These short GRBs are immense bursts that emit the same amount of energy as all of the stars in our entire galaxy combined produce in a year, in only around 2 seconds. These events are particularly interesting because scientists believe that they may result in short gamma-ray bursts (GRBs). Watch the mesmerizing simulation unfold in full below: As the stars merge, the overwhelming mass acquired by the larger star causes it to collapse, and a black hole is born. As the stars start to whirl toward each other, immense tidal forces warp the crusts of the stars and the smaller star explodes, spewing its hot and dense contents that then begin spiral around the system. In this simulation, scientists placed a mismatched pair of neutron stars, weighing 1.4 and 1.7 solar masses, 11 miles apart and watched the fateful event play out. When neutron stars collide a spectacular event ensues. To put that into perspective, a cubic centimeter of neutron star matter would weigh more than Mount Everest. They’re only city size, around 12 miles (20 kilometers) in diameter, but size isn’t everything and they certainly pack a punch with a mass about 1.4 times that of our Sun. They form when a huge star, around 8 to 30 times the mass of our Sun, explodes in a supernova. Neutron stars are one of several possible endings for a star. This supercomputer simulation, produced by the Albert Einstein Institute, demonstrates what happens when two neutron stars collide and form a black hole. A beautifully elegant visualization of perhaps one of the most ferocious events that can occur in the universe has been released by NASA.
