Scientists observe huge black hole shred a star, emit x-rays

They’re known as tidal disruption events: when a black hole consumes a nearby star. And now, scientists have observed a dramatic tidal disruption event in a galaxy nearly 4 billion light years away, involving a black hole that’s approximately a million times as massive as our sun. The matter that this supermassive black hole swallowed created what’s called an accretion disk around the black hole. The supermassive black hole, called Swift J1644+57, was dormant— as 90 percent of black holes are— until it sucked in the star, shredding it. That event allowed scientists to observe the black hole. “Tidal disruption events offer us this rare view at the most common kind of supermassive black hole in the universe— these so-called dormant supermassive black holes,” Erin Kara, a Hubble postdoctoral fellow at the University of Maryland, said in a video explaining the discovery. “Tidal disruption events, where the stellar debris causes the formation of a temporary accretion disk, offers us a way to probe this population of supermassive black holes.” Read More: Fox News
