The Crab Pulsar, a city-sized, magnetized
neutron star spinning 30 times a second,

The deep x-ray image gives the first
clear view of
the convoluted boundaries of the Crab's pulsar wind nebula.

The pulsar's energy accelerates
charged particles, producing eerie, glowing x-ray jets directed
away from the poles and an intense wind in the equatorial direction.
Intriguing edges are created as the charged
particles stream away, eventually losing energy as they interact
with the pulsar's strong magnetic field.
With more mass than the Sun and the density of an

estimated distance of 6,000 light-years.
