The Trifid Nebula, also known as Messier 20, is easy to find with a small telescope, a well known stop in the nebula rich constellation Sagittarius. But where visible light pictures show the nebula divided into three parts by dark, obscuring dust lanes, this penetrating infrared image reveals filaments of glowing dust clouds and newborn stars. The spectacular false-color view is courtesy of the Spitzer Space Telescope. Astronomers have used the Spitzer infrared image data to count newborn and embryonic stars which otherwise can lie hidden in the natal dust and gas clouds of this intriguing stellar nursery. As seen here, the Trifid is about 30 light-years across and lies only 5,500 light-years away.

📸✨ 三裂星雲（Trifid Nebula），亦稱為梅西耶20（Messier 20），係一個喺人馬座（Sagittarius）嘅星雲。用小型望遠鏡都可以輕易找到佢。雖然可見光圖片顯示星雲被黑暗嘅塵埃帶分成三個部分，但這幅深入紅外線影像則揭示出發光嘅塵雲線條同埋新誕生嘅恆星。這幅壯觀嘅假色圖係來自斯匹斯太空望遠鏡（Spitzer Space Telescope）。天文學家利用呢幅紅外線影像數據來計算新生及胚胎恆星，因為佢哋通常隱藏喺這些星形成雲氣同塵埃中。正如圖中所示，三裂星雲約有30光年闊，距離地球僅5,500光年。
