NEW YORK - Scientists have found two Earth-sized planets orbiting a star outside the solar system, an encouraging sign for prospects of finding life elsewhere. The discovery shows that such planets exist and that they can be detected by the Kepler spacecraft, said Francois Fressin of the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass. They're the smallest planets found so far that orbit a star resembling our sun.

The announcement this week of NASA's Kepler mission's first confirmed planet in the so-called "habitable zone" - that just- right region around a star that would provide comfortable conditions for liquid water, and perhaps, life - has ignited a media frenzy devoted to the hunt for "Earth's twin. Scientists soberly remind us that it is not, in fact, Earth's twin, but an intriguing discovery that brings us closer to finding it.

WASHINGTON - A newly discovered planet is eerily similar to Earth and is sitting outside our solar system in what seems to be the ideal place for life, expect for one hitch. It's a bit too big. The planet is smack in the middle of what astronomers call the Goldilocks zone, that hard to find place that's not too hot, not too cold, where water, which is essential for life, doesn't freeze or boil. And it has a shopping mall-like surface temperature of near 72 degrees, scientists say.

Two of the country's most celebrated scientists met at Yale University Wednesday to accept honorary medals from the Peabody Museum and answer a question: What is the future of life on Earth? Edward O. Wilson, professor emeritus of zoology at Harvard University and one of the world's leading authorities on ants, sat on the stage at Sprague Hall with Peter H. Raven, world-renowned expert on rain forests, plant evolution and conservation. Raven also is a professor of botany at Washington University in Saint Louis, Mo.
