Facebook where it says that its mission is to "share information on UFO and related topics, support and encourage likeminded people and encourage UFO Disclosure."

The Telegraph has contacted the UFO group for comment.

AMAZING! British Bus Driver In Exmouth Videotapes Triangular UFO

Three lights in triangular formation were reportedly spotted and recorded on video slowly crossing across the sky above Exmouth in East Devon, England. The British witness, who is a bus driver, noticed the strange lights at 9:41 p.m. on April 17, 2017, while on a break.

The unnamed witness was talking on the phone to his best man for the upcoming wedding while walking near the leisure center where their bus stopped. When he happened to look over in the river, the witness then saw the three lights forming a triangular formation while rotating on its axis and wobbling slightly.

He then felt that the triangular object was unusual. The witness told his mate that he would call back and started recording the lights using his phone. However, the witness was having a difficult time focusing on the formation due to the street lights. To get a better view, the witness decided to go closer to the river.

The witness managed to record almost a 3-minute video initially. He also took seven pictures and another 41-second video. He filed a report to MUFON along with the video of the incident and some pictures. MUFON filed the report as Case 832412 and can be accessed in their witness reporting database. The case is still under investigation led by British MUFON field investigator Karl Webb.

Canada Denies Shag Harbour UFO 50th Anniversary Funding

 MJ Banias

This year will mark the 50th anniversary of one of the best documented UFO incidents in history, and the community of Shag Harbour applied for a government grant to fund a large celebration. Alas, the Canadian government axed their request which has left organisers scrambling.

At around 11:20 pm on October 4th, 1967, the small fishing village of Shag Harbour in Nova Scotia, Canada was awakened to a loud whistling noise followed by the sound of a crash. A dozen of witnesses saw a bright illuminated object crash into the harbour, and watched for nearly 30 minutes as a bright round shape floated upon the water’s surface before it sank under the depths and vanished. Contacting the Royal Canadian Mounted Police (RCMP), the local detachment sent several officers to the location. Fearing an aeroplane crash, they contacted the Coastguard and the Navy. Local fishing boats went out into the bay to look for survivors, but nothing was ever found and no aircraft were reported missing.

The Shag Harbour UFO Incident is one of the best documented UFO incidents in history. Investigations were conducted by the RCMP, the Canadian Navy and Air force, as well as the US led Condon Committee. A media frenzy followed the event, and the Navy even spent several days after the event combing the sea floor looking for the object. Whatever the people of Shag Harbour saw that night, it has never been identified.

Canada is turning 150 years old this year, and to generate excitement, the Canadian government created a grant program called “Canada 150” to help fund major celebrations around the nation. The Shag Harbour Incident is celebrating its 50th anniversary, and the community wanted to do something special.

The society’s vice-president, Brock Zinck, said in an interview,

We can’t get a lot of love here in Shag Harbour; they won’t even give us a [highway] sign…Maybe the government doesn’t want to know we are there.

In regards to the loss of the grant money,

We were excited…It does throw a wrench in our preparations. We had big plans to take it to the next level.

The Shag Harbour Incident Society applied for $20,000 to put on a major event, including a conference with UFO experts and speakers. Many of these speakers had to be flown in from across Canada and the from the United States. The event would have brought significant tourism to the quiet village of 500 people, and the economic benefits would have been significant.

UFO researcher and science writer Chris Rutkowski was slated as one of this year’s guests. Author of several books on UFOs, his latest release, “When They Appeared” came out only two weeks ago. In an exclusive interview with Mysterious Universe, in regards to the benefits of such an event, he stated,

It would have been quite appropriate for a Canada 150 event because it is one of the best-known Canadian [UFO] cases, and one that attracts visitors to Nova Scotia. It certainly would be at least as important as a local community event involving mainstream or more traditional historical projects like museums and artwork.

The internet and its host of conspiracy theorists has taken this denial of funding as another aspect of the “truth embargo” regarding the UFO phenomenon. Perhaps the government is hiding something, and the less attention the Shag Harbour event gets, the better. Most people believe that other cultural events simply took precedence, and the Canada 150 grant committee simply had to make cuts to certain requests.

However, the UFO community in Canada has not taken this news sitting down. Podcasters and UFO enthusiasts around the nation are continuing to bring awareness to the event. Tickets are still for sale, and the society plans to host the event anyway, just on a more grassroots level. Event planners are hoping for the best, and praying for a miracle. The event is slated for September 29th to October 1st 2017, with a celebration party on October 4th.

