That s one big gulp: Astronomers see black hole swallow neutron star

MILWAUKEE, Wis. (AP) Talk about a heavy snack. For the first time, astronomers have witnessed a black hole swallowing a neutron star, the most dense object in the universe all in a split-second gulp. Ten days later they saw the same thing, on the other side of the universe. In both cases, a neutron star a teaspoon of which would weigh a billion tons orbits ever closer to that ultimate point of no return, a black hole, until they finally crash together and the neutron star is gone in a gobble. Astronomers witnessed the last 500 orbits before the neutron stars were swallowed, a process that took far less than a minute and briefly generated as much energy as all the visible light in the observable universe.

The blue lines are gravitational waves, ripples in time and space, which is how astronomers detected the merger, and orange and red areas indicate parts of the neutron star being stripped away.
