Planetary Radio: Space Exploration, Astronomy and Science

The Skies of Super-Earths and Mini-Neptunes

There appear to be more mini-Neptunes (also known as Super Earths) across our galaxy than any other type of planet.  Hannah Wakeford wants to learn if some of them support life, and she’s doing this by exploring their skies. Curiosity, the Mars Science Laboratory rover, has reached an exciting and critical part of its mission of discovery. Senior editor Emily Lakdawalla provides an update. The beautiful Pasadena Public Library hosted Bruce Betts and Mat Kaplan for a special afternoon that included recording this week’s What’s Up.
