The ‘Alien Megastructure’ Star Mystery Just Got Weirder


#Alien #Megastructure – The ‘Alien Megastructure’ Star Mystery Just Got Weirder : Remember that star that caused all the fuss about alien megastructures last year? The more astronomers look at it, the weirder it seems to get. New research neither confirms nor denies that intelligent life is behind the behavior of the strangest star in the universe, but deepens in the mystery.

It turns out that the star, officially called KIC 8462852 but also known as Tabby’s Star, is behaving strangely in not just one but three different ways, according to Carnegie Science.

“This star was already completely unique because of its sporadic dimming episodes,” says Josh Simon of Carnegie Science in the news release. “But now we see that it has other features that are just as strange, both slowly dimming for almost three years and then suddenly getting fainter much more rapidly.”

Tabby’s Star is located in the Cygnus constellation, about 1,500 light years from Earth. It caused a stir when stargazers noticed that it would sometimes dim at irregular intervals, by as much as 22 percent.

It would take 22 planets the size of Jupiter to block that much light, which led to the wildly improbably speculation that an alien civilization had built some sort of superstructure that was sometimes blocking the light.

Since then, different teams of astronomers and alien-hunters have worked to confirm or deny the theory, with not much luck. Although no one has been able perfectly explain the strange light patterns through the known laws of the physical universe, efforts to prove extraterrestrials are involved have come up dry, too.

Tabby’s Star dimmed slowly, and then very quickly, between 2009 and 2013.
