Víctor M. Blanco 4-meter Telescope

The Víctor M. Blanco 4-meter Telescope is seen here at night at Cerro Tololo Inter-American Observatory, with trails of stars high above it. On this telescope is the 570-megapixel Dark Energy Camera — one of the most powerful digital cameras in the world. The Dark Energy Camera was designed specifically for the Dark Energy Survey. It was funded by the Department of Energy (DOE) and was built and tested at DOE's Fermilab.
