What is Enceladus?

Enceladus is one of Saturn’s most fascinating moons because Cassini detected geyser-like plumes erupting from fractures near its south pole. These plumes contain water vapor, ice particles, salts, and organic compounds, suggesting a subsurface ocean beneath the ice. The moon’s bright surface reflects sunlight strongly, making it one of the most reflective objects in the Solar System. Its activity has made it a major target in the search for habitable environments.
