Two years ago the ESO team also found that Gliese 581’s planet “D,” which orbits its star in the “habitable zone,” could have water on the surface of the planet. “[Planet] D could even ...

The Gliese 581 star has about 30 percent the mass of our sun, and the outermost planet is closer to its star than the Earth is to the sun. The 4th planet, G, is a planet that could sustain life ...

Indeed, the most promising planet yet found—the "super Earth" Gliese 581 d, seven times Earth's mass—orbits in the habitable zone of a red dwarf star only a third the mass of the sun.

"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 ...

Hundreds of papers have been written about the first known brown dwarf, Gliese 229B ... are actually smaller in radius than Jupiter. They'd look quite strange in our night sky if we had something ...

A long-standing astronomical mystery about the first-ever discovered brown dwarf has finally been solved by scientists. The brown dwarf, named Gliese 229B, was discovered in 1995 but has puzzled ...

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 ...
