Astronomers catch hot birth of galaxy cluster more than 11 billion light-years away
Astronomers using NASA's Chandra X-ray Observatory have observed a massive, superheated gas cloud surrounding a galaxy cluster over 11 billion light-years away. This discovery provides a rare look at the early stages of galaxy cluster formation and the role of shock heating in the universe.
