附近有一个被称为梅西耶17的恒星工厂，距离我们约5500光年，位于星云丰富的人马座。在这个距离上，这个1.5度宽的视场将跨越大约150光年。在这张清晰的彩色合成图像中，该地区的气体和尘埃云的模糊细节被窄带图像数据突出显示，背景是银河系中心的恒星。从M17的宇宙气体和尘埃中形成的热的大质量恒星产生的恒星风和高能辐射慢慢地侵蚀了剩余的星际物质，形成了星云的洞穴状外观和内部的起伏形状。M17也被称为欧米茄或天鹅星云，是望远镜宇宙之旅的热门站点。

A nearby star factory known as Messier 17 lies some 5,500 light-years away in the nebula-rich constellation Sagittarius. At that distance, this 1.5 degree wide field-of-view would span about 150 light-years. In the sharp color composite image faint details of the region's gas and dust clouds are highlighted with narrowband image data against a backdrop of central Milky Way stars. The stellar winds and energetic radiation from hot, massive stars already formed from M17's stock of cosmic gas and dust have slowly carved away at the remaining interstellar material, producing the nebula's cavernous appearance and the undulating shapes within. A popular stop on telescopic tours of the cosmos, M17 is also known as the Omega or the Swan Nebula.
