A major X-ray observing mission is set to launch on Saturday (Aug. 26), aiming to provide astronomers with views of some of the universe's most extreme, explosive and hot objects and events.
The X-Ray Imaging and Spectroscopy Mission (XRISM), a collaboration between NASA and the Japanese Aerospace Exploration Agency (JAXA) with assistance from the European Space Agency (ESA), will study things like hot gas envelopes surrounding galaxy clusters and violent outbursts from monster black holes. Its results should help scientists better understand the evolution of the universe.
