Another Earth Just 12 Light-Years Away?
Ken Croswell, Science Now
Astronomers have discovered what may be five planets orbiting Tau Ceti, the closest single star beyond our solar system whose temperature and luminosity nearly match the sun's. If the planets are there, one of them is about the right distance from the star to sport mild temperatures, oceans of liquid water, and even life. Don't pack your bags just yet, though: The discovery still needs to be confirmed.
