X-ray spectra provide sharpest image to date of a rapidly spinning black hole. High-resolucion spectra from XRISM combined with XMM-Newton and NuSTAR have isolated broad iron emission and reflection features near the iconic supermassive BH in MCG-6-30-15.

During the time of the observations, the comet was about 282–285 million km from the spacecraft. The image shows the comet glowing in low-energy X-rays: blue marks empty space with very few X-rays, while red highlights the comet’s X-ray glow.

Athena was selected as the second large mission of #CosmicVision, and was later rescoped as #NewAthena.

NewAthena will be the largest X-ray observatory ever built. It will investigate some of the hottest & most energetic phenomena in the Universe with unprecedented accuracy and depth.
