We’re Still Not Saying It’s Aliens, But ...

known as Tabby’s Star, and it set the internet ablaze a couple years back when it dimmed in ways nobody could really explain, unless you pinned it on aliens building massive structures to power their civilization.

However, since then we haven’t seen the star’s light fade, and so public interest in it did. But in April of 2017, light levels started dropping again, giving astronomers new clues to come up with new ideas. Are any more compelling than a giant energy-harvesting megastructure built by aliens? I’ll let you be the judge of that.

‘Alien Megastructure’ Star Is Dimming Again; Astronomers Sounding The Alarms

Alien Megastructure’ Star Is Dimming Again

     The most mysterious star in the Milky Way is at it again.

Astronomers are sounding the alarms Friday as telescope observations detect unusual light patterns coming from a distant star

located about 1,300 light-years away from Earth in the constellation of Cygnus, in the outer edges of the galaxy. The mysterious dimming and flickering of the star, first discovered in 2011, means something is passing in front of it. It has puzzled astronomers ever since, but this is the first time they’ve seen it dimming in real time, presenting an extraordinary opportunity to observe whatever it is that’s blocking the star’s light.

Scientists More Confused By Potential ‘Alien Superstructure’

Scientists More Confused By Potential 'Alien Superstructure'

     Within our own galaxy, some astronomers believe there may be a massive piece of alien technology, built to harvest energy from a distant star. The star, KIC 8462852, also known as Tabby’s Star, exhibits strange behavior, flickering and dimming,
By Sophie Weiner

that can’t be explained by any known astronomical phenomena. A new, unpublished study posted to arXiv, reports the results of studying images of the star from the Kepler Telescope over the past four years. The paper shows shocking results: the star’s luminosity varied, sometimes dipping by 20% over the course of the study period. Even more perplexingly, its total luminosity, or flux, diminished by 4% overall over that time.

“The part that really surprised me was just how rapid and non-linear [the dimming] was,” study author Ben Montet of Caltech told Gizmodo. “We spent a long time trying to convince ourselves this wasn’t real. We just weren’t able to.”

Alien Megastructure Mystery Will Be Settled For Good

Alien Megastructure Mystery Will Be Settled For Good

     The faraway star KIC 8462852 has been a fervent topic of debate over the last few months, ever since folks at SETI proposed that maybe—just maybe—a there was a giant alien megastructure around the star responsible for the weird readings scientists had been getting. Since then, most people have come to accept the more ordinary explanation that comets are responsible for the space oddity. But it turns out the NASA’s next great observatory, the James Webb Space Telescope, could be just the thing to answer this kind of question for sure.
By John Wenz

The hubbub all started last October when NASA’s Kepler planet-hunting telescope found a strange phenomenon around a sun-like star. Something was blocking out 20 percent of the light from KIC 8462852, since nicknamed “Tabby’s Star” after discoverer Tabetha S. Boyajian. A planet even the size of Jupiter or larger should have blocked out only 1 percent of the light. That suggests something big is here, and no Earth-based telescopes detected heat coming from whatever was blocking the light, meaning it wasn’t a planet or an asteroid.

The lead hypothesis has been, and remains, that comets are blocking out the light. A swarm of them may have collided and created a giant cloud of icy-cold debris. But even that doesn’t quite tell the whole story. For one thing, astronomers still can’t explain how there would be a cloud of comets big enough to block out that much light from a mid-sized star. It would require more mass than is found in our solar system’s entire Kuiper Belt, the region of objects that includes Pluto, an unlikely scenario.

That’s where the megastructures came in […]

Comets Can’t Explain Weird ‘Alien Megastructure’ Star

Comets Can’t Explain Weird ‘Alien Megastructure’ Star

By www.newscientist.com

      The weirdest star in the cosmos just got a lot weirder. And yes, it might be aliens.

Known as KIC 8462852, or Tabby’s star, it has been baffling astronomers for the past few months after a team of researchers noticed its light seemed to be dipping in brightness in bizarre ways. Proposed explanations ranged from a cloud of comets to orbiting “alien megastructures”.

Now an analysis of historical observations reveals the star has been gradually dimming for over a century, leaving everyone scratching their heads as to the cause.

