Johns Hopkins astrophysicists have spent the past several years working to install one of the most powerful telescopes in the world in a remote mountain location in Chile. Now, all that effort has begun to pay off.

The Cosmology Large Angular Scale Surveyor (CLASS) telescope is designed to be incredibly powerful because it has an incredibly hard job to do: Itโ€™s helping scientists study the origins of the universe by examining the oldest light in the universe, which manifests as a form of cosmic radiation.

CLASS, which was built in Baltimore on Hopkinsโ€™s Homewood campus, has just achieved โ€œfirst light,โ€ according to the Hopkins Hub. Thatโ€™s a lovely way of saying that itโ€™s begun to successfully observe that 13.8 billion year-old cosmic radiation. According to experts, itโ€™ll take about a year of observations โ€“and then plenty of analysisโ€“before CLASSโ€™s data can help further our understanding of how the universe came to be. Much of that work will be done by Hopkins profs, grad students, researchers, and undergrads. Stay tunedโ€ฆ I feel another Nobel prize coming.
