APOD 4.5

Hubble's Messier 5
This is an image of Messier 5 (M5) which is a globular star cluster of about 100,000 stars or more. The region is about 165 light-years in diameter and the stars are bounded by gravity. M5 is about 25,000 light years away from us and it roams the halo of our galaxy. It's one of the oldest globular clusters and it has very old stars toward the dense core and gives off a reddish hue. This is a really awesome image and gives off cool colors.
