This movie zooms into the constellation Hydra to focus on the galaxy NGC 4993. Within this galaxy, a neutron star collision generated gravitational waves and an associated gamma-ray burst (GRB). It also resulted in a glow called a kilonova that was visible to telescopes including the Hubble Space Telescope. The Hubble images were taken on August 22, 26, and 28, 2017, and show the glow fading over time.
