Europa
4 reportsA source-based view of Europa considers atmosphere or exosphere and water or ice evidence, with separate attention to spacecraft observations. The account follows model comparison as the direct record and multiwavelength observations as the broader comparison for spacecraft observations; confidence is limited by the fact that limited viewing geometry and indirect measurements can leave competing explanations.
