"Galactic Atlas Reveals 400,000 Nearby Galaxies in Stunning Detail"

The Siena Galaxy Atlas (SGA) has compiled an atlas of nearly 400,000 nearby large galaxies, providing detailed and accurate information on their positions, sizes, shapes, and brightness. The atlas, which covers half of the night sky, is accessible to the public and aims to aid astronomers in studying galactic physics, identifying transient objects, and understanding the distribution of galaxies and their connection to dark matter. The data was collected using digital telescopes and advanced computer analytics, offering unprecedented levels of detail.
