... Tabetha’s star, discovered by Tabetha Boyajian a little over a year ago. A series of dips in the luminosity suggested that some irregular structure with 100 times the area of the Earth was orbiting the star. Some suggested an alien structure. Bunk (no heat signal), but still not well explained with ...
