A well-studied cosmic object has stunned astronomers. The "failed star" Gliese 229B has been revealed to be two so-called "brown dwarfs" that are closely orbiting each other rather than just one.

The first “failed star” ever discovered has been a weird outlier since it was found nearly 30 years ago. New observations show that it is unusually massive because it isn’t a single star after all ...

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

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

"This information will help us fill in the gaps in our knowledge of how brown dwarfs form and their relationship to stars and planets." ...

Astronomers have discovered a rocky Earth-like planet around a white dwarf star, hinting at our planet's future about eight billion years from now.

WASHINGTON >> In 1995, astronomers confirmed the discovery for the first time of a brown dwarf, a body too small to be a star and too big to be a planet — sort of a celestial tweener.

A team of astronomers has uncovered an Earth-like planet orbiting a star located 4,000 light years away from the solar system ...

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 ...

2024 — A 2020 microlensing event was caused by a planetary system with an Earth-like planet and brown dwarf. The star type was uncertain. The team has determined that the star is a white dwarf ...
