The first “failed star” ever discovered has been a weird outlier since it was found nearly 30 years ago. New observations show that it is unusually massive because it isn’t a single star after all ...

WASHINGTON, Oct 18 (Reuters) - In 1995, astronomers confirmed the discovery for the first time of a brown dwarf, a body too small to be a star and too big to be a planet - sort of a celestial tweener.
