Globular Cluster 47 Tucanae from SALT
Explanation: Stars come in bunches. Of the over 200
globular star clusters
that orbit the center of our
Milky Way Galaxy
,
47 Tucanae
is the second brightest globular cluster, behind
Omega Centauri
. Known to some affectionately as 47 Tuc or NGC 104, it is only visible from Earth's
Southern Hemisphere
. It was therefore a fitting target for
first light observations
of the gigantic new 10-meter diameter
Southern African Large Telescope
(SALT) this past week. The resulting image is
shown above
. Light takes about 20,000 years to reach us from
47 Tuc
which can be seen near the
Small Magellanic Cloud
toward the
constellation
of
Tucana
. The dynamics of stars near the center of
47 Tuc
are not well understood, particularly why there are so few
binary systems
there.
