A supermassive black hole with an exceptional 7-minute flash may have a “stellar companion.” Of three possible explanations, one is a white dwarf star caught in the black hole’s gravity.

Astronomers have discovered a "teenage vampire" dead star in the process of devouring a companion star during a short-lived, "missing link" phase of its evolution.

A black hole infamous for strange features has once again baffled astronomers, this time with rapid X-ray flashes. What could they be?
