• Our solar system hosts almost 900 known moons; more than 400 orbit the eight planets while the remaining orbit dwarf planets, asteroids, and Trans-Neptunian Objects (TNOs). • Of these, only a handful are targets for astrobiology and could potentially support life as we know it, including Jupiter’s moons Europa and Ganymede, and Saturn’s moons Titan and Enceladus. • While these moons orbit two of the largest planets in our solar system, what about moons orbiting giant exoplanets, also called exomoons? • But, to find life on exomoons, scientists need to find exomoons to begin with.
Article Summaries:
- Scientists suggest that exomoons-moons orbiting distant giant planets-might be detected by observing lunar eclipses. While our solar system contains nearly 900 moons, only a few, such as Europa, Ganymede, Titan, and Enceladus, are considered potential habitats for life. Detecting exomoons is a prerequisite for studying their habitability. By monitoring the light curves of exoplanets for subtle dimming events caused by a moon passing in front of or behind its host planet, astronomers hope to identify these bodies and assess their suitability for supporting life.
