Boyajian's Star

Boyajian's Star, also known as Tabby's Star, is a star about 1,200 light-years away exhibiting unusual brightness dips—sometimes fading by over 20%—that occur irregularly. These dimming events have puzzled scientists because they don't match common explanations like planetary transits or dust clouds. Various theories have been proposed, including swarms of comets, intrinsic stellar variability, or more exotic possibilities like alien megastructures. Despite ongoing studies, the exact cause remains uncertain, making Boyajian's Star a fascinating case that challenges our understanding of stellar behavior and highlights the need for continued astronomical observation.
