Chamaeleon II Dark Cloud Image Credit & [3]Copyright: [4]Don Goldman Explanation: A small constellation hiding near the [5]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 [6]Chamaeleon II dark nebula inhabits this view where the cosmic dust clouds standout mostly in silhouette against the starry southern sky. [7]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 [8]Herbig-Haro objects is seen in the sharp image, jets of shocked glowing gas [9]emanating from recently formed stars.
