About this image

Distance c.1,500ly. Age c.200-250 million years.

On observing the cluster in August 1764, Messier noted:

“I have determined the position of a cluster of small stars between the head of the Medusa and the left foot of Andromeda almost on the parallel of the star Gamma of that letter constellation. With an ordinary refractor of 3 feet, one distinguishes these stars; the cluster may have 15 minutes in extension."
