由恒星风和辐射雕刻而成，被称为梅西耶17的恒星工厂位于大约5500光年远的星云丰富的人马座。在这个距离上，这1/3度宽的视野跨度超过30光年。这张清晰的合成彩色图像突出了该地区的气体和尘埃云的模糊细节，背景是银河系中心的恒星。由M17的宇宙气体和尘埃形成的炽热大质量恒星发出的恒星风和高能光慢慢地侵蚀着剩余的星际物质，形成了洞穴状的外观和起伏的形状。M17也被称为欧米伽星云或天鹅星云。

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.
