Astronomers have discovered a fascinating new object orbiting a small red star not far from Earth — a brown dwarf with powerful storms and cloudy weather patterns. The discovery, made with the help of ...

A rare quadruple star system that is the first of its kind to be discovered by astronomers could help better understand so-called "failed stars" or brown dwarfs. These celestial bodies get their ...

Two of the objects in the arrangement are cold brown dwarfs, which will serve as a benchmark for others throughout the Milky Way. By Katrina Miller Zenghua Zhang, an astronomer at Nanjing University ...

Brown dwarfs: too small to be stars, too big to be planets. Only discovered in the 1990s, these in-between cosmic objects aren't big enough to burn as hot and bright as a true star, instead usually ...

Phosphine has caused quite a stir in the astronomical world lately. That was largely due to its (still hotly debated) detection in the atmosphere of Venus. While the only known way for phosphine to be ...

"Dark matter could be captured by stars and accumulate inside them. If that happens, it might also interact with itself and annihilate, releasing energy that heats the star." "Dark dwarfs" may sound ...

An illustration of the Wolf 1130ABC triple system, which is composed of a red dwarf star (left), a white dwarf (center) and the brown dwarf where phosphine was detected (right). Adam Burgasser For the ...

Dark matter is one of nature's most confounding mysteries. It keeps particle physicists up at night and cosmologists glued to their supercomputer simulations. We know it's real because its mass ...

"The discovery provides a unique cosmic laboratory for studying these mysterious objects." A rare quadruple star system that is the first of its kind to be discovered by astronomers could help better ...
