ESO 137-001 is a textbook example of a galaxy that is undergoing stripping by ram pressure: the galaxy and its surroundings were imaged by Hubble; its tail, which traces streams of hydrogen and show up in hues of bright purple, by the MUSE instrument mounted on the VLT; and bright hotspots of carbon dioxide emission from within the system, which show up as flares of orange-red, were spotted by ALMA.
