XRISM

XRISM, the X-ray Imaging and Spectroscopy Mission, is a JAXA-NASA observatory with ESA participation. Its cryogenic Resolve spectrometer measures detailed X-ray spectra, while the Xtend imager provides a wider view of the same cosmic environments. These complementary instruments reveal the temperatures, chemical composition, and motions of hot gas around black holes, within galaxy clusters, and in the remnants of stellar explosions. The mission investigates how matter and energy circulate through the universe and how heavy elements are created and dispersed.
