Beacons of X-ray Light Animation
Beacons of X-ray Light Animation
NASA's image library records Beacons of X-ray Light Animation.
This image shows a neutron star -- the core of a star that exploded in a massive supernova. This particular neutron star is known as a pulsar because it sends out rotating beams of X-rays that sweep past Earth like lighthouse beacons.
