Messier 67 (M67, NGC 2682) is an open star cluster in the constellation Cancer and is
about 2700 light years away. It is one of the older open clusters known and is estimated
to contain well over 500 stars. Old clusters have mostly yellow and red stars since the hot,
short-lived blue stars have gone supernova relatively early. Still, there are a number of
blue 'stragglers' as they are called visible in the cluster. Were these stragglers captured
from another cluster? Their origins are not understood at the present time.
