There’s Hope for Life on Europa, a Distant Moon
Beneath its frozen surface could be a salty ocean—and maybe a comfortable home for small life forms.
Cynthia Phillips was mesmerized when she saw the latest pictures of her favorite moon. Here at last was a fresh look at Europa, an icy satellite of Jupiter. The moon resembles a truffle drizzled haphazardly with strips of melted white chocolate, as if the universe had rushed to finish a baking-show challenge. The images gave us a new sense of Europa’s topography, its collection of ridges and troughs appearing more intricate than ever. The lighting was different this time, Phillips told me, and the shadows brought out dramatic shapes in the terrain.
The images were taken by a Jupiter-observing spacecraft as it swept past Europa last week, coming within just 222 miles (358 kilometers) of the frozen surface.
