原文:
Ridges of glowing interstellar gas and dark dust clouds inhabit the turbulent, cosmic depths of the Lagoon Nebula. Also known as M8, The bright star forming region is about 5,000 light-years distant. But it still makes for a popular stop on 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 stunning, deep view of the Lagoon’s central reaches is about 40 light-years across. Near the center of the frame, the bright hourglass shape is gas ionized and sculpted by energetic radiation and extreme stellar winds from a massive young star.

在宇宙深處，波濤洶湧的拉貢星雲（Lagoon Nebula）內，浮現著閃爍的星際氣體脊和黑暗的塵埃雲。這個被稱為M8的明亮星際形成區域，距離我們約5,000光年。它仍然是望遠鏡遊覽人馬座（Sagittarius）的一個受歡迎站點，朝向我們銀河系的中心。這幅壯觀深邃的圖像顯示了拉貢星雲中央區域的情景，該區域約40光年寬，並以離子氫原子重新結合的紅色發射光譜為主導。在畫面中央，明亮的沙漏形狀是由一顆巨大的年輕恆星所釋放的能量輻射和極端恆星風所離子化和雕琢而成。
