Galaxies die earlier than expected

Caption

Three spectra taken by the JWST/NIRSpec superimposed on an image taken by the JWST/NIRCam, two instruments on board the James Webb Space Telescope. The record galaxy is shown in the middle. It appears in red in the image and its spectrum decreases towards the left (short wavelengths). For comparison, the spectra at the top and bottom, in blue and violet, show typical star-forming galaxies at a similar time in cosmic history.
