Astronomers have spotted a pair of brown dwarfs, which are objects in between planets and stars, which have the widest separation found to date.
It’s not uncommon for stars to be found in binary pairs, where two stars are gravitationally bound together and orbit each other. Sometimes, you even find triple star systems with three stars bound together. But typically, stars in these configurations are relatively close together. Now, though, astronomers have spotted a pair of brown dwarfs, which are objects in between planets and stars, which have the widest separation found to date.
The pair were discovered with the W. M. Keck Observatory on Maunakea, Hawaiʻi, using its Near-Infrared Echellette Spectrometer, or NIRES instrument. “Keck’s exceptional sensitivity in the infrared with this instrument was critical for our measurements,” said co-author Adam Burgasser.

Twin Brown Dwarfs Discovered, Orbiting one Another at Three Times the Distance From the Sun to Pluto - Universe TodayGravity is a funny force. The gravity of every given object technically impacts every other given object, though, in practice, large distance and small masses make those forces negligible for such interactions. But in some cases, especially when large groups are floating in empty space, gravity can still hold sway over considerable distances. Such is … Continue reading 'Twin Brown Dwarfs Discovered, Orbiting one Another at Three Times the Distance From the Sun to Pluto'
