Record-breaking Black Hole

  A black hole that trumps all others in size was detected by two NASA satellites and announced by researchers, led by Andrea Prestwich at the Harvard-Smithsonian Center for Astrophysics. The black hole is a hefty 24 to 33 times larger than the Sun (the previous best was 16 times larger).Sitting 1....

The finding expands researchers’ understanding of just how massive a black hole can be. "We now know that black holes that form from dying stars can be much larger than we had realized," Prestwich says.
