Small Magellanic Cloud & 47 Tucanae

Small Magellanic Cloud & 47 Tucanae

The Small Magellanic Cloud is a companion galaxy to our much larger Milky Way galaxy. At a distance of some 200,000 light years, it is perhaps the most distant object visible to the unaided eye. The SMC may have been a barred galaxy at one time, but it is now an irregular and is likely being pulled apart by the Milky Way.

47 Tucanae is the largest globular cluster in the sky, and a showpiece celestial object since it appears to be about the size of the Full Moon under ideal condition. The only brighter globular cluster is Omega Centauri. Both globular clusters are only visible from the southern hemisphere.
