The Old and the Young

M 35 and NGC 2158, LRGB

January 23rd, 2018

Object details:

The magnificent young open cluster M 35 is an amazing visual target, and displays wonderful colors in an image. The young blue stars are rapidly burning through their fuel and will eventually become red giants and supergiants that will end their lives in supernovae. The small cluster to the right is known as NGC 2158, and was once thought to be a distant globular cluster. Recent research has shown that this is actually an old, metal deficient, open cluster.
