This image depicts a gamma-ray burst caused by the merger of two neutron stars. The merger creates gravitational waves (shown as pale arcs rippling outward) being created following the merger of two neutron stars, 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. A variety of colors represent the wavelengths of light produced by the kilonova, creating violet to blue-white to red bursts above and below the collision.

At the beginning of this animated GIF, we see the glowing gas surrounding two black holes. The gas is shaded orange and purple, and it is tightly wound around each individual black hole. They each have a tail of gas, looking like a comma. As the animation proceeds, the camera moves to see the two black holes nearly in line with each other and then back to see the bottom of the system. As the view tilts, the gravitational effects of the black holes at the center cause the light to bend like a funhouse mirror.
