The NASA/ESA/CSA James Webb Space Telescope’s NIRCam (Near-Infrared Camera) was able to detect the host galaxy of the fast radio burst called FRB 20240304B, whose location is shown by the white cross. They found it is a small dwarf galaxy actively forming stars. [Image description: A field full of small galaxies of all shapes against the blackness of space. A few bright white stars show 8 prominent diffraction spikes. A small galaxy at lower right is highlighted with a white box. A shaded triangle extends upward to the corners of a larger box showing a zoom in of the region. Two fuzzy, light blue blobs are at centre, with a larger and brighter one at top. Just above the top blob is a white crosshair showing the location where a fast radio burst was detected.]