TR-3B Flying Triangle UFO Patent Now Available to the Public

 Paul Seaburn

If you’re one of the hundreds, if not thousands, of people who have seen a triangular UFO over the past two decades or so, now you can see what its original design diagrams look like, courtesy of a viewer (Darian Calhoun) of the Talk is Cheap video podcast and Corey Goode, an unusual fellow who tweeted a link to the podcast and his followers took care of spreading it on the Internet. Where did the diagrams come from? The original patent US 20060145019 A1 for a triangular spacecraft that became the TR-3B!

A spacecraft having a triangular hull with vertical electrostatic line charges on each corner that produce a horizontal electric field parallel to the sides of the hull. This field, interacting with a plane wave emitted by antennas on the side of the hull, generates a force per volume combining both lift and propulsion.

Does that sound like what you saw? The patent, filed on December 20, 2004, by inventor John St. Clair, gets mathematical fairly quickly, but the drawings and abstract make it clear that this is an entirely new spacecraft with a futuristic propulsion system.

This invention relates to a spacecraft propulsion system utilizing a rotating octagon of trapezoidal electrically charged flat panels to create an electric dipole moment that generates lift on the hull. On the interior side of each panel are electrostatically charged rods which produce a planar electric field that emerges from holes in the panel to form an ellipsoidal potential energy bubble on the outside of the hull. The rotating hull dipole moment generates a magnetic moment which, together with the magnetic field gradient developed by the rotating electric field of the electrostatically charged panels, produces said lift force. The potential energy field is enhanced by using a double cladding of hull material with different ranges of permittivities.

Throw in some comments like “This combination of fields produces a spacetime curvature as determined by Einstein’s General Theory of Relativity” and it’s no wonder the military keeps it so well hidden … except for this patent that’s been hiding in plain sight. It’s not clear how “Darian Calhoun” stumbled upon it, but kudos to Talk is Cheap for bringing it out into the open where Corey Goode picked it up.

For those not familiar with him, his Sphere Being Alliance biography describes Corey Goode as “an intuitive empath” (IE) who was recruited at age 6 for a MILAB program (indoctrination for black ops program) where he eventually supported a “rotating Earth Delegate Seat (shared by secret earth government groups) in a “human-type” ET SuperFederation Council.”

He claims to have worked in a “Secret Space Program” interfacing with “non-terrestrial beings.” Goode now works in the information technology and communications industry as well as continuing to use his IE ability to communicate with the Blue Avians (of the Sphere Being Alliance) and “interface with multiple ET Federations and Councils” to “deliver important messages to humanity.”

Like the TR-3B patent? There’s obviously more to this. Iit seems strange that the patent just “suddenly” was discovered. Will someone from the military or the government issue any comments, confirmations or disclaimers? They haven’t so far. For now, we’ll just have to wait for more from Corey Goode.

Social Services Minister Christian Porter, whose department dishes out the volunteer grants, is in disbelief.

"It was a bit of a 'beam me up Scotty' moment when I found out about it," he told ABC TV on Friday.

"I'm sure they're very nice people and there are lots of volunteers who are getting something out of it but looking at it from my perspective - representing taxpayers - it didn't seem to me to pass a commonsense test."

Mr Porter has requested his department hold any funds until he gets more information about exactly what the group does.

The group, which has more than 800 members on Facebook, is said to share news and information of UFO matters and support friends and networks.

NSW's Central Coast has long been a hotspot for UFO sightings in Australia.

"It's very hard to unpack cause and effect; you tend to find a lot of sightings when you're funding UFO sighting groups.

"But we'll see what they're all about."

The minister's office has been advised the group was previously funded under the Labor government in 2013 and that some of this grant goes to the transport costs of volunteers with a disability.

(EFKS)

As we perhaps draw thrillingly/terrifyingly closer to discovering life elsewhere in the universe, the chorus of people warning us to be careful what we wish for is growing louder. Most famously, renowned physicist Stephen Hawking has argued for hitting the brakes, reiterating as recently as 2016 his concern about seeking alien contact in his comments about possibly life on Gliese 832c: "One day, we might receive a signal from a planet like this. But we should be wary of answering back. Meeting an advanced civilization could be like Native Americans encountering Columbus. That didn't turn out so well." For example, European germs were deadly for the natives and some fear that could happen to us.

Astrobiologist Lewis Dartnell, however, disagrees with all of this. From his perspective, things are considerably less scary than many think. In an article recently published on Literary Hub, he offers a host of comfortingly solid arguments for why we should stop worrying.

1. Why Aliens Wouldn’t Want to Enslave Us or Breed with Us

Sure, humans have repeatedly enslaved other humans throughout our history, but we’re not that advanced. Our collective sense of guilt may be making us fear that someone else will do to us what we’ve done to others. Dartnell says we’re looking at this wrong.

