Clouds on Titan

For the first time, NASA’s James Webb Telescope captured active methane cloud formation in Titan’s northern hemisphere — showing real-time weather on Saturn’s largest moon.

Earth-Like Weather

Titan is the only place beyond Earth with a weather system that includes clouds, rainfall, and liquid lakes — but with methane, not water.

Northern Hemisphere Surprise

Methane clouds were seen forming at different altitudes over Titan’s northern lakes, completing the picture of its dynamic weather cycle previously seen only in the south.

Unseen Chemistry Unveiled

JWST detected elusive methyl radicals in Titan’s atmosphere — a key piece of its organic chemistry puzzle, never observed before.

Breaking Down Methane

Methyl radicals form when sunlight and Saturn’s magnetosphere break apart Titan’s methane — kickstarting complex chemical reactions that build its lakes and atmosphere.

Titan’s “Chemical Cake”

Scientists describe it as watching a “chemical cake rising in the oven” — seeing real-time organic reactions, not just their end products.

Dragonfly Is Coming

NASA’s Dragonfly mission will send a flying drone to Titan in 2034, to explore its surface, weather, and hunt for signs of life and prebiotic chemistry.

JWST’s Crucial Role

These JWST discoveries are setting the scientific agenda for Dragonfly, giving insights into where to look and what to study on Titan.

Titan’s Habitability Question

With its thick atmosphere, methane rains, and complex chemistry, Titan remains one of the most Earth-like — and intriguing — places in the solar system for potential life.
