This is the largest photomosaic ever assembled from Hubble Space Telescope image data. It is a panoramic view of our neighboring spiral Andromeda Galaxy. It consists of 600 overlapping frames assembled from observations made from July 2010 to December 2022. A cropped version of the mosaic, which is shown above, partially covers Andromeda's core and inner spiral arms. Also known as M31, the Andromeda Galaxy is 2.5 million light-years away, making it the closest large spiral galaxy to our own. Hubble's comprehensive, detailed data set extending across the Andromeda Galaxy will allow astronomers to make an unprecedented exploration of the mysteries of spiral galaxy structure and evolution.
