Strange long-term light patterns around a puzzling stellar object 1,300 light years away may actually be caused by orbiting dust, and is unlikely to be the result of an ‘alien megastructure’, scientists believe.

An unusual theory surrounding the fluctuating brightness of KIC 8462852, also known as Tabby’s Star, is that the object could be in close proximity to an alien spaceship lurking in the Cygnus constellation.

In 2011 and 2013, the light shining from the distant star dropped by 20 percent for a brief period, leading to bountiful speculation as to why. One of the theories spread online was the idea that a massive alien craft was to blame.

Well now a new study using NASA’s Spitzer and Swift telescopes has indicated that the light patterns previously observed are much more likely to be from an uneven dust cloud orbiting Tabby’s Star.

The particles, when uneven, would have the ability to dim ultraviolet light at different levels while passing over the blazing star.

“This pretty much rules out the alien megastructure theory, as that could not explain the wavelength-dependent dimming,” Huan Meng, lead author of the study at the University of Arizona, said in a statement. “We suspect, instead, there is a cloud of dust orbiting the star with a roughly 700-day orbital period.”

From October 2015 to December last year, the researchers employed ultraviolet and infrared telescopes to observe the phenomenon.

After witnessing a strong ultraviolet dip, it was surmised that the most likely cause was large particles known as circumstellar dust.

The size of the dust means it could conceivably become wrapped up in Tabby’s Star’s orbit.

According to NASA, a swarm of comets passing the star in 2011 and 2013 may also have contributed to the changing light.

The new study on the star, entitled ‘The Extinction and the Dimming of KIC 8462852’, has been published in the Astrophysical Journal.

Astronomers may have ruled out an alien megastructure as the likely cause behind KIC 8462852’s strange dimming, but it’s still mysterious — and that’s partly due to the lack of live data (as live as you can get for a star 1,277 light years away, at least). How do you understand what’s going on when you have to rely solely on historical info that doesn’t even account for the star’s spectrum? Thankfully, researchers are getting that big chance: they’ve caught the star in mid-dimming, and they have numerous telescopes trained on it. If they can record the spectrum before and after the oddball behavior, they may have a better idea of the root cause.

Scientists don’t expect to find comets. They’ve mostly ruled that out given that the dimming has taken place for several decades or more. However, the spectral data could at least point them in the right direction. If there’s consistent spectral dimming, it would point to a solid object like a planet. More uneven dimming, meanwhile, could point to dust or gas as the culprit.

A definitive answer isn’t all that likely, at least not without extended analysis. With that said, just having a general idea of what’s involved could be enough to shoot down wilder theories and narrow the focus. That, in turn, could improve humanity’s overall understanding of the cosmos and prepare for the next time researchers spot something they can’t immediately explain.
