It is the core of "globular cluster NGC 6362."
Tightly bound by gravity, globular clusters are composed of old stars, which, at around 10 billion years old, are much older than the sun. These clusters are fairly common, with more than 150 currently known in our galaxy, the Milky Way, and more which have been spotted in other galaxies.
NGC 6362 is in the constellation of Ara and about 25 000 light-years from us.
