The objects vary in color: white, blue-white, yellow-white, and orange-red. Toward the center right is a blue-white spiral galaxy seen face-on that is larger than the other light sources in the image. The galaxy is labeled “former home galaxy.” Toward the upper left is a small red point, which has a white circle around it and is labeled “GRB 230307A kilonova.” Zoom Image PaginationPrevious2 of 3Next About This Image Release Date October 25, 2023 11:00AM (EDT) Read the Release Release ID: 2023-134 Permissions Content Use Policy Download Options Full Res Main, 2525 X 1561, TIF (4.90 MB) Full Res Main, 2525 X 1561, PNG (4.05 MB) Crop Main, 2000 X 1236, PNG (2.57 MB) Full Res Wide, 4316 X 2826, TIF (15.31 MB) Full Res Wide, 4316 X 2826, PNG (12.50 MB) Wide, 2000 X 1310, PNG (3.01 MB) Caption A team of scientists has used NASA’s James Webb Space Telescope to observe an exceptionally bright gamma-ray burst, GRB 230307A, and its associated kilonova. Kilonovas—an explosion produced by a neutron star merging with either a black hole or with another neutron star—are extremely rare, making it difficult to observe these events. The highly sensitive infrared capabilities of Webb helped scientists identify the home address of the two neutron stars that created the kilonova. This image from Webb’s NIRCam (Near-Infrared Camera) instrument highlights GRB 230307A’s kilonova and its former home galaxy among their local environment of other galaxies and foreground 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. |