There’s an increasing concern that we’ll soon find ourselves competing for jobs with robots. After all, they may offer a more efficient form of labor than us humans. Dartnell points out that any civilization advanced enough to traverse space and arrive here would have no need for slaves. He writes, “Constructing robots, or other forms of automation or mechanization, would be a far more effective solution for labor—people are feeble in comparison, harder to fix, and need to be fed.”

(ROMMEL CANLAS)

As far as wanting us for breeding purposes, Dartnell’s points out how perfectly in sync two organisms’ chemistry has to be to allow mating — in fact, such mismatches are what separates one terrestrial species from another. For reproduction to be possible, here’s a short list of some of the things aliens would have to share with us. The same:

• polymer, or RNA, we use for storing genetic information

• A, C, G, and T genetic letters we use

• coding system that that translates the letters into proteins

• chromosomal organizational structure

Given how rare a workable match is even here on earth, Dartnell concludes it’s “overwhelmingly improbable that an alien life form from a completely different evolutionary lineage would be compatible.”

2. Why Aliens Wouldn’t Want to Eat Us

As food, it’s likely we wouldn’t agree with them. In order for an alien to derive any nutrition from us, they’d have to be biochemically similar. They’d have to have enzymes that allow them to successfully break down and make use of the polymers of amino acids, polymers of bases and sugars, and membranes of phospholipids from which we’re made.

Dartnell points that while there’s a chance they’d be made of the same stuff as us — amino acids, sugars and fatty molecules have all been found in meteorites , suggesting they’re common across the universe — there’s an interesting additional wrinkle: Enantiomers. Simple organic molecules can occur in mirror images of each other. As Dartnell says, it’s like how your two hands are the same, but can’t be placed atop each other in alignment. All life on our planet has “left-handed” amino acids and “right-handed” sugars, and any creatures looking to us for sustenance would need to have the same, even if they do share our basic microbiology.

Unless we’re just really tasty.

3. Why Aliens Wouldn’t Come Here to Steal Our Water

Europa (NASA/JPL/DLR)

Simply put, there’s plenty of water everywhere, water that would be easier to acquire than the stuff we have. A thirsty alien visiting our solar system would probably head straight for Jupiter’s moon Europa, which holds more liquid water beneath its frozen surface than we have here. There also appears to be lots of water on other icy moons and even in comets and asteroids, the likely sources of our own H2O. It would be easier to suck it off one of those smaller bodies than from a planet like ours with so much gravity trying to hold our water in place.

4. Why Aliens Wouldn’t Come Here for Some Other Raw Material

(DC COMICS)

Again, asteroids seem like a more logical place to get any of the building materials we have here such as iron, nickel, platinum, tungsten and gold. The lack of gravity would again make them easier to extract from a smaller body. In fact, there are companies on earth planning asteroid mining operations.

What Dartnell suggests may make us a bit more special in this regard is plate tectonics, which hasn’t been seen many other places so far, and could theoretically produce something we’re unaware of that an alien might want. Maybe.

5. Why Aliens Wouldn’t Want to Colonize and Live Here

(REUT C)

As an astrobiologist, Dartnell admits that earth hosts a variety of conditions that make it especially suitable for supporting complex life, and that it could therefore be attractive to an extraterrestrial species looking for a new home.

However, he points out that any civilization capable of traversing the mind-boggling expanses of space is probably more than capable of artificially managing, or “bioengineering,” the environment of any planet to make it habitable. If this is so, why would aliens bother with having to eradicate the billions of organisms here that are unlikely to line up with an alien’s own unique biochemistry? It would be quicker and easier to simply design and build a compatible biosphere somewhere free of bothersome inhabitants.

So Why Would Aliens Come Here at All?

From Close Encounters of the Third Kind

Dartnell suggests that if aliens do appear, it may simply be that they want to meet us. “I suspect that if aliens did come to Earth, it would be as researchers: biologists, anthropologists, linguists, keen to understand the peculiar workings of life on Earth, to meet humanity and learn of our art, music, culture, languages, philosophies and religions” he writes.

And Where Are They, Anyway?

Dartnell asserts that since we’ve been sending signals out into the void for nearly a century — and recently, intentionally doing so — yet no one has responded, one of two things are most likely:

1. Either no one’s out there, and we’re alone.
2. There’s so much intelligent life in the universe that we’re not that special.

Either possibility packs an emotional wallop.

For many of us, the thought of aliens visitation began with movies like Close Encounters of the Third Kind that had us scanning the night skies with a hopeful sense of expectation. Lately, however, some have been shifting our gazes downward with a fearful sort of, “nope, nothing here to look at, keep flying by” attitude. Darnell’s argument makes so much sense, though, that it feels safe once again to look back upward in excitement at that sky full of promising stars.

