The Sienna Galaxy Atlas and the dark energy survey are two groundbreaking projects aiming to map and understand the galaxies in the nearby Universe. While the Sienna Galaxy Atlas maps several hundred galaxies, the dark energy survey maps tens of millions of galaxies and quasars, with a focus on understanding the role of dark energy just a billion years after the big bang.
