3 more homes for life in the universe?

Is anybody out there?

For millennia, humans have gazed at the night sky, asking this question. That's why scientists and NASA are eagerly searching for "exoplanets" - that is, planets that orbit around stars other than our sun.

Last week NASA's Kepler satellite reported the discovery of three Earth-sized exoplanets within the so-called "habitable zone," defined as the neighborhood of a star where liquid water - essential for life as we know it - can exist.

    I agree with all the post here. We should help our own planet before worrying about the other ones. Go green.

    Being an astrophysicist I can assure you planets are gay. Especially ones that aren't earth. Earth rules !

      I agree. I always root for Earth at football games and such. Our planet is better than everyone else's.

        That's why we are number 1 intergalactically. We're #1! We're #1.
