哈勃的仙女座星系馬賽克圖
Hubble's Andromeda Galaxy Mosaic

發表日期:2025-02-21
由哈勃太空望遠鏡影像資料拼成的有史以來最大的馬賽克照片是我們相鄰的螺旋仙女座星系的全景圖。從 2010 年 7 月到 2022 年 12 月,哈勃太空望遠鏡觀測到的仙女座星系全景圖有 600 個重疊幀,幾乎橫跨地球天空的六個滿月。上圖是經過裁剪的版本,寬度接近兩個滿月,部分覆蓋了仙女座的核心和內旋臂。仙女座星系也被稱為 M 31 ,距離地球 250 萬光年。這使它成為離我們銀河系最近的大型螺旋星系。我們對螺旋狀銀河系的觀察視角是固定在太陽的位置上的,太陽是銀河系盤中的一顆恆星。但是,哈勃的仙女座馬賽克壯麗圖景提供了一個從外向內觀察大型螺旋星系的廣闊視角。哈勃的全面、詳細的資料集橫跨仙女座星系,將使天文學家對螺旋星系結構和演化的奧秘進行前所未有的整體探索。
原文:The largest photomosaic ever assembled from Hubble Space Telescope image data is a panoramic view of our neighboring spiral Andromeda Galaxy. With 600 overlapping frames assembled from observations made from July 2010 to December 2022, the full Hubble Andromeda Galaxy mosaic spans almost six full moons across planet Earth's sky. A cropped version shown above is nearly two full moons across and partially covers Andromeda's core and inner spiral arms. Also known as M31, the Andromeda Galaxy is 2.5 million light-years away. That makes it the closest large spiral galaxy to our own Milky Way. Our perspective on the spiral Milky Way is anchored to the view from the location of the Sun, a star found within the Milky Way's galactic disk. But Hubble's magnificent Andromeda mosaic offers an expansive view of a large spiral galaxy from the outside looking in. Hubble's comprehensive, detailed data set extending across the Andromeda Galaxy will allow astronomers to make an unprecedented holistic exploration of the mysteries of spiral galaxy structure and evolution.
