This colorful view of the Crab Nebula combines data from five telescopes that span nearly the entire electromagnetic spectrum.
The Crab Nebula is the expanding remains of a star that exploded as a supernova in 1054. In 1844, Lord Rosse named the nebula the “Crab” because its tentacle-like structure resembled the legs of the crustacean. Though the Crab has been studied extensively for decades, astronomers still have much to learn about it.
