Scientists Investigate How Heat Rises Through Europa’s Ocean

by Rebecca Owen 10 January 20249 February 2024

A new study examines how heat may be transferred from the mantle, through the ocean, and into the icy crust of one of Jupiter’s moons—perhaps among the most promising places in our solar system to search for life.
