A mysterious object in our sky, Gliese 229 B, continues to intrigue astronomers. Recent revelations about its hidden identity ...

One brown dwarf with around 38 times the mass of the solar system gas giant and another with around 34 Jupiter masses. Gliese 229 B's dual nature raises the question of how such tightly bound ...

Astronomers believe they've spotted the tiniest stars: brown dwarfs only a few times the size of Jupiter, lurking dimly in the darkest depths of space. Yes, Jupiter is a standard unit of mass! "For ...

Within GRAVITY’s combined observations, Xuan’s team discovered that Gliese 229 B was not a single object, but a pair of brown ...

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 ...

An international team of astronomers has figured out that a famous brown dwarf is actually a pair of tight-knit brown dwarfs, weighing about 38 and 34 times the mass of Jupiter, that whip around ...

"This is the most exciting and fascinating discovery in substellar astrophysics in decades," an astrophysicist said.

Gliese 229B was the first known brown dwarf, discovered in 1995. These objects are much larger than gas giant planets. Gliese 229B was estimated to be about 70 times more massive than Jupiter.

The James Webb Space Telescope has discovered the first brown dwarf star candidates outside the Milky Way. The European Space Agency (ESA) said that these candidates reside in the star cluster NGC 602 ...
