This image shows Abell in a composite of data with Xrays from Chandra blue and optical data from the VLT gold A huge spiral structure in the hot gas spanning almost a million light years is seen around the outside of the image This spiral was created when a small cluster of galaxies smashed into a larger one that surrounds the central elliptical galaxy The collision caused the hot gas in the cluster to be sloshed back and forth similar to wine sloshing in a glass that was jerked sideways This sloshing has important effects including impacting how the giant elliptical galaxy and its supermassive black hole grow
