Scientists have embarked on a quest to map one-eighth of the entire sky looking for clues about dark energy, the mysterious force believed to be responsible for the ever-accelerating expansion of the universe.
The five-year Dark Energy Survey (DES for short) officially began after sunset on Aug. 31, 2013. Its main instrument is the 570-megapixel Dark Energy Camera at the Cerro Tololo Inter-American Observatory in the Andes Mountains in Chile.

Though scientists think dark energy comprises 74 percent of the universe, they do not fully understand what it is. Dark energy, for now, is the name given to the force that seems to be working against gravity, causing the expansion of the universe to speed up instead of slow down.
