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
the Southern Hemisphere. Light takes about 20,000 years to reach us
from 47 Tuc which can be seen near the SMC in the constellation of
Tucana. Red Giant stars are particularly easy to see in the above
photograph. The dynamics of stars near the center of 47 Tuc are not
well understood, particularly why there are so few binary systems
there.
