Huge Star Mysteriously Disappears for 200 Days, Astronomers Suspect Massive ‘Opaque’ Object


Scientists suggest whatever eclipsed the star was many times larger and had a hard edge.

A new study published in the Monthly Notices of the Royal Astronomical Society has shed some light on a mystery that’s puzzled astronomers for the last decade. Back in 2012, an observed star bizarrely disappeared for 200 days before reemerging – fuelling a number of theories from scientists. 

Although it’s still not entirely clear what blotted out nearly all of the star’s light, astronomers suggest it may have been eclipsed by something massive, probably with a hard edge. 

Data obtained by the scientists suggested that whatever caused the blackout was something opaque, obscuring all visible wavelengths of light.

Smith and other researchers also believe the eclipse may have been caused by a chance alignment with a dark object closer to Earth that just happened to get in the way, such as a dim dusty star. As for other explanations, an orbiting black hole surrounded by a dark, dense debris ring has also been discussed. However, astronomers have never observed something like this before.
