Scientists looking at a star 150 light-years away with the Hubble Space Telescope found that a planet there contains sodium in its atmosphere. This demonstrates that it may be possible to search for the chemical signature of life on planets beyond the solar system.

?Suddenly, discussing searches for Earth-like planets seems quite reasonable,? says David Charbonneau, an astronomer at the California Institute of Technology. ?This opens up an exciting new phase of extrasolar planet exploration, where we can begin to compare and contrast the atmospheres of planets around other stars.?
