Researchers linked to Washington State University proposed in 2026 that salty, oxidant-rich ice on Europa’s surface could become dense and weak enough to detach and slowly sink through the moon’s ice shell — potentially carrying life-supporting chemistry down to the hidden ocean in as little as 30,000 years under the most favorable model conditions.

A 2026 Europa model proposes that salty, weakened surface ice could founder through the shell, offering a possible path for oxidant chemistry to reach the ocean.
