"Unveiling the Secrets of 400,000 Galaxies: A Spectacular Galactic Atlas"

A new digital atlas called the Siena Galaxy Atlas (SGA) provides precise details of nearly 400,000 galaxies in the Milky Way's vicinity, offering a wealth of galactic information for astronomers. The atlas features beautiful images and accurate data captured by state-of-the-art digital instruments, making it a valuable resource for studying the formation and evolution of galaxies, the distribution of dark matter, and the propagation of gravitational waves. The SGA is the first cosmic atlas to include light profiles of galaxies, providing a comprehensive view of their brightness. This publicly accessible atlas will have a significant impact on astronomical research and the public's ability to explore and identify nearby galaxies.
