从哈勃太空望远镜的图像数据中组装的最大的马赛克是我们邻近的螺旋仙女座星系的全景。从2010年7月到2022年12月，哈勃望远镜将600幅重叠的图像拼接在一起，这幅完整的仙女座星系马赛克图像几乎横跨了地球天空的6个满月。上图显示的裁剪版本几乎是两个满月的宽度，部分覆盖了仙女座的核心和内部螺旋臂。仙女座星系也被称为M31，距离我们250万光年。这使得它成为离我们银河系最近的大型螺旋星系。我们对螺旋状银河系的看法是固定在太阳的位置上的，太阳是在银河系的星系盘中发现的一颗恒星。但是哈勃拍摄的美丽的仙女座马赛克照片提供了一个从外部向内看的巨大螺旋星系的广阔视野。哈勃望远镜的全面、详细的数据集横跨仙女座星系，将使天文学家对螺旋星系的结构和进化之谜进行前所未有的全面探索。

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.
