The Deep Lagoon Image Credit & [3]Copyright: [4]Josep Drudis, [5]Christian Sasse Explanation: Ridges of glowing interstellar gas and dark dust clouds inhabit the [6]turbulent, cosmic depths of the Lagoon Nebula. Also known as M8, The bright star forming region is about 5,000 light-years distant. It makes for a popular stop on [7]telescopic tours of the constellation Sagittarius toward the center of our Milky Way Galaxy. Dominated by the telltale red emission of ionized hydrogen atoms recombining with stripped electrons, this [8]deep telescopic view of the Lagoon's central reaches is about 40 light-years across. The bright hourglass shape [9]near the center of the frame is gas ionized and sculpted by energetic radiation and extreme stellar winds from a [10]massive young star.
