An Ocean We Have Never Seen
Galileo’s magnetic readings support a conducting layer beneath Europa’s ice; the pictured under-ice world is an imagined scene.

THE OBSERVATION
What we can actually see.
Galileo measured a magnetic response near Europa that is consistent with currents induced in a conductive layer as Jupiter’s magnetic environment changes. A global salty ocean beneath the ice is the leading interpretation. Spacecraft have mapped Europa’s exterior, but no camera has entered the ocean or photographed its seafloor. Whether water and rock exchange enough energy-bearing material for life is a separate question.
THE ILLUSTRATION
What the artwork imagines.
The image invites a view under the ice that no spacecraft has had. Its light, colors, water, and any impression of depth or seafloor detail are illustrative choices. It cannot show the ocean’s chemistry, living organisms, or the present activity of the rocky floor.
FROM THE ILLUSTRATED ARTICLE
The story that inspired it.
The companion article asks whether an inferred ocean can be habitable if its seafloor is quieter than familiar Earth analogies suggest. The picture gives that hidden setting a visual form while the story keeps the ocean evidence and habitability question distinct.
