Explanation:
Globular star cluster
Omega Centauri,
also known as NGC 5139, is some 15,000 light-years away.
The cluster is packed with about 10 million stars
much older than the Sun within a volume about 150 light-years in diameter,
the largest and brightest of 200 or so known
globular
clusters that roam the
halo of our Milky Way galaxy.
Though most star clusters consist of stars with the same age and
composition, the enigmatic Omega Cen exhibits the presence of
different
stellar populations with a spread of ages and chemical abundances.
In fact,
Omega
Cen may be the remnant core of a small galaxy merging with
the Milky Way.
This astronomically sharp
color image of the classic globular cluster
was recorded in March under Chilean skies from
Hacienda Los Andes.
