Active Weather Region Spotted for First Time on a Faraway Moon
- Astronomers spotted active weather patterns with cloud convection in Titan's northern hemisphere during summer using JWST and Keck telescopes in 2023.
- The discovery follows earlier evidence of southern hemisphere weather and addresses gaps in understanding Titan's climate and methane cycle.
- Titan has a dense nitrogen atmosphere, methane clouds that evolve like Earth's convective cells, lakes in the north fed by methane rain, and a troposphere about 27 miles high.
- Lead author Conor Nixon explained that observations of methane clouds near Titan’s north pole demonstrate how rainfall contributes to replenishing methane that has evaporated from the moon’s lakes.
- NASA plans the Dragonfly mission to launch in 2028 and arrive by 2034 to study Titan's habitability and chemical processes, while methane depletion threatens Titan's atmosphere long-term.

Astronomers spot rising methane clouds on Saturn’s moon Titan
For the first time, astronomers have observed cloud convection in the northern hemisphere of Titan, Saturn’s largest moon. This groundbreaking discovery was made using the W. M. Keck Observatory in Hawaiʻi, offering new insights into the mysterious weather patterns of this distant world. Titan is unique in our solar system because it has weather patterns […] The post Astronomers spot rising methane clouds on Saturn’s moon Titan appeared first on…
