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.

WASHINGTON (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. But it ...

Brown dwarfs are objects that straddle the dividing line between stars and planets. They form like stars, growing dense enough to collapse under their own gravity, but they never become dense and hot ...

This illustration provided by Caltech depicts the orbits of brown dwarf twins, Gliese 229Ba and Gliese 229Bb, with a separation only 16 times larger than the distance between Earth and the Moon. The ...

Using Eso’s Very Large Telescope in Chile, an international team of researchers [1] discovered a brown dwarf belonging to the 24th closest stellar system to the Sun. Brown dwarfs are intermediate ...
