Space The first brown dwarf ever found was the strangest – now we know why The first “failed star” ever discovered has been a weird outlier since it was found nearly 30 years ago.

Scientists have puzzled over the object known as Gliese 229B, the first known brown dwarf discovered 30 years ago. Brown dwarfs are sometimes called failed stars because they're lighter than stars ...
