EARTH'S TWIN FOUND AT HEART OF MILKY WAY (News in Science, 26/1/06)

Astronomers have discovered the most Earth-like planet so far, close to the
centre of our galaxy.

And why do we want to keep finding copies of ourselves? Don't we want to find worlds and beings who are really different from each other? Reminds me of the TV ad where a group of Americans are in Europe on a bus tour and they only get excited when they see a McDonald's or similar familiar "landmarks".

Yeah, yeah, I know - we know that Earth has life so we're looking for what we know, but with a whole big Universe to explore, let's not stick with the McDonald's forever.
