Stellar Explosions and Cosmic ‘Recipe’ for nearby Universe

The Perseus galaxy cluster, located about 240 million light-years away, is shown in this composite of visible light (green and red) and near-infrared images from the Sloan Digital Sky Survey. Unseen here is a thin, hot, X-ray-emitting gas that fills the cluster. Credit: Robert Lupton and the Sloan Digital Sky Survey Consortium

Thanks to an in-depth look into the composition of gas in the Perseus galaxy cluster, Japan’s Hitomi mission has given scientists new insights into the stellar explosions that formed its chemical elements. Before its brief mission ended unexpectedly in March 2016, Japan’s Hitomi X-ray observatory captured exceptional information about the motions of hot gas in the Perseus galaxy cluster...
