This supercomputer simulation from NASA shows one of the most violent events in the universe: Two neutron stars ripping each other apart to form black hole.
NASA says the March 29, 2014 X-flare was the best-observed in history. This post contains beautiful images of that intense event on the surface of the sun.
If astronomers had used an average desktop computer to run the new Illustris simulation, the calculations would have taken more than 2,000 years to complete.
Astronomers think hypervelocity stars happen when the galaxy's central back hole captures one of two stars in a binary system and slingshots the other out of the galaxy.
