![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.](https://science.nasa.gov/wp-content/uploads/2023/09/Neutron_Star_Merger.jpeg?w=4096&format=jpeg)
