What's 10-billion times as massive as our Sun, several times larger than our solar system, and has a gravitational influence on pretty much anything that comes within 2000 light years of its gaping, cosmic maw? Why, that would be a recently discovered black hole at the center of elliptical galaxy NGC 3842, the smaller — yes, smaller — of two supermassive black holes that astronomers have announced are the most massive they've ever discovered. The second black hole, which astronomers estimate could be as much as 37-billion times the mass of our Sun, is found at the center of a galaxy named NGC 4889. Both galaxies are a little more than 300 million light-years from Earth. "For comparison," says the study's lead author, Nicholas McConnell, "these black holes are 2,500 times as massive as the black hole at the center of the Milky Way Galaxy, whose event horizon is one fifth the orbit of Mercury"
