Summary

Story summary

Washington State University researchers propose crustal delamination as a mechanism to deliver nutrients to Europa's subsurface ocean.
Salt-enriched ice on Europa may sink through its ice shell, transporting nutrients to the subsurface ocean.
The process, driven by denser ice formed by Jupiter's radiation and gravity, could occur in as little as 30,000 years.
NASA's Europa Clipper mission will explore the findings and is set to arrive in 2030.
