- "Europa is the most exciting place for the study of life."

Europa is a moon of Jupiter that, according to recent photos taken by the Galileo probe, has liquid water oceans underneath the frozen ice that makes up its surface. The oceans are roughly the same area that Earth's oceans are, and the oceans are 60 miles deep, which may be large enough for submarine volcanoes. Because of the abundant oceans on the moon, this may mean that it supports life. However, we'll have to wait for a probe to drill through the ice and see.
