Hubble and Beyond

The universe is not just expanding; it’s accelerating. Supermassive black holes are hunkered down at the center of our galaxy and just about every other galaxy, too. We talk about these and other big discoveries of the Hubble Space Telescope, now in orbit for 30 years. But two new next-generation telescopes will soon be joining Hubble: the Nancy Grace Roman Space Telescope and the James Webb Space Telescope. Hear what cosmic puzzles they’ll address. Plus, life in a clean room while wearing a coverall “bunny suit”; what it takes to assemble a telescope. Guests: Meg Urry – Professor of physics and astronomy, Director of the Yale Center for Astronomy and Astrophysics, Yale University John Grunsfeld – Former NASA Associate Administrator, and astronaut Kenneth Harris – Senior Project Engineer, Aerospace Corporation   Learn more about your ad choices.
