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.

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 ...

In 1995, a parallel race was on in astronomy - one to find the first planet beyond our own solar system, and the other to find the first brown dwarf, a class of object too heavy to be a planet, but ...

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 ...

JWST has detected rare silane gas in an ancient, oxygen-poor brown dwarf, revealing a key clue to why Jupiter and Saturn hide ...

A new study has been completed in an attempt to answer some of the questions surrounding brown dwarfs. A brown dwarf is an object with a mass between that of a planet and a star. One of the questions ...

NEW YORK (AP) — A celestial object discovered decades ago is actually twins orbiting each other, a new study confirms. Scientists have puzzled over the object known as Gliese 229B, the first known ...

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 ...

Peppered throughout the universe are balls of gas that never got promoted to stardom. In a strange twist, evidence has just emerged that the most famous of these orbs is actually a double-act. Where ...

Astronomers recently spotted one of the most massive brown dwarfs known, an object between 75 and 90 times the mass of Jupiter with a beyond-scalding dayside temperature of 8,000 K (13,940° Fahrenheit ...

Brown dwarfs are astronomical objects with masses between those of planets and stars. The question of where exactly the limits of their mass lie remains a matter of debate, especially since their ...
