M1 is also known as the Crab Nebula. It is a remant of a supernova that occured in 1054 AD. The central star is actually a rotating neutron star and is called a pulsar. This exposure was taken through a narrow band H-alpha filter to make the filamentary structure stand out somewhat.

http://hubblesite.org/newscenter/archive/releases/1996/22/text/ Probing the mysterious heart of the Crab Nebula, the tattered remains of a stellar cataclysm witnessed more than 900 years ago, astronomers using NASA's Hubble Space Telescope have found that the Crab is even more dynamic than previously understood, based on a cosmic "movie" assembled from a series of Hubble observations. ... Because of this flickering, the neutron star is also called a "pulsar." ...
