James Green, a
NASA scientist, explains us that as a planetary scientist that the question: -Is
there life beyond Earth in our solar system? - they don’t take very seriously until
this notice. He says that the components for life are liquid water, energy and
organic material but also have it for a long time for grow and evolve.
James didn’t believe
that life could exist life beyond earth, for example planets that are next to
the sun there’s to hot and warm and planets that are passing the earth there’s
cold and the water is frozen. But investigating they found four exceptions,
Mars, Titan, Europa and Enceladus. In Mars, there is water that flows in to the
craters in summer, Enceladus create an ocean, and they found particles that
prove that could be complex life in this moon and the same pass in Europa. This
too moons are not the traditional place to live but they have liquid water and, if
they’re organics, life could exist in this planets.
The other
moon, Titan, is a Saturn’s moon. This moon have an atmosphere with nitrogen
that the radar Cassini found, and also found liquid, but it’s not water it’s
another type of liquid, methane that could replace water.
Finally this
incredible scientist says that in approximately ten years the question will be solved,
and if the answer is yes, the life will be in all the solar system.
