Summary

[edit]
Description
English: Located in the constellation of Taurus, the Crab nebula is the remnant of a supernova formed from the explosion of a massive star a thousand years ago in 1054. Most elements on Earth are produced by supernova explosions. About thirty elements in the periodic chart have been detected in the interstellar medium. Supernova such as the Crab have produced the interstellar oxygen and neon atoms that are observed by IBEX
