Berkeley Astronomers Detect the First Known Free-Floating Black Hole

By Meher Bhatia

Berkeley astronomers, using the Hubble Space Telescope, have detected what may be the very first “free-floating” black hole ever recorded, about 2,200 to 6,200 light-years from Earth. Dubbed “stellar ghosts,” these black holes are invisible, left behind after a massive star—at least 10 times the mass of the sun—dies and collapses in on itself.
