Mysterious star ends its strange dimming eventThere's still no solid explanation on why "Tabby's Star" varied in brightness over the past few days. It could have been a planet or some kind of alien structure for all we know.
A Star was dimming, but why? On May 19th, a star known as KIC 8462852 started dipping in brightness. The star is also known as Tabby's Star, named after astronomer Tabetha Boyajian. Tabby's Star is around 1,300 lightyears away from Earth. It was first discovered in 2011. Data collected by the Kepler space telescope revealed that Tabby's Star emitted light patterns unlike any of the 150,000 stars Kepler have recorded. When dimming of stars is observed, it means something is passing in front of it. Hardly, the dips and brightness of Tabby's Star did not follow any obvious patterns. if a planet is responsible for dimming, it usually occurs in regular intervals. Also, the light dimmed from 3% to more than 20%. So, what's causing this dimming? Here are the possibilities. Boyajian thinks it could be a duplicate of an event that happened several years ago, observed by the Kepler space telescope. That would suggest it is the same object passing in front of the star. Some people like astronomer Jason Wright postulates the dimming could be caused by huge megastructures that are orbiting the star. So maybe aliens caused this. Right now there are no firm findings on what What exactly passes in front of Tabby's Star? By Monday, May 22nd, the dip seemed to be over, and Tabby's Star was returning to its normal brightness.
