The launch is scheduled for March 5 and is supposed to be a more sophisticated listening for extra solar planets the size of Earth!

What could be the possibilities of life then?

Me, me!

The whole question of intelligent life elsewhere in the universe boils down to two questions:

1. As it is difficult for life to come to the existence of non-life.
2. How unique is the Earth's environment and history of the environment in the universe and how necessary was that the history of the environment for the development of intelligent life (the man).

The first question asks whether, given the right environment, is it likely that life would start anywhere? We believe that the answer to this question is: Very likely. The reason is that the more we look around the world more precursors to life, we find ourselves. The more we look around the Earth, the more we see that life on Earth happened very shortly after the Earth was created (geologically speaking). The question of life elsewhere in our solar system is probably the most important question that all of our space exploration seeks to answer. We found no slam-dunk evidence of life elsewhere, but we continue to find places where he could grow and we continue to look.

The second question concerns the feeding of primitive life in complex organizations. On Earth (our only example of life we have now) it took more than 3.5 billion years to reach the man, three and a half billion years when the environment on Earth has been relatively stable. For about 3 billion years of life has been mostly unicellular. During this immense period of the environment on Earth has been supported further development of life, even in the face of a radically changing environment solar. Is it likely that this planet could exist elsewhere in the universe? The number of stars are huge, so it might seem a near certainty that there are "planets like Earth elsewhere in the universe. Consider this: the Earth has developed life and as far as we now know Mars and Venus do not. They are planets similar to Earth - planets very similar to Earth. The answer must be more complicated than just "planets like Earth."

Another thing to consider: our sun, Sol, has over the last 4 billion years has increased its production by about 25% due to normal stellar evolution. It is a huge change in production and without a compensating factor of the Earth during this period would have been a scoop of ice as a barren planet Venus. He didn't, but we do not know what the factor was maintained as a constant environment.

Now consider the probability of receiving foreign visits Earth. The chances of alien life forms came to visit us three additional questions. One addresses the problem of space and the temporal problem. The third addresses the real possibilities Travel.

1.Si life form to develop advanced technologies not elsewhere in the universe is it likely they would be contemporary with the man when he is technologically sophisticated.
2.Is it is likely that some form of life could develop a technology sophisticated enough about us, so that they could not reasonably be visiting Earth?
3.Do there really is a physical "new" that would travel vast distances in reasonable times?

When alien extraterrestrial life is considered what we are usually covered: the technologically sophisticated life. We do not often talk about bacteria or worms or even Homo Erectus visiting Earth. Humans have been technologically advanced for only about 100 years with radio communications and rockets. Our relevance.
