M67 was discovered before 1779 and rediscovered by Charles Messier in 1780, who included it in his catalogue. A rich cluster (more than 500 stars) on its own and located about 3,000 ly away.

M67 is one of the oldest star clusters known, about 4-5 billion years old. This makes it suitable for studying star evolution. An interesting fact is the presence of “Blue Stragglers” as well as the high proportion (40%) of white dwarfs.
