ESO 137-001

ESO 137-001 is a barred spiral galaxy located in the constellation Triangulum Australe and in the cluster Abell 3627. As the galaxy moves to the center of the cluster at 1900 km/s, it is stripped by hot gas, thus creating a 260,000 light-year long tail. This is called ram pressure stripping. The intergalactic gas in Abell 3627 is at 100 million Kelvin, which causes star formation in the tails.
