The Siena Galaxy Atlas (SGA) is an online archive that provides images and information about outer space. It covers a significant portion of the universe with 383,620 galaxies. The atlas is free for anyone to browse, but it is more geared towards astronomers and scientists. It allows users to find locations, shapes, and sizes of nearby large galaxies. The data from the DESI Legacy Surveys has made the SGA accurate and valuable for observing specific parts of the galaxy or studying samples from multiple galaxies. The SGA not only has scientific utility but also offers beautiful galaxy pictures for everyone to enjoy.
