在浩瀚的星空中，有一個名叫M24的特別地方。它不是一顆明亮的星星，也不是一個星團或星雲，而是一片小小的空隙。這個空隙透過一些距離很近的星際塵埃雲，讓我們能夠看到遙遠的星星，它們在銀河系的射手座螺旋臂中閃耀著光芒。想像一下，透過雙筒望遠鏡或小型望遠鏡，你就像透過一扇300光年寬的窗戶，看到遠在1萬光年之外的星星。M24有時被稱為小射手星雲，這裡的星星像珍珠一樣亮麗，展現在這個美麗的星際場景中。這片天空的範圍大約是四個滿月那麼大，朝向射手座的方向，還能看到B92和B93這兩個黑色的標記，還有其他的塵埃雲和發光的星雲，這些都在銀河系的中心附近。
原文:
Unlike most entries in Charles Messier’s famous catalog of deep sky objects, M24 is not a bright galaxy, star cluster, or nebula. It’s a gap in nearby, obscuring interstellar dust clouds that allows a view of the distant stars in the Sagittarius spiral arm of our Milky Way galaxy. Direct your gaze through this gap with binoculars or a small telescope and you are looking through a window over 300 light-years wide at stars some 10,000 light-years or more from Earth. Sometimes called the Small Sagittarius Star Cloud, M24’s luminous stars stretch across this gorgeous interstellar scene. Spanning over four full moons on the sky toward the constellation Sagittarius, the telescopic field of view includes dark markings B92 and B93 near the center of M24, along with other clouds of dust and glowing nebulae toward the center of the Milky Way.
