The James Webb Space Telescope has captured three brown dwarfs in an amazing view of star cluster IC 348, located about 1000 ...

These two brown dwarfs are gravitationally locked to each other in what is called a binary system, an arrangement commonly observed among stars. So the brown dwarf that three decades ago was named ...

Twirling pair Artist’s impression of Gliese 229Ba and Gliese 229Bb orbiting each other to create Gliese 229B. The brown dwarf pair orbit a cool M-dwarf star (shown in the distance) every 250 years.

Brown dwarfs have masses between 13 and 75 times that of Jupiter, or 0.13 to 0.75 times the that of the sun, and have cool temperatures. Thus, they emit faint, low-energy infrared light.

Gliese 229B is located 19 light-years away where it orbits a red dwarf called Gliese 229. In 1995, it became the first-known brown dwarf, introducing astronomers to failed stars.

The potential brown dwarfs are located at the edge of the SMC, a dwarf galaxy close to the Milky Way, in a young star cluster called NGC 602. NGC 602 is around 200,000 light-years from Earth.

Brown dwarfs are the heavier cousins of gas giant planets, possessing a mass between 13 to 75 times that of Jupiter. The classification is not exactly strict at both ends.

NEW YORK (AP) — A celestial object discovered decades ago is actually twins orbiting each other, a new study confirms. Scientists have puzzled over the object known as Gliese 229B, the first known ...

Using the James Webb Space Telescope (JWST), an international team of astronomers has explored the atmosphere of a nearby brown dwarf binary designated WISE J045853.90+643451.9. As a result, they ...

This illustration depicts the orbits of brown dwarf twins, Gliese 229Ba and Gliese 229Bb, with a separation only 16 times larger than the distance between Earth and the moon. (K. Miller, R. Hurt ...
