Discovered in 1994, Gliese 229 B was the first confirmed brown dwarf, identified in orbit around a red dwarf star. Its atmosphere, rich in methane like Jupiter's, made it a unique discovery ...

Astronomers ended up publishing the discovery of the first exoplanet around a Sun-like star - 51 Pegasi b - in early October that year, and the announcement of finding the brown dwarf, Gliese 229 ...

Gliese 229 B, discovered in 1995, has long stumped scientists. Now, we know why — it is a binary system of two brown dwarfs orbiting each other, in orbit around their parent red dwarf star.

Gliese 229B is located 19 light-years away where it orbits a red dwarf called Gliese 229. In 1995, it became the first-known brown dwarf, introducing astronomers to failed stars.

Twirling pair Artist’s impression of Gliese 229Ba and Gliese 229Bb orbiting each other to create Gliese 229B. The brown dwarf pair orbit a cool M-dwarf star (shown in the distance) every 250 years.

Almost 30 years after the discovery of the first "failed star", or brown dwarf Gliese 229 B, two research groups have now independently solved its greatest mystery.

A mysterious object in our sky, Gliese 229 B, continues to intrigue astronomers. Recent revelations about its hidden identity are shaking up the world of astronomy. Astronomical discoveries often ...
