Explanation:
Globular star cluster 47 Tucanae is a jewel of the southern sky.
Also
known as NGC 104,
it roams the halo of our Milky Way Galaxy along with some 200 other
globular star clusters.
The second brightest globular cluster (after
Omega Centauri)
as seen from planet Earth, 47 Tuc lies about 13,000 light-years away.
It can be spotted with the naked-eye close on the sky to the
Small Magellanic Cloud
in the constellation of
the Toucan.
The dense cluster is made up of hundreds of thousands
of stars in a
volume only about 120 light-years across.
Red giant stars
on the outskirts of the cluster are easy to pick out as yellowish stars in
this sharp telescopic portrait.
Tightly packed globular cluster 47 Tuc is also home to
a star with the closest known
orbit
around a black hole.
