M1: The Crab Nebula from NOT
Credit & Copyright: Walter Nowotny (U. Wien, Nordic Optical Telescope
Explanation: This is the mess that is left when a star explodes. The Crab
Nebula, the result of a supernova seen in 1054 AD, is filled with mysterious
filaments. The filaments are not only tremendously complex, but appear to
have less mass than expelled in the original supernova and a higher speed
than expected from a free explosion. The above image, taken by the Nordic
Optical Telescope (NOT), is in three colors chosen for scientific interest.
The Crab Nebula spans about 10 light-years. In the nebula's very center lies
a pulsar: a neutron star as massive as the Sun but with only the size of a
small town. The Crab Pulsar rotates about 30 times each second.
