Hand of God pulsar wind nebula. Composite image showing the pulsar wind nebula nicknamed the 'Hand of God'. This cloud of material was ejected from a star that blew up in a supernova explosion. The dead remains of the star at the centre (not visible) is a pulsar named B1509 (PSR B1509-58), which fires out a particle wind into the material around it. These particles are interacting with magnetic fields around the material, causing it to glow with X-rays. Image composed of high-energy X-ray data from NASA's Nuclear Spectroscopic Telescope Array (NuSTAR, blue) and lower-energy X-ray data from the Chandra X-ray Observatory (green and red).
