Feature Guest: Marc Kamionkowski

When we study the cosmic microwave background we see our universe before its infancy. But we learn about today’s biggest mysteries, like gravitational waves and supersymmetric dark matter.

Professor Marc Kamionkowski has won a top prize in cosmology for showing us how to “read the subtle bumps and swirls in our images of the early universe” and he joins me at The Star Spot to share secrets from the dawn of time.

Current in Space

Anuj shares discovery of organics in protoplanetary disks of newly formed solar systems. Then following trailers for the upcoming Star Wars film, Tony explains that Tatooine like rocky worlds with twin suns may be out there in the galaxy. Dave shocks us with the possibility of moon caves deep under the lunar surface. And Laura reports that Chiron, a minor planet between Saturn and Uranus known as a centaur, was found to contain rings.