The first signs of this space oddity came from NASA’s planet-hunting Kepler space telescope, which continually watched the star’s region of the sky between 2009 and 2013. Most planet-hosting stars show small, regular dips in light when their planets pass in front of them. But Tabby’s star dipped erratically throughout the four years, sometimes losing as much as 20 per cent of its brightness. […]

No Laser Signals Detected from ‘Alien Megastructure’ Star

No Laser Signals Detected from 'Alien Megastructure' Star

By Mike Wall

It’s looking less and less likely that a faraway star’s strange dimming was caused by some kind of “alien megastructure.”

Observations by NASA’s Kepler space telescope recently revealed that the star KIC 8462852’s brightness dipped dramatically several times over the past few years, by 22 percent on one occasion.

Such dimming events are too significant to be caused by a planet crossing the star’s face — Jupiter passing in front of the sun would dim our star by just 1 percent or so — so some astronomers have speculated that the KIC 8462852 system might harbor a giant complex of orbiting solar panels or some other structure built by an intelligent alien civilization.

In a test of this hypothesis, a team of scientists hunted for signs of potential laser communications coming from KIC 8462852, which lies about 1,500 light-years from Earth. But this search — which took place over six nights from Oct. 29 through Nov. 28, using the Boquete Optical SETI Observatory in Panama — came up empty, the researchers report in a new study.

“We found no evidence of an advanced civilization beaming intentional laser signals toward Earth,” study co-author Douglas Vakoch, president of SETI (Search for Extraterrestrial Intelligence) International in San Francisco, said in a statement.

By Mike Wall

      The mystery behind a strangely dimming star could soon be solved.

Astronomers around the world are keeping a close eye on the star KIC 8462852, which has dimmed dramatically numerous times over the past few years, dropping in brightness by up to 22 percent. These big dips have spurred speculation that the star may be surrounded by some type of alien megastructure — a hypothesis that will be put to the test if and when KIC 8462852 dims again.

“As long as one of those events occurs again, we should be able to catch it in the act, and then we’ll definitely be able to figure out what we’re seeing,” said Jason Wright, an astronomer at Pennsylvania State University. […]

SETI’s Follow up on Mysterious Star That Might Be Home To ET

SETI’s Follow up on Mysterious Star That Might Be Home To ET

The Mysterious Star KIC 8462852

By Seth Shostak

      The SETI Institute is following up on the possibility that the stellar system KIC 8462852 might be home to an advanced civilization.

This star, slightly brighter than the Sun and more than 1400 light-years away, has been the subject of scrutiny by NASA’s Kepler space telescope. It has shown some surprising behavior that’s odd even by the generous standards of cosmic phenomena. KIC 8462852 occasionally dims by as much as 20 percent, suggesting that there is some material in orbit around this star that blocks its light.

For various reasons, it’s obvious that this material is not simply a planet. A favored suggestion is that it is debris from comets that have been drawn into relatively close orbit to the star.

But another, and obviously intriguing, possibility is that this star is home to a technologically sophisticated society that has constructed a phalanx of orbiting solar panels (a so-called Dyson swarm) that block light from the star.

To investigate this idea, we have been using the Allen Telescope Array to search for non-natural radio signals from the direction of KIC 8462852. This effort is looking for both narrow-band signals (similar to traditional SETI experiments) as well as somewhat broader transmissions that might be produced, for example, by powerful spacecraft.

Serious Scientists Talking About an Alien Mega-Structure Near Strange Star

Star Map of KIC 8462852

By Sarah Kaplan
The Washington Post

     It was kind of unbelievable that it was real data,” said Yale University astronomer Tabetha Boyajian. “We were scratching our heads. For any idea that came up there was always something that would argue against it.”

She was talking to the New Scientist about KIC 8462852, a distant star with a very unusual flickering habit. Something was making the star dim drastically every few years, and she wasn’t sure what.


To Wright, it looked like the kind of star he and his colleagues had been waiting for. If none of the ordinary reasons for the star’s flux quite seemed to fit, perhaps an extraordinary one was in order.


Or, to be more specific, something built by aliens – a “swarm of megastructures,” as he told the Atlantic, likely outfitted with solar panels to collect energy from the star.

“When [Boyajian] showed me the data, I was fascinated by how crazy it looked,” Wright said. “Aliens should always be the very last hypothesis you consider, but this looked like something you would expect an alien civilization to build.” […]
