The hot gas in the galaxy cluster Abell 2052 is being sloshed back and forth. The sloshing was set in motion when a small cluster smashed into the larger central one. The large spiral structure on the outside of the image was also caused by that off-center collision. Sloshing of hot gas like this can affect how the giant elliptical galaxy and its supermassive black hole at the center grow. X-ray: NASA/CXC/BU/L.Blanton; Optical: ESO/VLT
