原文:
Sculpted by stellar winds and radiation, the star factory known as Messier 17 lies some 5,500 light-years away in the nebula-rich constellation Sagittarius. At that distance, this 1/3 degree wide field of view spans over 30 light-years. The sharp composite, color image, highlights faint details of the region’s gas and dust clouds against a backdrop of central Milky Way stars. Stellar winds and energetic light from hot, massive stars formed from M17’s stock of cosmic gas and dust have slowly carved away at the remaining interstellar material producing the cavernous appearance and undulating shapes. M17 is also known as the Omega Nebula or the Swan Nebula.

雕刻於恒星風和輻射之中，這個被稱為 M17 的星際工廠位於距離地球約 5,500 光年的星雲豐富的射手座中。以這個距離來看，這個 1/3 度寬的視場橫跨超過 30 光年。這幅清晰的合成彩色圖像突顯了該地區氣體和塵埃雲的微弱細節，並以中心銀河的恆星作為背景。來自 M17 中熱量和質量巨大的恆星所產生的恒星風和強烈光線，逐漸雕刻出剩餘的星際物質，形成了奇特的洞穴狀外觀和起伏的形狀。M17 也被稱為 Omega Nebula 或 Swan Nebula。
