Japan’s XRISM Telescope Delivers Insights from a Supermassive Black Hole and a Supernova
XRISM also studied a supernova remnant, N132D, located in the Large Magellanic Cloud. This material was ejected by a massive star approximately 3,000 years ago. The telescope's observations revealed that the debris expanded in a non-uniform, donut-shaped structure, rather than the spherical shell previously thought.
