   Explanation: A small constellation hiding near the south celestial
   pole, The Chamaeleon boasts no bright stars. Stars are forming within
   its constellation boundaries though, in a complex of dark, dusty
   molecular clouds. Some 500 light-years distant, the Chamaeleon II dark
   nebula inhabits this view where the cosmic dust clouds standout mostly
   in silhouette against the starry southern sky. The telescopic frame is
   about the angular size of a Full Moon and so spans about 5 light-years
   at the dark cloud's estimated distance. Scattered near center a
   telltale reddish glow from identified Herbig-Haro objects is seen in
   the sharp image, jets of shocked glowing gas emanating from recently
   formed stars.
