- Object Information:
- Messier 1 is the first object cataloged by Charles Messier and is an expanding cloud of gas which was created when a star exploded as a supernova. Chinese astronomers noted the supernova explosion which created this object on July 4, 1054 A.D. It is reported that the supernova was visible during the day for twenty-three days. This nebulous supernova remnant was first noted by John Bevis in 1731 and was later independently "discovered" by Charles Messier in 1758. More on Messier 1 and Charles Messier can be found at: http://www.seds.org/messier/m/m001.html
- The approximate size of the Messier 1 supernova remnant is 10 light years in diameter and it is continuing to expand at at rate of 1,800 km/sec.
