A new ground-based radar study aims to improve understanding of Jupiter’s moon Europa, focusing on what lies beneath its icy surface. Europa is of major interest to astrobiologists because it is believed to contain a large subsurface ocean of liquid water. Estimates cited across the reports suggest that the ocean could hold roughly twice as much water as all of Earth’s oceans combined, which would make Europa one of the most water-rich places beyond Earth. The studies frame this subsurface ocean as a key factor in determining whether Europa could potentially support life, either in forms already known or in ways scientists have not yet identified. The radar work is presented as a way to investigate the properties and structure of Europa’s ice shell, contributing to scientists’ broader effort to understand how the moon’s interior works and how the ocean may be connected to its surface. While the sources emphasize Europa’s habitability potential, they consistently center the radar-based investigation as a step toward characterizing the ice and ocean system that could make the moon relevant to the search for extraterrestrial life.
