The XRISM (X-ray Imaging and Spectroscopy Mission) space telescope, a collaboration between JAXA, NASA, and ESA, has delivered its first extraordinary observations since its launch in 2023. These ...

Inclement weather postponed the launch of the Japan Aerospace Exploration Agency’s X-ray satellite to study extreme cosmic objects and a lunar lander nicknamed the “Moon Sniper” on Sunday ...

With Chandra's fate uncertain, XRISM carries the hopes of X-ray astronomers across the globe — but a technical issue is holding it back from achieving its full potential.

XRISM will observe X-rays released by extreme phenomena to assist scientists in studying our universe's evolution.

XRISM X-ray telescope launches this week to study the chaotic universe The new observatory will open a new door on the high-energy cosmos as it investigates black holes, galaxy clusters, and more.

The telescope will help astronomers study some of the most energetic places in the cosmos, while the lunar mission will aid the development of pinpoint moon landing technologies.

The first results from JAXA's XRISM X-ray telescope are out, and they reveal new features of the superheated gas around a distant supermassive black hole and a closer supernova.

XRISM could change the way we see the X-ray universe, but a jammed door presents a mighty challenge. With the door closed, low energy X-rays are impossible to detect. But trying to open the door ...
