This view shows how the new MUSE instrument on ESO’s Very Large Telescope gives a three-dimensional view of a distant galaxy. For each part of the galaxy the light has been split up into its component colours — revealing not only the motions of different parts of the galaxy but also clues to its chemical composition and other properties. At certain wavelengths the emission from the rotating disc around the galaxy is clearly seens, as well as the different velocities of different parts of the disc.
