The mysterious cosmic microwave background (CMB), the oldest light in the universe, has been traveling through space since just after the Big Bang. Although invisible to our eyes, capturing this ancient light could unlock secrets about how our universe formed and evolved over billions of years.

Recent groundbreaking measurements from the South Pole Telescope, located at the National Science Foundation's Amundsen-Scott Station, promise to transform our understanding of cosmology. Utilizing an upgraded camera, researchers have achieved unprecedented sensitivity in their observations, revealing intricate details about the cosmic microwave background that surpass previous studies, including those conducted in space.

On June 25, scientists announced these remarkable findings, marking what Tom Crawford, deputy director of the telescope and research professor at the University of Chicago, described as "a watershed moment for cosmic microwave background cosmology." This milestone signals the dawn of a new era where ground-based experiments will significantly advance our comprehension of the universe.
