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.
