Summary[edit]

Description
English: Spectra also tell us an immense amount about galaxies, including very distant galaxies as they existed in the early universe. In the graphs below, we’ve plotted the light gathered from three spiral galaxies. The large black arrows at the left of each spectrum emphasize how far the light from each galaxy has redshifted, or stretched into longer, redder wavelengths due to the expansion of the universe, before reaching the telescope.
