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

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

In the year 185 C.E, Chinese astronomers spotted a supernova and dubbed it the "guest star." The National Science Foundation’s (NSF) Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American ...

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 ...

WASHINGTON, Oct 18 (Reuters) - 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.

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.

"Gliese 229B was considered the poster-child brown dwarf, and now we know we were wrong all along about the nature of the object. It's not one but two." A well-studied cosmic object has stunned ...
