The Cosmic Frontier reveals the nature of dark matter and dark energy by using particles from space to explore new phenomena. Cosmic rays in the earth’s atmosphere, neutrinos from the sun, and gamma rays from deep space, are some of the known natural sources. Searches are also underway for alternate explanations of dark matter and energy. Observations of the Cosmic Frontier reveal a universe far stranger than ever thought possible. The new techniques at the cosmic complement the accelerator-based research of the other frontiers.
The Office of High Energy Physics supports the following facilities and experiments at the cosmic frontier:
- Dark Energy
- Dark Matter
- Cosmic-ray, Gamma-ray
