这幅壮丽的河外星空图朝向仙女座星系，它是离银河系最近的大型螺旋星系。它还完成了一个梅西耶星表三连体，包括仙女座星系，编目为梅西耶31 (M31)，与梅西耶32 （M32）和梅西耶110 （M110）在同一个望远镜视野中。在这幅图中，M32位于仙女座星系明亮核心的左侧，M110位于其下方和右侧。M32和M110本身都是椭圆星系，是较大的螺旋仙女座星系的卫星星系。通过结合60小时的宽带和窄带图像数据，深望远镜视图还揭示了仙女座螺旋臂上的尘埃带、年轻星团和恒星形成区域的诱人细节，以及暗淡的、前景的发光氢气云。目前，仙女座星系和它的朋友们距离我们的大螺旋银河系大约250万光年。

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 Andromeda. 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.
