Listen! 'Superheavy' neutron star merger's audio jumps 'thousands of hertz' in simulation

See a pair of superheavy neutron stars collide in this simulation with gravitational wave audio. "An audible tone and a visual frequency scale (at left) track the steady rise in the frequency of gravitational waves as the neutron stars close," according to NASA's Goddard Spaceflight Center.
