It is not yet known if there is life on other planets or moon systems, yet alone intelligent life. I feel that finding life elsewhere is a challenge for present day Astronomers even after all of the technological advances. This battle comes from the sheer size of the universe. Within our own galaxy there are more than 10 billion stars, and it is 100,000 light years in diameter. Thus, it would take a long time to reach stars in our galaxy let alone other galaxies. Also when astronomers use telescopes to see these stars we are not seeing them as they are presently but we are looking into the past of that star. If a star is 100,000 light years away when we see it we see it 100,000 years earlier. This means there could be life on the planets that orbit this star presently but we will only see it when enough time has passed. I believe that there is life somewhere in the universe we may just never be able to prove it.
