NASA graphic showing how brown dwarfs are more massive than planets but not quite as hugeas stars. A brown dwarf becomes a star if its core pressure gets high enough to start nuclear fusion. NASA ...

But the brown dwarf’s sweltering temperatures aren’t generated by any internal nuclear reactions of its own: Instead, it orbits very closely to its companion, a white dwarf named WD 0032-317 ...

A brown dwarf no warmer than a campfire and smaller than Jupiter is the coldest star ever found emitting radio waves. When you purchase through links on our site, we may earn an affiliate ...

An international team of astronomers has reported the discovery of a new brown dwarf, which received designation TOI-2490 b. The newfound object is about 74 times more massive than Jupiter and ...

The one Faherty's team recently discovered, named W1935, isn't near any apparent heat sources like stars, meaning it remains cold. They also found another brown dwarf that was nearly identical in ...

So the brown dwarf that three decades ago was named Gliese 229B is now recognized as Gliese 229Ba, with a mass 38 times greater than our solar system's largest planet Jupiter, and Gliese 229Bb ...

The first brown dwarf, called Gliese 229B, was discovered in 1995, but its mass was inexplicably large, says Jerry Xuan at the California Institute of Technology.

An artist's illustration shows two brown dwarf twins, named Gliese 229Ba and Gliese 229Bb. Gliese 229B, discovered in 1995, was the first-ever confirmed brown dwarf, but until now astronomers ...

This particular newly discovered brown dwarf, which is about 80 times the mass of Jupiter, is on the cusp of being massive enough to be a star. Studying it in particular can help astronomers ...

The “ultracool brown dwarf” named T8 Dwarf WISE J062309.94−045624.6 is not the coldest star ever found, but it is the coolest to be analyzed using radio astronomy, according to the team on ...

The first brown dwarf, called Gliese 229B, was discovered in 1995, but its mass was inexplicably large, says Jerry Xuan at the California Institute of Technology, who worked on one of the studies.
