Astronomers have created a detailed atlas of almost 400,000 galaxies in our cosmic neighborhood. The Siena Galaxy Atlas was compiled using data from NSF's NOIRLab telescopes, and is designed to be the preeminent digital galaxy atlas for large galaxies. It's a treasure trove of information for researchers investigating everything from galaxy formation and evolution to dark matter and gravitational waves. It's also freely available online for the public to explore.
