Musca, the Southern Fly, flits to the south (here to the right) of Crux, the Southern Cross, which lies at the left edge of the picture, the scene here seen rising. Alpha Muscae is the brighter (upper) of the two stars at center. Part of Centaurus lies above Crux, part below, where the bright star at bottom is Hadar, Beta Centauri. Photo by Greg Dimijian.