 Atmosphere that could support alien life found on Earth-sized planet

Harley Tamplin for Metro.co.uk

Scientists are getting excited at the prospect of finding alien life on a recently discovered Earth-sized planet.

The planet, LHS 1140b, is one of seven orbiting a star named Trappist-1.

Soon you'll be able to watch Netflix across Europe as EU bans geographical restrictions

It has immediately been pushed to the front of the queue in the quest to find alien life – because it lies in the ‘Goldilocks’ zone.

This is an area from a star where the surface temperature is not too hot, or too cold, but just right.

This means water could flow in liquid form, rather than as ice or vapour, allowing life to flourish.

Astronomers studying the rocky world believe its atmosphere could have supported the world for billions of years.

Jason Dittmann of the Harvard Smithsonian Center for Astrophysics said: ‘This is the most exciting exoplanet I’ve seen in decades.

‘We could hardly hope for a better target to perform one of the biggest quests in science – searching for evidence of life beyond Earth.’

Further studies are set to take place on the planet, which is 39 light years from Earth.

All seven of Trappist-1’s planets are considered potential candidates for having water in some form, but the chances are highest for three located in the Goldilocks zone.

Xavier Bonfils, an astronomer at the Observatory of the Sciences of the Universe in Grenoble, France, said LHS 1140b now ‘joins Trappist-1 at the head of the rankings’.

He said: ‘We are very excited by this discovery. It’s a super opportunity.’

Ian Sample Science editor

An Earth-sized world that swings around a star in the constellation of Aquarius has become a priority in the search for extraterrestrial life after scientists found that an atmosphere could have enveloped the planet for billions of years.

The planet is one of seven circling a small and feeble star called Trappist-1 which astronomers reported in a wave of excitement in February this year. The rocky world lies in the habitable zone around its parent star, where temperatures should allow for free-running water, but that would count for little if the planet has no atmosphere.

“Since the discovery of the seven planets there has been a great deal of interest in using telescopes such as the upcoming James Webb Space Telescope to determine whether these planets have atmospheres, and if so, what their composition is like,” said Manasvi Lingam at Harvard University. “It is fair to say that the presence of an atmosphere is perceived as one of the requirements for the habitability of a planet.”

If Earth serves as a good example, the evolution of complex and ultimately intelligent life calls for an atmosphere that not only contains the right blend of gases, but which persists for hundreds of millions, or preferably billions, of years.

With Nasa’s James Webb Space Telescope not due to launch until late 2018, the scientists turned to computer models to find out whether the Trappist-1 planets could have long-lived atmospheres. From details of the Trappist-1 system, which lies 39 light years distant, they worked out the intensity of the stellar wind – the rush of high energy particles streaming out of the star – and the effect it would have on the seven orbiting planets.

Atmospheres that exist around planets soon after they form can gradually be stripped away if they are battered by a strong stellar wind from their parent star. The model showed that the stellar wind from Trappist-1 was much faster and far more dense than the solar wind that reaches Earth. On Trappist-1b, the first planet from the star, the stellar wind was 1,000 to 10,000 times stronger than the solar wind that strikes Earth.

The intensity of the solar wind destroyed the atmospheres of the inner Trappist-1 planets within millions of years. But planets further out fared better, their atmospheres surviving for billions of years, the models found. According to the scientists, while the seventh planet around the star is considered too cold for liquid water to exist on the surface, the sixth planet, Trappist-1g, appears to be the most likely home for life in the Trappist-1 system.

In a report submitted to a leading journal, the scientists write: “The outer planets of the Trappist-1 system, which are expected to retain their atmospheres for longer periods, may therefore support more complex biospheres eventually.”

Amaury Triaud, an exoplanet researcher at Cambridge University who helped discover the Trappist-1 planets said: “The work is quite optimistic that the planets could retain an atmosphere, which is nice to hear. It prepares us for what we might or might not see. Maybe we’ll find atmospheres that are denser and denser for the outer planets.”

“Having too much of an atmosphere containing a lot of hydrogen would be detrimental for life, but if you strip everything down to the surface, it’s also no longer habitable. The moon is the same distance from the sun as the Earth and it has absolutely no signs of life,” he added.

Astronomers have now detected about 3,600 planets beyond the solar system. The Trappist-1 planets orbit incredibly close to their parent, an ultracool dwarf star the size of Jupiter that shines 2,000 times less brightly than the sun. Mercury, the innermost planet in our solar system, is six times farther from the sun than the outermost seventh planet is from Trappist-1.

