M13

Messier 13 is globular cluster conformed by several hundred of thousands of stars. Also known as NGC 6205 or Great Hercules Cluster, it is located in constellation of the same name at around 25.000 years light away from Earth. It is about 145 light-years in diameter, with an estimation of 300-000 - 1 million stars conforming it.

 

A globular cluster is a conglomeration of stars that are bounded together through gravity. It results in a spherical global shape, being the center of the cluster the area with more stars concentration. It is supposed that the stars of a globular clusters were born around the same period of time, probably in a very early time of our Milky Way, around the massive halo surrounded the young galaxy. So, the stars of a globular cluster are supposed to be very old (10.000-13.000 million years), becoming great objects to get potential clues about the very early times of our galaxy.
