The moon's icy crust is made of water, which is a necessary ingredient for life. While the surface of the moon is far too cold for life to exist, scientists believe that there is a layer of liquid water beneath the frozen surface. Deep inside most planets - and some moons - is energy that generates heat. This could be happening on Europa, which would melt the ice closer to the inside of the planet. And where there's water and heat, there could possibly be life.
Because of this possibility, some scientists would like to send some equipment to Europa to prove, or disprove, this theory. This equipment would have to break through the surface to reach the liquid lake or ocean below. Once there, it could release a smaller object capable of travelling through water and collecting data. The cost of building and sending equipment like this through hundreds of millions of kilometres of space would be extremely high. Other, less costly space missions are being carried out first.
To explore how scientists think life could exist there - in a place not just cold, but extremely dark - they look at the Earth's oceans. Deep below the surface, there are life forms that survive independently from sunlight, a fact scientist once thought was impossible. At the bottom of the sea, there are volcano-like openings that produce heat. Near these openings live giant worms. clams and other types of sea life. They eat tiny bacteria that live off elements produced by the openings. It's almost like an independent world down there, and almost completely dark. If something like this can exist on Earth, perhaps it could exist on Europa.
A - It is now certain that there is a source of heat deep inside Europa.
1) True 2) False 3) Not stated
B - Scientists want to do research under Europa's surface
1) True 2) False 3) Not stated
C - A trip to Europa would cost less than other planned missions.
1) True 2) False 3) Not stated
D - Scientists used to believe that light was necessary for life to exist.
1) True 2) False 3) Not stated
E - Although they can't see, the giant worms still have eyes.
1) True 2) False 3) Not stated
