The Dark Energy Survey uses a 570-megapixel camera mounted on the 4-metre Victor M. Blanco Telescope in Chile to image 5,000 square degrees of southern sky. The survey has already discovered more than 1,000 supernovae and mapped millions of galaxies to help us understand the accelerating expansion of our universe.
