Black hole week is in full swing at this point, and to celebrate, NASA has released stunning observations of the heart of a distant spiral galaxy — as well as the monster supermassive black hole that dwells in that heart.
The observations were conducted by the X-ray Imaging and Spectroscopy Mission (XRISM), led by the Japan Aerospace Exploration Agency (JAXA) with contributions from NASA; they show the center of spiral galaxy NGC 4151.
