When it descends through the thick golden haze on Saturn's moon Titan, NASA's Dragonfly rotorcraft will find eerily familiar terrain. Dunes wrap around Titan's equator. Clouds drift across its skies. Rain drizzles. Rivers flow, forming canyons, lakes and seas. But not everything is as familiar as it seems.

Last year, a study led by planetary scientist Richard Cartwright at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, proposed that deposits of carbon dioxide ice and other carbon-bearing molecules on Uranus's moon Ariel likely originated from chemical processes inside the moon—possibly even from a subsurface ocean.

Uranus moon Miranda may hold a hidden ocean below its surfaceby Jeremy Rehm for APL NewsLaurel MD (SPX) Oct 31, 2024 A recent study indicates that Uranus' small moon Miranda may contain a subsurface ocean, challenging prior assumptions about the moon's formation and characteristics and positioning it among a select few worlds in our solar system with potential habitats for life.

A new study suggests Uranus' moon Miranda may harbor a water ocean beneath its surface, a finding that would challenge many assumptions about the moon's history and composition and could put it in the company of the few select worlds in our solar system with potentially life-sustaining environments.

The surface of Uranus’ moon Ariel is coated with a significant amount of carbon dioxide ice, especially on its “trailing hemisphere” that always faces away from the moon’s direction of orbital motion. This fact presents a surprise because even at the frigid reaches of the Uranian system — 20 times farther from the Sun than Earth — carbon dioxide readily turns to gas and is lost to space. Scientists have theorized that something is supplying carbon dioxide to Ariel’s surface.
