CLASS will image the cosmic microwave background, detecting patterns from the early inflation of the universe and the formation of stars and galaxies. CLASS will map more than 70% of the sky.
Demonstrated a novel signal modulation technique in an effort to reduce systemic errors to improve data quality and fidelity.
At 5,200 meters (17,000 feet), it's one of the highest telescopes in the world. The high and dry site limits the negative impacts of microwave emissions from water and oxygen molecules in the atmosphere.
