The result is a 2.5 billion pixel mosaic (a pixel is the smallest unit of color information in a digital image) containing 200 million bright blue stars hotter than the Sun, with other galaxies and cosmic dust in the background. This detailed overview reveals a little more about the history of Andromeda, also known as M31. In the south of the galactic disk there are signs of a merger with smaller galaxies, such as M32, which was absorbed by Andromeda two to three billion years ago. Andromeda, a spiral galaxy like the Milky Way, can be seen with the naked eye from the Northern Hemisphere on a clear day, appearing like a gray oval with a diameter roughly six times larger than the full Moon. It is the most distant object in the Universe that can be seen without a telescope (<em>Astrophysical Journal<\/em>, January 16; <em>Universe Today<\/em>, January 20).<\/p>\n<div id=\"attachment_562591\" style=\"max-width: 1150px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-562591 size-full\" src=\"https:\/\/revistapesquisa.fapesp.br\/wp-content\/uploads\/2025\/09\/RPF-notas-andrometra-2025-03-1140.jpg\" alt=\"\" width=\"1140\" height=\"320\" srcset=\"https:\/\/revistapesquisa.fapesp.br\/wp-content\/uploads\/2025\/09\/RPF-notas-andrometra-2025-03-1140.jpg 1140w, https:\/\/revistapesquisa.fapesp.br\/wp-content\/uploads\/2025\/09\/RPF-notas-andrometra-2025-03-1140-250x70.jpg 250w, https:\/\/revistapesquisa.fapesp.br\/wp-content\/uploads\/2025\/09\/RPF-notas-andrometra-2025-03-1140-700x196.jpg 700w, https:\/\/revistapesquisa.fapesp.br\/wp-content\/uploads\/2025\/09\/RPF-notas-andrometra-2025-03-1140-120x34.jpg 120w\" sizes=\"auto, (max-width: 1140px) 100vw, 1140px\" \/><p class=\"wp-caption-text\"><span class=\"media-credits-inline\">NASA, ESA, B.
