This sharp Hubble Space Telescope view looks
into NGC 6752.
Some 13,000 light-years away toward the southern constellation Pavo,
the globular star cluster
roams the halo of our Milky Way galaxy.

stars which appear to be too young and massive to exist
in a cluster whose stars are all expected
to be at least twice as old as the Sun.

a remarkable fraction of the stars near the cluster's core,
are multiple star systems,
