"We pointed the most powerful telescope ever built by human beings at absolutely nothing, for no other reason than because we were curious, and discovered that we occupy a very tiny place in the heavens." 1996: over 3000 galaxies are discovered; 2004: over ten thousand galaxies racing away from us in an ever-expanding universe! 47 billion light years away from us! Now we think there are more than 100 billion galaxies in the universe!
