Crab Nebula formed in a supernova explosion observed in 1054. At its heart lies an isolated neutron star, the crushed core of the original star. It spins about 30 times a second, sweeping a beam of radiation toward Earth with every rotation, lighthouse style, which classifies the neutron star as a pulsar. This rapid spin powers X-ray jets (elongated blue-white feature near center) and a high-speed outflow of electrons and other particles. The particles collect in a vast cloud-like structure called a pulsar wind nebula, which also forms around magnetars, the pulsar’s supermagnetized cousin. This emission gradually slows the neutron star’s spin. These images combine X-ray data from NASA’s Chandra X-ray Observatory (bluish white) and infrared data from NASA’s James Webb Space Telescope.Credit: X-ray, Chandra: NASA/CXC/SAO; Infrared, Webb: NASA/STScI; Image Processing: NASA/CXC/SAO/J.

Its outer edges are formed by gray, red, and yellow loops and tendrils, parts of which seem to be outward-moving splashes and rivulets of color. The inner area is filled with a faint bluish glow that brightens toward the center. Brighter bluish-white rings make up a kind of bull’s-eye surrounding the pulsar, and an elongated structure curves diagonally downward.
