Alien Megastructure Star Resumes Its Bizarre Behavior After 2-Year Hiatus – Futurism

In BriefOver the weekend, the so-called "alien megastructure" star orTabby's Star resumed its unusual behavior. Astronomers hope thatnew data from this recent dips in light would help explain thisbizarre phenomenon. A Series of Excited Tweets

When astronomers turn to Twitter to ask everyone who has access to a big enough telescope to look at the sky, you know something is up. Indeed, something was up this past weekend, as one of the Universes most mysterious stars reignited some baffling behavior. Tabbys Star, also known as KIC 8462852, once again started the unusual pattern of dimming its lights, a behavior first observed in 2015.

As far as I can tell, every telescope that can look at it right now is looking at it right now, Tennessee State University astronomer Matt Muterspaugh told Loren Grush at The Verge. Mutterspaugh, like fellow astronomer Jason Wright from Penn State University, noticed the dip in KIC 8462852s light emissions this past weekend.

[W]e are officially on alert and we are asking astronomers on telescopes to please take spectra (light measurements) of the star, Wright told CNet. As early as Friday, he already observed that Tabbys Star had dimmed by three percent in just a couple of days.

Discovered in 2009, KIC 8462852 came to be known as Tabbys Star because a team of astronomers, led by Tabetha Boyajian from Yale University, noticed the unusual way its light dims. Its not uncommon for a stars light to dim when planets orbiting around it pass in front of it relative to Earth. Tabbys Star, however, didnt follow the usual pattern of such dips in light, suggesting no periodic orbiting of planets or other cosmic bodies.

Naturally, such a phenomenon tugged on the curiosity of astronomers, and a number of possible explanations have been suggested. The most common, and perhaps popular among these you guessed it is that something alien is the cause. One astronomer thinks that a Dyson Sphere is causing the strange dips, thereby nicknaming Tabbys Star as the alien megastructure star.

However, as much as wed (maybe) love to find aliens at the root of this strange obvservation, other astronomers have found, and are developing, other explanations. Aliens should always be the very last hypothesis you consider, Wright told The Atlantic back then. Though, it doesnt hurt to be on the lookout.

Some think that comet swarms,debris from a devoured planet, or possibly even space dustfloating around the star are causing the unusual light emissions. Still, others suggest that it could all just be flawed data, which is why nothing conclusive has been said yet about Tabbys Star. Simply, there wasnt enough data from two years ago to say anything definitively.

We were kind of stuck in a spot where we couldnt do anything, Boyajian told The Verge. We had all the data we could, and to learn anything more, we needed to catch it in action again.

Now, there is now a lot more data to use, but it would take timefor researchers to fully consider what the information could tell us about Tabbys Star. Its also possible that the new data wont result in anything definitive, but its worth a shot. Some data is better than no data at all. At the very least, itll help us to better understand curiosities in the cosmos like KIC 8462852.
