Japan’s XRISM X-ray observatory has delivered the first detailed maps of hot gas swirling around supermassive black holes in the Virgo and Perseus galaxy clusters. The data reveal intense turbulence, like cosmic storms driven by black hole jets. This churning heats the gas, stopping it from cooling and collapsing into new stars, explaining why cluster cores remain s…​Japan’s XRISM X-ray observatory has delivered the first detailed maps of hot gas swirling around supermassive black holes in the Virgo and Perseus galaxy clusters.
