Light from 23 distant galaxies, identified with red rectangles in the Hubble Space Telescope image at the top, was combined to capture incredibly faint emission from eight different elements – hydrogen, helium, nitrogen, oxygen, silicon, sulfur, argon and nickel – which are labelled in the James Webb Space Telescope spectrum at the bottom, in this undated handout illustration.
