This is the mess that is left when a star explodes.
The Crab Nebula, the result of a
supernova seen in
is filled with
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 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.
