High in the Atacama Desert of Northern Chile, in one of the highest and driest places on Earth, sits the Simons Observatory. This incredible facility uses a team of advanced telescopes to capture the oldest light in the cosmos: the Cosmic Microwave Background, which is the leftover glow from the Big Bang itself. By mapping this ancient radiation, the scientists in the Simons Observatory Collaboration are essentially looking back in time to the first moments of the universe. Their goal is to use this data to answer some of the biggest questions in science: How did the universe begin? What exactly is dark matter? What can ghost-like particles called neutrinos tell us about how the cosmos evolved into what we see today? How did galaxies form?
