Simulation frames from this NASA Goddard neutron star merger animation: <a href="http://bit.ly/1jolBYY" rel="nofollow">bit.ly/1jolBYY</a> Credit: NASA's Goddard Space Flight Center This supercomputer simulation shows one of the most violent events in the universe: a pair of neutron stars colliding, merging and forming a black hole. A neutron star is the compressed core left behind when a star born with between eight and 30 times the sun's mass explodes as a supernova. Neutron stars pack about 1.5 times the mass of the sun — equivalent to about half a million Earths — into a ball just 12 mile…
