This animation shows what happened in the nine days after a neutron star merger detected in 2017. First, a pair of glowing blue neutron stars spiral quickly toward each other, merging with a bright flash. The merger creates gravitational waves (shown as pale arcs rippling outward), a near-light-speed jet that produced gamma rays (shown as brown cones and a rapidly traveling magenta glow erupting from the center of the collision), and a donut-shaped ring of expanding blue debris around the center of the explosion.
