The Habitability of Exomoons Around Giant Planets
Quick fact
Some scientists think that exomoons could outnumber exoplanets in the habitable zone of a star, and that our own Moon—which stabilizes Earth’s tilt—might be a rare type that enhances habitability.
Why this is interesting
You know moons like Jupiter's Europa and Saturn's Titan are considered some of the most promising places to find life in our solar system. But what about moons orbiting giant planets in other star systems? Could they be even better hosts for life than Earth?
