英文原文:Explanation: This magnificent extragalactic skyscape looks toward the Andromeda Galaxy, the closest large spiral galaxy to the Milky Way. It also accomplishes a Messier catalog trifecta by including Andromeda, cataloged as Messier 31 (M31) , along with Messier 32 (M32) , and Messier 110 (M110) in the same telescopic field of view . In this frame, M32 is just left of the Andromeda Galaxy's bright core with M110 below and to the right. M32 and M110 are both elliptical galaxies themselves and satellites of the larger spiral Andromdeda. By combining 60 hours of broadband and narrowband image data, the deep telescopic view also reveals tantalizing details of dust lanes, young star clusters, and star-forming regions along Andromeda's spiral arms, and faint, foreground clouds of glowing hydrogen gas. For now , Andromeda and friends are some 2.5 million light-years from our own large spiral Milky Way. 说明： 这幅壮丽的河外星系图像[3]展示了仙女座星系，这是距离银河系最近的大型螺旋星系。 这幅图像同时完成了梅西耶星表的「三重奏」，包含了仙女座星系，编号为梅西耶31（M31）[4]，以及梅西耶32（M32）[5]和梅西耶110（M110）[6]，都在同一望远镜的视野[7]中。 在这个画面中，M32位于仙女座星系明亮内核的左侧，而M110则在下方偏右的位置。M32和M110本身都是椭圆星系，是较大的螺旋星系仙女座星系的卫星星系。通过结合60小时的宽带和窄频图像数据，这幅深邃的望远镜图像也显示了仙女座星系螺旋臂上的尘埃带、年轻星团和恒星形成区域的迷人细节，以及前景中微弱[8]的发光氢气云。 目前[9]，仙女座星系及其伴星系距离我们所在的银河系大约250万光年。
