M1 - The Crab Nebula

The Crab Nebula in Taurus is the remnant of a supernova explosion in 1054 AD.  In the center of this nebula is a rapidly rotating neutron star.  This neutron star is incredibly dense and compact.  It is only a few km in diameter, about the mass of the sun, and rotates 30 times a sec emitting radio pulses.  This object also possesses extreme magnetic fields.  Notice some filiamentary structure and the faint resemblance to a crab.  This is about 12 minutes of exposure time.