All seven of the planets have Earth-like dimensions, ranging from 25% smaller to 10% larger than our home planet. Most, if not all, will be “tidally locked”, meaning they show only one face to their star. Such worlds would be defined by stark divisions, with one half in constant daylight, and the other in permanent darkness.

“We don’t really know how life started,” Triaud said. “Some people say life was born at the bottom of the ocean. If that is the case and there is a lot of water on the Trappist-1 planets, then it’s good news: it doesn’t matter which side it is on, because at the bottom of the ocean you have no light at all.

“But if life is born on the surface then the UV irradiation the planets receive is important. It drives chemical reactions to begin with, but it can become an issue for DNA mutations, and whether they were on the day or the night side would matter. There really are a lot of elements,” he said.

UFO hunters spot ‘flying disc’ near International Space Station

UFO hunters spot 'alien tank' on the Moon

A mysterious object appeared to have hovered past the International Space Station, according to new video footage from UFO researchers.

SecureTeam 10, who in recent days has posted videos about a supposed alien tank and a cigar-shaped disc over Paris, claims that a disc-shaped object whizzed past the ISS “at a very high rate of speed.”

NASA, which did not respond specifically to the latest video, has often said the objects are “distortions in a lens” and do not signify the presence of extraterrestrial life.

Tyler Glockner, the voice heard on the video from SecureTeam 10, said the object in the video moved “as if it knew the camera was watching.”

Ever since astronomers announced the discovery of an Earth-sized exoplanet less than five light years down the cosmic street, the question on every good space cadet’s mind has been whether or not we can colonize it. We’re not going to know if Proxima b is habitable until we can point some very powerful telescopes at it, which won’t happen until next year. But until then, scientists are playing around with models—and one such modeling effort recently came to some promising conclusions.

If Proxima b has an Earth-like atmosphere, researchers found, it might just be a comfortable place to live. A (probably) rocky planet located a measly 25 trillion miles away, Proxima b lies squarely in the “habitable zone” of its star—a tempestuous red dwarf called Proxima Centauri—meaning it might be able to support liquid water, and even life. The latter is still a big question mark, but as we wait for more data, a UK-based team of scientists is trying to figure out whether Proxima b might have the stable climate and reasonable temperatures necessary for life.

So the researchers turned to the Met Office Unified Model, one of the foremost models for studying the climate here on Earth. The team modified this model for extraterrestrial forecasting by considering two potential atmospheres: an Earth-like one rich in nitrogen and oxygen, and a simple nitrogen atmosphere containing trace amounts of CO2. Then they ran their simulations considering a few hypothetical orbits for Proxima b, including one in which the planet is tidally locked, with a permanent dayside and a permanent nightside, and an orbit similar to that of Mercury. The researchers also considered differences in the star’s light output, which produces more infrared and less visible light than our Sun.

Overall, the findings published this week in Astronomy and Astrophysics were promising. In both tidally locked and Mercury-like orbits, the planet’s hypothetical climate featured stable surface temperatures conducive to liquid water, supporting and extending the results of previous studies. Although not all parts of Proxima b were habitable in all simulations (the night side in the tidally locked scenario hovered around a nice, balmy -200 degrees Fahrenheit), the models pointed to enough warmish regions to make our neighboring exoplanet a very acceptable interstellar vacation spot.

Caveats abound, however. First and foremost, these models assume Proxima bhas an atmosphere, which might not be the case at all. In fact, as another recent modeling study demonstrated, planets in tight orbits around red dwarf stars might be getting lashed by an insane number of high-energy solar flares, stripping their atmospheres faster than they can be replenished. No atmosphere, no rivers, lakes or oceans, no life as we know it.

The model has other limitations, too—for instance, it didn’t consider what the surface of Proxima b is like at all. As we know from studying Earth’s climate, the mixture of land, water, and ice coating a planet has an enormous impact on its temperature.

Avi Loeb, chair of Harvard’s astronomy department and an advisor for Breakthrough Starshot, an effort to send an interstellar probe to the Alpha Centauri system (which includes Proxima Centauri), called the study’s results “encouraging” but agreed that the results are “predicated on an atmosphere being present which remains to be seen.” The way forward, Loeb told Gizmodo, is to figure out whether Proxima b actually has an atmosphere by observing it, and if so, to figure out what it’s made of.

Both questions require more powerful telescopes than our current state of the art, but the technology is on its way. In the meantime, studies like this inject hope in the quest to find habitable worlds beyond Earth, serving to inspire scientists and motivate further investigations. Maybe we’ll even make that interstellar voyage to settle the matter once and for all.
