Dark matter is one of nature's most confounding mysteries. It keeps particle physicists up at night and cosmologists glued to ...

In A Nutshell New theoretical models predict “dark dwarfs” — objects powered by dark matter annihilation. These cosmic bodies ...

Celestial objects known as dark dwarfs may be hiding at the center of our galaxy and could offer key clues to uncover the ...

Dark dwarfs, stars composed of dark matter, may be the optimal objects in which to finally discover physical dark matter in the real world.

Discovered in 1994, Gliese 229 B was the first confirmed brown dwarf, identified in orbit around a red dwarf star. Its atmosphere, rich in methane like Jupiter's, made it a unique discovery ...

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.

Brown dwarfs are neither a star nor a planet, but something in between. They give off their own light thanks to their sheer heat - "just like you would see embers in a fire glowing red because of ...

This illustration shows an exoplanet orbiting around two brown dwarfs –– objects bigger than gas-giant planets but too small to be proper stars. ESO/M. Kornmesser Astronomers have discovered a ...

Astronomers have now identified the tiniest brown dwarf, which is believed to be only three to four times the mass of Jupiter. The discovery was made using the James Webb Space Telescope, and it ...

Brown dwarfs aren’t massive enough to become stars, but they’re much more massive than planets. A whopping 95 new brown dwarfs were discovered as a result of this new research effort.

Astronomers have spotted brown dwarf pairs before, but these two whip around at much closer range. They orbit each other every 12 days, less than the time it takes for the moon to circle the Earth.

Gliese 229 B, discovered in 1995, is a binary system of two brown dwarfs orbiting each other, in orbit around their parent red dwarf star. Skip to content Introducing the all-new Astronomy.com Forum!
