Fantastic images. I will be showing them to my kids tomorrow.
On the question of intelligent life out there, the science is clear that it is probable that life arose frequently throughout the universe. But evolution is a complex process, with many end points. A species can become dominant in its own niche without developing intelligence. Look at sharks which have not changed in 200 million years, because they are perfect for their environment.
The universe probably abounds in life, but we know as a matter of certainty that there is no technological civilisations near us. If any civilisation was using radio signals we would be picking them up on our radio telescopes. We would not necessarily be able to interpret them, but we could identify them as coming from an intelligent souce as opposed to a natural source.
The tragedy is that if there are intelligent beings out there (and the chances are that there are) the distances between us and them preclude any contact. What a shame.
