by When astronomer Tabetha Boyajian of Louisiana State University and her colleagues first saw the star known as KIC 846285, they were flummoxed.
Nicknamed Tabby's star, the object would dip in brightness at irregular intervals and for odd lengths of time, sometimes by as much as 22 percent.
Different theories were invoked, including the possibility of an alien megastructure, but nowadays, most researchers believe the star to be surrounded by an abnormal ring of dust that's causing the darkening.
