A wave spanning 200,000 light-years (about twice the size of our Milky Way Galaxy) is rolling through the Perseus Cluster, according to observations from NASA’s Chandra X-ray Observatory coupled with radio observations and computer simulations. This X-ray image of the hot gas in the Perseus Cluster was made from 16 days of Chandra observations. An oval highlights the location of an enormous wave found to be rolling through the gas.
