Searching for those two-for-one #BlackFriday deals? We’ve got one of galactic proportions for you in honor of #BlackHoleFriday. Here’s a look at two supermassive black holes spiraling toward a collision. In this supercomputer simulation, three regions of light-emitting gas glow as the black holes merge, all connected by streams of hot gas. The disks and streams of gas produce a ton of UV light and X-rays. There’s an empty circle between the two black holes that wasn’t modeled in this version of the simulation because it needed more processing power — this version took the Blue Waters supercomputer 46 days on 9,600 computing cores!
