This small but beautiful supernova Remnant (SNR) was the result of the explosion of the star CM Tau, which followed a core-collapse just over 970 years ago.  Located at the centre of the Carb Nebula is the remaining Crab Pulsar neutron star, some 30km in diameter spinning at the rate of 30 times per second.
