M1: The Crab Nebula from Hubble
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
featured image, taken by the
Hubble Space Telescope, is presented 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.
