"Gliese 229B was considered the poster-child brown dwarf, and now we know we were wrong all along about the nature of the object. It's not one but two." A well-studied cosmic object has stunned ...

The brown dwarf, named Gliese 229B, was discovered in 1995 but has puzzled astronomers ever since, as it appears to be too dim for its heavy mass. Now, according to two new papers in the journals ...

This artwork highlights a pair of recently uncovered brown dwarf twins, named Gliese 229Ba and Gliese 229Bb. Gliese 229B, discovered in 1995, was the first-ever confirmed brown dwarf, but until ...

Astronomers announced Wednesday that a decades-long mystery surrounding the first known brown dwarf — a “failed star” called Gliese 229B — has finally been solved. Gliese 229B confused ...

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 ...

A well-studied cosmic object has stunned astronomers. The "failed star" Gliese 229B has been revealed to be two so-called ...

To resolve Gliese 229B into two objects, the team used two different instruments, both based at the European Southern Observatory's Very Large Telescope in Chile. They used the GRAVITY instrument ...

Gliese 229B, discovered in 1995, was the first-ever confirmed brown dwarf, but until now astronomers thought they were observing a single body not two. New observations from the European Southern ...

Hundreds of papers have been written about the first known brown dwarf, Gliese 229B, since its discovery by Caltech researchers at the Institute's Palomar Observatory in 1995. But a pressing ...
