Answer: Saturn
Notes: In November 2022 and July 2023, the National Aeronautics and Space Administration (NASA) observed Titan, Saturn’s largest moon, using the James Webb Space Telescope (JWST) and the Keck Observatory. Titan is the second-largest moon in the solar system and the only one with a thick atmosphere and surface lakes of methane and ethane. It has Earth-like weather patterns, including clouds, rainfall, and changing seasons. Scientists detected clouds in Titan’s mid- and high northern latitudes that rose over time, showing convection-driven weather. This is the first confirmed evidence of such cloud activity near Titan’s northern seas like Kraken Mare and Ligeia Mare. The findings deepen our understanding of Titan’s methane cycle, which works like Earth’s water cycle, and offer clues about prebiotic chemistry on icy moons.
