Episode 30 — Uranus and Neptune — Our Solar System’s Mysterious Ice Giants

December 23, 2020

Renowned planetary astronomer Heidi Hammel and I chat about our solar system’s mysterious ice giant planets, Uranus and Neptune.  There’s only been one flyby of these giant planets by NASA’s Voyager 2 spacecraft back in the late 1980s.  Hammel, who was part of the Voyager 2 science team, explains what that mission taught us about these objects and why we need to go back.
