From a mountaintop in Chile, the Dark Energy Camera will search for dark energy by photographing infant galaxies.
Cosmic laboratory
Astrophysicists use the cosmos as a laboratory to complement experiments at particle accelerators. Astrophysical observations reveal a universe made mostly of dark matter and dark energy. A combination of underground experiments and ground- and space-based telescopes explores these dark phenomena.
