the Crab Nebula, is the
most famous known
supernova remnant.
According to historical
records, the Chinese
recorded the appearance
of a "guest star" in 1054
AD, probably when the
supernova was first seen
from the earth. The
resulting Crab Nebula
continues to expand at the
amazing rate of almost 50
million miles per day. At
the center of the nebula is
a spinning neutron star
known as a "pulsar."
In 1758 Charles Messier,
a comet hunter, noted the
nebula, prompting him to
compile his now famous
list of deep sky objects in
order that other comet
hunters would not mistake
them for comets -- hence,
the designation M1.
