Galaxy has 'billions of Earths'

There are 8 times more dollars in the Stimulus bill than possible Earths in the galaxy.

From the BBC:

There could be one hundred billion Earth-like planets in our galaxy, a US conference has heard.

Dr Alan Boss of the Carnegie Institution of Science said many of these worlds could be inhabited by simple lifeforms.

He was speaking at the annual meeting of the American Association for the Advancement of Science in Chicago.

So far, telescopes have been able to detect just over 300 planets outside our Solar System.

We'll make great pets.
