這幅壯麗的河外星系天景,望向仙女座星系,它是距離銀河系最近的大型旋渦星系。它還完成了梅西耶星表的三連冠,將仙女座星系(星表編號為梅西耶 31 (M 31 ))、梅西耶 32 (M 32 )和梅西耶 110 (M 110 )包含在同一個望遠鏡視場中。 在這幅圖中,M 32 位於仙女座星系明亮核心的左側,M 110 在其下方和右側。M 32 和 M 110 本身都是橢圓星系,也是更大的螺旋星系仙女座的衛星。透過結合 60 小時的寬頻和窄帶影像資料,這臺深度望遠鏡的檢視還揭示了仙女座旋臂沿線的塵埃通道、年輕星團和恆星形成區的誘人細節,以及微弱的前景氫氣雲。目前,仙女座和它的朋友們距離我們自己的大螺旋銀河系大約有 250 萬光年。
原文: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.
