Europa is covered with ice that is riddled with cracks. It surface temperature can get as low as -328 degrees Fahrenheit, not exactly warm enough to support life. But under the ice is an ocean that scientists believe is warmed internally. It could support life, if the water's chemistry is right. Astronomers want to send an unmanned craft to try to find out.
