WASHINGTON, Jan. 31 (UPI) -- U.S. scientists say they've observed a distant galaxy cluster 480 million light-years from Earth with vast clouds of hot gas that are "sloshing" about.
Astronomers at the Naval Research Laboratory studied the 30-million degree gas using X-ray data from NASA's Chandra X-ray Observatory and optical data from the Very Large Telescope, an NRL release said Tuesday.
