These 'failed stars' orbit so closely it took 29 years to tell they were a pair

"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 o

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 revelation means that Gliese 229B is a "first-of-its-kind" tight brown dwarf binary, increasing the hope other such exotic systems dwell in the Milky Way just waiting to be discovered. The finding also solves a long-standing mystery about Gliese 229B, explaining why this brown dwarf appears too dim for its mass.  "Gliese 229B was considered the poster-child brown dwarf," team member and California Institute of Technology (Caltech) researcher Jerry W. Xuan said in a statement. "And now we know we were wrong all along about the nature of the object. It's not one but two. We just weren't able to probe separations this close until now."

Using the James Webb Space Telescope, University of Copenhagen researchers have become the first to see the formation of three of the earliest galaxies in the universe, more than 13 billion years ago. The sensational discovery contributes important knowledge about the universe and is now published in Science. For the first time in the history of astronomy, researchers at the Niels Bohr Institute have witnessed the birth of three of the universe's absolute earliest galaxies, somewhere between 13.3 and 13.4 billion years ago.
