Caldwell 1 NGC 188.jpg

Caldwell 1 is an open cluster some 4,800 light years away. It was discovered by Herschel in 1825. This open cluster is interesting as it is thought to be extremely ancient, but hasn't moved apart as other open clusters tend to. This is because it is above the plane of the galaxy and so resists the gravitational interaction with the galaxy.
