10,000 galaxies in a few square inches - something to think about


This ultra deep field photo taken by the Hubble Space Telescope (click on photo for large view) shows a small area of our universe when it was only 800 million years old.

Look at all those galaxies! Our galaxy alone - the Milky Way - is home to around 100 billion stars, many millions of which are orbited by planets, many thousands of which will be capable of supporting life in one form or another. Some of the galaxies in this photo are much larger than our Milky Way. Who in their right mind could possibly believe that we are the only intelligent life in the universe?

To put it all in perspective, Stephen Hawking said that "primitive life is very common and intelligent life is fairly rare. Some would say it has yet to occur on earth."

I agree with him.
