    Default The layman's guide to the size of the Universe

    For those who have a passing interest in astronomy this short video puts our place in the grand scheme of things astronomical in perspective.

    When you look up at the night sky it's fascinating to remember that you're a time traveller, as well as a paid-up citizen of that great expanse of time, space and mystery that is, in every sense, your home.

    Just goes to show that there must be other life out there.

    I'm also interested on the odds of us individually existing at all when you take in all the butterfly effects down through the generations.

    There's more different positions in a game of chess than there are atoms in the known universe.

    The chances of this little speck in space being the only inhabited world are insignificant. The Universe is, in all likelihood, teeming with life.

    We're hoping to find evidence of some kind of primitive lifeform, even extinct ones, on Mars via the Mars Rover. Imagine the repercussions if we do.

    The moons of Jupiter probably are the only candidates in our lifetime for live life, particularly in the seas of Europa....

    Considering we still haven't found Shergar, I don't fancy our chances

    Hmmm. Jupiter is a strange planet. Dozens of moons, but Europa, as you rightly point out is the one with the most life-potential.


    Europa, closer to Jupiter than Ganymede, is the smoothest natural body in the solar system. It resembles a billiard ball until seen very close-up. At that distance you can start to see dark, deep, and narrow cracks. In scale, though, the relief is no bigger than a line on a billiard ball made with a felt-tipped marker. Geologists think that Europa has liquid water underneath the icy surface - and possibly life.
