         Object RCW79
         Comment Residing in the southern constellation of Centaurus is the emission nebula RCW79. It is an active star-forming region that is approximately 70 light years across. In infrared light, the nebula forms the shape of a cosmic bubble of ionised hydrogen gas and warm dust that has been blown over about one million years by the winds and radiation from hot young stars in its center. The expanding nebula itself has triggered new star formation through the expansion into the interstellar gas and dust around it. At visual wavelengths, the bubble like structure appears as a roughly circular cloud shape. RCW79 is approximately 17,200 light-years away.
