Astronomers have observed CFBDSIR 1458 10b, a brown dwarf with a surface temperature of 97°C, making it the coolest star seen to date.
Dubbed CFBDSIR 1458 10b, the star is what's called a brown dwarf. These oddball objects are often called failed stars, because they have starlike heat and chemical properties but don't have enough mass for the crush of gravity to ignite nuclear fusion at their cores.
With surface temperatures hovering around 206 degrees F (97 degrees C), the newfound star is the coldest brown dwarf seen to date. (Related: "Dimmest Stars in Universe Spotted?")
"Over the years there has been steady but slow progress in pushing the boundaries of finding the coldest stars," said study leader Michael Liu, an astronomer at the University of Hawaii.
The previous record holder has a surface temperature of 150°C, but CFBDSIR 1458 10b may not hold its coldest star title for long as scientists are working to confirm an even cooler brown dwarf with possible surface temperatures of only 86°C.
