Hubble Space Telescope image of gamma-ray burst (GRB) 211211A (red circle). This GRB was observed on the 11th December 2021 and was located in the constellation Bootes, approximately 1 billion light-years away. GRBs are high energy explosions that can either be long burst, lasting two seconds or more, or short burst, lasting less than two seconds. It was previously thought that long burst GRBs resulted from the collapse of massive stars, while short burst GRBs resulted from the merger of two dense objects, such as neutron stars. GRB 211211A was the first observed long burst GRB originating from the merger of two neutron stars. This image was captured by the Hubble Space Telescope with its Wide Field Camera 3 and Advanced Camera for Surveys.
