Royalty-free NASA stock photo of the Crab Nebula (NGC 1952), an example of a supernova remnant. This nebula is a six-light-year-wide expanding remnant of a star’s supernova explosion. The orange filaments are the tattered remains of the star and consist mostly of hydrogen. The rapidly spinning neutron star embedded in the center of the nebula is the dynamo powering the nebula’s eerie interior bluish glow. The blue light comes from electrons whirling at nearly the speed of light around magnetic field lines from the neutron star. The neutron star, like a lighthouse, ejects twin beams of radiation that appear to pulse 30 times a second due to the neutron star’s rotation. A neutron star is the crushed ultra-dense core of the exploded star. Photo Credit: NASA, ESA and Allison Loll/Jeff Hester (Arizona State University) [0003-0710-2121-4834] by 0003
