Colloquium:- Taste of Saturn’s Rings and Enceladus’ Ocean Water
How old are Saturn’s rings? Could life exist elsewhere in the solar system? Thanks to the 13-year-exploration of the Cassini-Huygens mission at Saturn, we are a step closer to answer these fundamental questions. In this talk, the speaker will review the current understanding of Saturn’s ring system and the plausible connection to the origin and evolution of Saturn’s icy satellites. He will also discuss Enceladus, a 500-km-sized icy moon constantly emitting 200 kg of water vapor and ice grains from its south-polar fissures each second, and why it is considered a potentially habitable Ocean World in the solar system. The presentation will be summarized with highlights on the interactions between the ring-moon system and its host planet, connections to various astrophysical phenomena, and future solar system explorations.
