M3 is one of the largest and brightest star clusters, and is made up of around 500,000 stars. It is located at a distance of about 33,900 light-years from Earth, the cluster spans about 220 light-years. It is estimated to be 8 billion years old, making M3 one of the oldest formations in our galaxy. To put that in perspective, this nebula was already half its current age when our own Sun was formed. This image is a 210 minute exposure the nights of May 1 and 2, 2017.
