Messier 68
M68 is a globular cluster at a distance of about 33,000 light-years away from Earth.

The cluster may be undergoing core-collapse, and it displays signs of being in rotation. The cluster may have been acquired by the Milky Way galaxy through accretion from a satellite galaxy. (Source: Wikipedia)
