Little gray men with oversized heads, long arms and flying saucers... This is the image that many people have had of extraterrestrials for over a hundred years, and the Roswell affair accentuated this belief!

But today, we're not going to try to find out what they look like, but rather whether they can exist, and if so, on what planet?

Are extraterrestrials from Mars?
Have they ever come to meet us?
Are there habitable planets close to our own?

Today, we look up to see if we're alone in the universe!
