"XRISM Mission Unveils Groundbreaking First Glimpse into the X-ray Universe"

JAXA's X-Ray Imaging and Spectroscopy Mission (XRISM) has provided its 'first light' observations, showcasing its potential to revolutionize our understanding of the Universe. The mission has successfully captured images and spectra of a galaxy cluster and a supernova remnant, revealing the distribution of chemical elements and providing insights into the evolution of the Universe and the structure of spacetime. XRISM is a collaboration between JAXA, NASA, and ESA, with ESA contributing hardware and scientific expertise in exchange for observing time. Despite a minor issue with a filter on the Resolve instrument, the mission is progressing well, with the commissioning phase set to complete by the end of January. Scientists are invited to submit proposals for observations starting from August 2024, promising a new era in high-resolution imaging spectroscopy of cosmic phenomena.
