This video pans across the sky near to spiral galaxy ESO 137-001 in the constellation of Triangulum Australe (The Southern Triangle), ending on a view of the galaxy itself. This delicate and beautiful spiral galaxy is undergoing ram pressure stripping, where streaks of bright gas are being dragged out into space by the cluster it is moving through.
