Very Cold Detectors Reveal the Very Hot Universe and Kick Off a New Era in X-ray Astronomy - NASA Science

X-rays are radiated by matter hotter than one million Kelvin, and high-resolution X-ray spectroscopy can tell us about the composition of the matter and how fast and in what direction it is moving. Quantum calorimeters are opening this new window on the Universe. First promised four decades ago, the quantum-calorimeter era of X-ray astronomy has […]

NASA, JAXA XRISM Mission Looks Deeply Into ‘Hidden’ Stellar System - NASA Science

The Japan-led XRISM (X-ray Imaging and Spectroscopy Mission) observatory has captured the most detailed portrait yet of gases flowing within Cygnus X-3, one of the most studied sources in the X-ray sky. Cygnus X-3 is a binary that pairs a rare type of high-mass star with a compact companion — likely a black hole. “The […]

NASA, JAXA XRISM Spots Iron Fingerprints in Nearby Active Galaxy - NASA Science

After starting science operations in February, Japan-led XRISM (X-ray Imaging and Spectroscopy Mission) studied the monster black hole at the center of galaxy NGC 4151. “XRISM’s Resolve instrument captured a detailed spectrum of the area around the black hole,” said Brian Williams, NASA’s project scientist for the mission at the agency’s Goddard Space Flight Center […]

NASA/JAXA’s XRISM Mission Captures Unmatched Data With Just 36 Pixels - NASA Science

At a time when phone cameras are capable of taking snapshots with millions of pixels, an instrument on the Japan-led XRISM (X-ray Imaging and Spectroscopy Mission) satellite captures revolutionary science with just 36 of them. “That may sound impossible, but it’s actually true,” said Richard Kelley, the U.S. principal investigator for XRISM at NASA’s Goddard […]

NASA/JAXA XRISM Mission Reveals Its First Look at X-ray Cosmos - NASA Science

The Japan-led XRISM (X-ray Imaging and Spectroscopy Mission) observatory has released a first look at the unprecedented data it will collect when science operations begin later this year. The satellite’s science team released a snapshot of a cluster of hundreds of galaxies and a spectrum of stellar wreckage in a neighboring galaxy, which gives scientists […]
