一千多年前,波斯天文學家阿卜杜勒·拉赫曼·蘇菲在《恆星書》(牛津大學博德利圖書館藏本MS. Marsh 144 ,第 167 頁)中發表了人類已知關於仙女座星系的最古老記錄。 800 年後,仙女座星系成為查爾斯·梅西耶《星雲與星團目錄》中的第 31 個條目。 從“一小片雲”到“星雲”,再到如今被公認為離我們最近的主要星系,仙女座始終是天文學研究中的基礎天體。這張耗時 202 小時拍攝的影像,展現了我們在觀測這位“鄰居”方面所取得的巨大進步。那些瀰漫的紅藍雲團主要由前景中的電離氫和氧構成,它們完全位於我們的銀河系內部。 被年輕恆星高能光線電離的粉紅色氫氣雲,勾勒出該星系塵埃瀰漫的螺旋臂輪廓。圖中可見M 32 和M 110 這兩顆衛星星系正環繞著更大的仙女座星系執行。儘管從古人肉眼觀測到現代望遠鏡觀測,仙女座星系已有悠久的歷史,但它仍蘊藏著無數秘密,天文學家將繼續探索這些奧秘,包括星系如何合併與演化,以及星系所處的暗物質的本質。 各位老師!NASA/IPAC 教師檔案研究專案現已正式開放申請!
原文:Over 1000 years ago, Persian astronomer Abd al-Rahman al-Sufi published humanity’s oldest known record of the Andromeda Galaxy in "The Book of Fixed Stars" (Bodleian Library MS. Marsh 144 p. 167). 800 years later, Andromeda became the 31st entry in Charles Messier’s "Catalogue of Nebulae and Star Clusters". From “a small cloud” to “nebula” and now known to be our nearest major galaxy, Andromeda has remained a fundamental astronomical object. Today’s image, taken over 202 hours, shows how far we have come in our ability to observe our neighbor. The diffuse red and blue clouds are mostly foreground ionized hydrogen and oxygen well within our Milky Way. Pink-red clouds of hydrogen ionized by the energetic light of young stars trace the galaxy’s dusty spiral arms. M32 and M110 are satellite galaxies pictured orbiting the larger Andromeda. Despite its long history of observation through ancient unaided eyes to modern telescopes, Andromeda still holds countless secrets that astronomers will continue to search for, including how galaxies merge and evolve, as well as the nature of the dark matter that galaxies reside in. Teachers! the NASA/IPAC Teacher Archive Research Program is officially open for applications!
