While Jupiter and Saturn have been stealing the headlines lately, this week on “The Cosmic Controversy Podcast,” I’m pleased to welcome planetary astronomer Heidi Hammel to talk about the ice giants Uranus and Neptune. They remain the largely forgotten gatekeepers to our outer solar system.
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.
