On the Back
Beneath the icy surface of Jupiter’s moon Europa is perhaps the most promising place to look for present-day environments suitable for life.
Slightly smaller than Earth's Moon, Europa’s water-ice surface is crisscrossed by long, linear fractures. Like our planet, Europa is thought to have an iron core, a rocky mantle and an ocean of salty water. Unlike Earth, however, Europa’s ocean lies below a shell of ice probably 10 to 15 miles (15 to 25 kilometers) thick and has an estimated depth of 40 to 100 miles (60 to 150 kilometers).
