Scientists celebrated Sunday after finding more than 700 suspected new planets — including up to 140 similar in size to Earth — in just six weeks of using a powerful new space observatory.

Early results from NASAâ€™s Kepler Mission, a small satellite observing deep space, suggested planets like Earth were far more common than previously thought.
Past discoveries suggested most planets outside our solar system were gas giants such as Jupiter and Saturn — but the new evidence tipped the balance in favor of solid worlds.
Astronomers said the discovery meant the chances of eventually finding truly Earth-like planets capable of sustaining life rose sharply.
