Marketplace Tech With Molly Wood

NASA’s Hubble Space Telescope has been exploring the cosmos for the past three decades, helping scientists understand how fast the universe is expanding and with that, its age. In December 2021, NASA launched the James Webb Space Telescope to further that research. The bonus: All those stunning images from outer space. Marketplace’s Lily Jamali spoke with Adam Riess, a physicist at Johns Hopkins University who shared the 2011 Nobel Prize in physics. He said the Webb telescope has confirmed what Hubble first pieced together: Our universe is expanding faster than first predicted.
