On August 17, 2017, the Laser Interferometer Gravitational-Wave Observatory detected gravitational waves from a neutron star collision. Within 12 hours, observatories had identified the source of the event within the galaxy NGC 4993, shown in this Hubble Space Telescope image, and located an associated stellar flare called a kilonova. Hubble observed that flare of light fade over the course of 6 days, as shown in these observations taken on August 22, 26, and 28 (insets).

| About The Image | |
| Color Info | This image is a composite of separate exposures made by the WFC3 instrument on the Hubble Space Telescope using two different cameras and filters isolating the light of specific elements or of specific broad wavelength ranges. The color arises by assigning different hues (colors), to each monochromatic image. In this case, the colors are: blue WFC3/UVIS F606W, green WFC3/IR F110W, orange/red: WFC3/IR F160W. |
