Bizarre features on Europa’s icy surface suggest a warm interior. This view of the surface of Jupiter’s moon Europa was obtained by NASA’s Galileo mission, and shows a color image set within a larger mosaic of low-resolution monochrome images. Galileo was able to survey only a small fraction of Europa’s surface in color at high resolution; a future mission would include a high-resolution imaging capability to capture a much larger part of the moon’s surface.
