XRISM Measures a Galactic Wind at the Heart of M82

Astronomers have directly measured superheated gas blasting out of the starburst galaxy M82 at more than 3.2 million kilometers per hour, strengthening the case for a stellar-driven outflow.

Key Takeaways

XRISM measured hot gas in M82 moving outward at more than 3.2 million kilometers per hour.
The gas temperature is reported at about 25 million degrees Celsius.

XRISM Measures the Speed of M82’s Superheated Galactic Wind for the First Time

NASA and JAXA’s XRISM mission has directly measured the speed of superheated gas blasting out of the starburst galaxy M82, offering fresh evidence about what drives galaxy-scale winds.

Key Takeaways

XRISM directly measured superheated gas in M82 moving at more than 2 million miles per hour.
Researchers say the hot outflow appears to drive the galaxy’s larger cool wind.

NASA's XRISM Spacecraft Peers Into the 'Eye of the Storm' Around Supermassive Black Holes

The joint NASA-JAXA X-ray mission XRISM has revealed the most violent turbulence ever detected in a galaxy cluster, centered on the supermassive black hole M87*. The spacecraft's unprecedented ability to measure gas velocities has transformed our understanding of how black holes shape their cosmic surroundings.

Key Takeaways

XRISM detected the most violent turbulence ever recorded in a galaxy cluster, centered on black hole M87*
The spacecraft can measure gas velocities around black holes for the first time, a capability no previous X-ray telescope possessed
