Scientists baffled after mysterious 'alien megastructure' star starts dimming again!

Alien Megastructure Star is Acting Weird Again

Over the weekend a call went out to astronomers to point their telescopes toward star KIC 8462852, which is also known as Tabby's Star or the "Alien Megastructure" star.

One of the most favoured explanations for seemingly random light fluctuation is that a swarm of comet fragments is periodically blocking light from the star.

The conundrum involves a series of odd, erratic fading events by star KIC 8462852 - otherwise known at "Tabby's Star" after Yale University astronomer Tabetha Boyajian.

By now you have surely heard that Boyajian's star, aka Tabby's star, aka KIC8462852, is going through another weird dimming phase.

Researchers have been eagerly waiting for the brightness on Tabby's star to dip again so they can get closer readings.

Tabby's Star is in the constellation Cygnus and is approximately 1,275 light years from Earth. And now, the star is dimming down as it digests its cosmic lunch.

Researchers have thrown forth many possible explanations, including other, non-planetary celestial bodies passing in front of the star which are obscuring our line of sight, such as comets, and even the possibility that whatever is floating around the star isn't a naturally-occurring object at all, but instead a massive alien structure.

They were also asked to rate participants' attractiveness, health, sleepiness, and trustworthiness. However, researchers tell people they shouldn't worry too much about this.

"It turns out there are lots of these dips in the star's light". Some came up with the theory that the interior dynamics of the star are responsible for the dimming, while others blamed it at the group of space dust and asteroids. It has dimmed 2% so far and could continue to dim.

"We need to have a network of people around the world that are ready to jump on [and observe it]", Wright said.

That data will be crucial to pinpointing the source of Tabby's Star's unusual behavior. The largest and most powerful telescopes that will heed the call are the twin 10-meter telescopes at the W.H. Keck Observatory in Hawaii.

Researchers hope to gain time on three other big telescopes in the USA, as well as on the Green Bank radio telescope in West Virginia in their quest to unravel the mystery. The team is working to gain observing time on at least three other large telescopes on the US, according to Wright. Early this morning, astronomers detected one of those characteristic dips that are unique to Tabby's star.

However, that idea doesn't have much traction with SETI - the Search for Extraterrestrial Life Institute.

Breakthrough and the Berkeley center are now trying to get some observing time on the Green Bank radio telescope in West Virginia, according to Siemion. However, it seems that this event has happened previously three years ago, which could mean that Tabby's Star does have some sort of a pattern, according to Tabetha Boyajian whom the star was named after.
