Fig9_6 Dark clouds Caroina Nebula

Fig. 9.6 . Molecular clouds in the Carina Nebula contain so much gas and dust that they are opaque to optically visible light, forming dark and dense structures where new stars may be born. Energetic stellar winds and intense radiation from nearby massive stars are sculpting the outer edges of the dark clouds. This image is a composite of observations taken in light emitted by hydrogen and oxygen atoms, using the Hubble Space Telescope. The Carina Nebula, also designated NGC 3372, is about 7,500 light-years away from Earth and spans over 300 light-years. (Courtesy of NASA/ESA/Hubble Heritage Project/STScI/AURA.)
