The pulsar at the heart of the famous Crab nebula is bursting with energy. This was just confirmed by the MAGIC (Major Atmospheric Gamma-Ray Imaging Cherenkov) collaboration operating two large telescopes on the Canary island La Palma. The MAGIC telescopes have been used to observe the pulsar in gamma rays above 50 GeV, an inaccessible energy for most high energy instruments, and have detected periodic pulsed emission at energies as high as 400 GeV. This is 50-100 times higher than predicted by current theoretical models.
