Webb's NIRCam instrument highlights Gamma-Ray Burst (GRB) 230307A

Caption

This image from NASA’s James Webb Space Telescope NIRCam (Near-Infrared Camera) instrument highlights Gamma-Ray Burst (GRB) 230307A and its associated kilonova, as well as its former home galaxy, among their local environment of other galaxies and foreground stars. The GRB likely was powered by the merger of two neutron stars. The neutron stars were kicked out of their home galaxy and traveled the distance of about 120,000 light-years, approximately the diameter of the Milky Way galaxy, before finally merging several hundred million years later.
