This study has the potential to help scientists better understand the interior composition of Europa and whether it could support life as we know it.<\/p>\n<p>For the study, the researchers analyzed data obtained by NASA\u2019s Juno spacecraft in 2022 when the spacecraft came within 220 miles (360 kilometers) of Europa\u2019s surface. The goal of the study was to put constraints on the thickness of Europa\u2019s ice shell, with the researchers noting current estimates range from 1.86 miles (3 kilometers) to more than 18.6 miles (30 kilometers). Since Europa is a prime target for the search for life beyond Earth, scientists hypothesize that cracks exist within the ice shell, enabling the delivery of nutrients from the surface to the subsurface liquid water ocean. In the end, the researchers estimated the average thickness of Europa\u2019s ice shell is approximately 18 miles (29 kilometers).<\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u201cThe 18-mile estimate relates to the cold, rigid, conductive outer layer of a pure water ice shell,\u201d said Dr. Steve Levin.
