Giant Hubble Mosaic of the Crab Nebula - Universe Today
The Hubble Space Telescope took this amazing picture of the Crab Nebula supernova remnant. The star at the heart of the nebula exploded as a supernova nearly 1,000 years ago, and was recorded by Chinese astronomers as being bright enough to be visible during the day. This photograph was built up from 24 individual Wide Field and Planetary Camera 2 exposures taken over several years.
