Astronomers have discovered a batch of nine new brown dwarfs, also known as "failed stars," including the two smallest examples of these curious celestial objects ever seen. The new find could help ...

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 ...

A detailed study of a cosmic mystery known as "The Accident" has now provided new insight into the formation of clouds on ...

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 ...

"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 ...

Imagine a star powered not by nuclear fusion, but by one of the universe’s greatest mysteries—dark matter. Scientists have proposed the existence of “dark dwarfs,” strange glowing objects potentially ...

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 ...

I don’t think it’s overly poetic to say that stars are how we know the universe. When we look out at the night sky, stars are overwhelmingly what we see—thousands of them, ranging from Sirius, the ...

Celestial objects known as dark dwarfs may be hiding at the center of our galaxy and could offer key clues to uncover the nature of one of the most mysterious and fundamental phenomena in contemporary ...

"The new brown dwarfs are the least massive known brown dwarfs. They place a new constraint on the lowest mass at which brown dwarfs exist." Astronomers have discovered a batch of nine new brown ...

Zenghua Zhang, an astronomer at Nanjing University in China, and his colleagues were combing through catalogs of stars in search of cold brown dwarfs, interstellar objects that fall somewhere between ...
