To find out, a space probe could send a "cryobot", a heated ice drill, down to Europa's surface. This would then tunnel through the ice by melting it. Once it reaches the water thought to lie beneath the ice, it would start to transmit pictures and information back to Earth.Extraterrestrial life, or ET, is any life that does not originate from Earth. None has so far been discovered. Alien or extraterrestrial life includes anything from simple bacteria to intelligent, complex life-forms—perhaps even more advanced than us humans. The search for other worlds where life could exist covers our neighbouring planet Mars, more distant moons such as Enceladus, Europa or Titan, and planets in other solar systems many light years away.

There are many vents like this one (pictured) in the Earth's oceans. The water is rich in dissolved minerals. Bacteria use these minerals to make food. Could bacteria be found living in warm-water oceans beneath the crusts of moons in the Solar System, such as Europa or Enceladus?

Conditions for life

On 15th August 1977, a radio signal lasting 72 seconds was detected by a radio telescope used in the search for extraterrestrial intelligent life. A scientist wrote “Wow!” next to the signal on the computer printout, so that became its name. Despite repeated efforts to find out where the signal came from, it has not been detected since.
