ESO 137-001, also known as the Jellyfish Galaxy, is a barred spiral galaxy[2] located in the constellation Triangulum Australe and in the cluster Abell 3627.[6] As the galaxy moves to the center of the cluster at 1900 km/s,[4] it is stripped by hot gas, thus creating a 260,000 light-year long tail.[6] This is called ram pressure stripping.[5] The intergalactic gas in Abell 3627 is at 100 million Kelvin, which causes star formation in the tails.[5][6]
