Lecture no. 12 from the course: A Field Guide to the Planets
Taught by Professor Sabine Stanley | 32 min | Categories: The Great Courses Plus Online Science Course
Today we know of 79 Jovian moons—the spherical Io, Europa, Ganymede, and Callisto, and dozens of other smaller, odd-shaped satellites. Learn why Jupiter’s gravitational forces plus the orbital resonance of the three interior moons make these some of the most promising places to search for extraterrestrial life—and why scientists believe the Jovian system once included generations of other moons, now gone.
