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. 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.

This visualization depicts the orbits and data swaths of the Landsat 8, Landsat 9, Sentinel 2a, and Sentinel 2b satellites. The satellites appear one at a time with their respective data swaths. As time progresses throughout the visualization, the satellites ‘paint’ the globe with imagery to show how the four spacecraft work together to build a complete picture of the Earth.
