Ice, Snow and Lava: Exploring Antarctica’s Mount Erebus
On This Episode
Senior Research Scientist/Manager for Planetary Science for Jet Propulsion Laboratory
Apollo 17 Commander for NASA
Astrophysicist and Curator for Griffith Observatory
Earth’s southernmost active volcano may also be its most remote. Rosaly Lopes and Michael Carroll recently spent a few frigid days on the slopes of Antarctica’s Mount Erebus. What they learned may help us understand volcanoes on other worlds. Emily Lakdawalla shows us stunning new, close-up images of Saturn’s rings. Bill Nye says a LightSail solar sail prototype has gone on display in a London museum. How could black holes help answer a space trivia contest question about Earth and Saturn? Also, an encore presentation of a visit with the late Gene Cernan, last astronaut to walk on the moon.

The answer will be revealed next week.
Question from the week before:
Approximately how many squished-up Earths would fit inside Saturn?
You could squish about 764 Earths into a hollowed-out Saturn. Ah, but how many Earth mass black holes? Answer is in the show.
