Something Big Came OUT Of A Black Hole Recently! Scientists Baffled 3/15/16
You don’t have to know a whole lot about science to know that black holes normally suck things in, not spew things out. But NASA detected something mighty bizarre at the supermassive black hole Markar...
A Tour of SDSS J1354+1327 - For The First Time, Astronomers Caught a Black Hole Spewing Out Matter
Astronomers have caught a supermassive black hole in a distant galaxy snacking on gas and then burping — not once, but twice. The dining galaxy is known by its abbreviated name, J1354, and is about 8...
