Astronomy Picture of the Day [1]Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2024 May 27 [2]See Explanation.

Chamaeleon I Molecular Cloud Image Credit & [3]Copyright: [4]Amiel Contuliano Explanation: [5]Dark markings and bright nebulae in this telescopic southern sky view are telltale signs of young stars and [6]active [7]star formation. They lie a mere 650 light-years away, [8]at the boundary of the [9]local bubble and the Chamaeleon molecular cloud complex. Regions with young stars identified as dusty reflection nebulae from the 1946 [10]Cederblad catalog include the C-shaped Ced 110 just above and right of center, and bluish Ced 111 below it. Also a standout in the frame, the orange tinted V-shape of the [11]Chamaeleon Infrared Nebula (Cha IRN) was carved by material streaming from a newly formed low-mass star. [12]The well-composed image spans 1.5 degrees. That's about 17 light-years at the estimated distance of the nearby [13]Chamaeleon I molecular cloud.
