One of the most impressive globular clusters in the sky, almost visible with the naked eye.

It is about 26000 light years away in constellation Serpens and contains several million stars.
Its oldest stars are more than 12 billion years old making M 5 one of the oldest objects in our Milky Way galaxy. Surprisingly it also contains quite a number of young stars. The mechanism of their creation is not yet fully understood. Globular clusters usually do not contain a lot of cold gas, which is usually required to form stars from scratch. Stellar interactions or even star collisions however might be responsible for creation of these blue stragglers.
In my location M 5 is pretty low in the south and therefore only visible for a few hours.
