On February 2, 2011, NASA announced that its Kepler space telescope found its first Earth-size planet. In fact, it found five Earth-size planets all orbiting about one star, Kepler-11.

A study from the European Southern Observatory (ESO) has announced that there are about one hundred possibly habitable rocky planets about the size of Earth or larger within 30 light-years from our planet.
Looking for a place to get away from it all and start over? Thanks to NASA’s Kepler mission, they may have just found the perfect out of the way planet for you and it’s just down the street or so at only 500 light years away. Pack your swimming trunks, scientists think there’s water a-plenty and maybe even an inhabitant or two to keep you company. :D
How about a planet that acts like a comet! The Hubble Space Telescope has found planet HD 209458b. NASA says it is a gas giant that is so close to its star—about 4 million miles away—that its atmosphere is escaping into space so fast that the created winds look like a sweeping tail of a comet.
The Earth has a tail and this dusty feature has been mapped by the Spitzer Space Telescope. Such a mapping is helping astronomers find very distant planets around other stars than our Sun, what are called extrasolar planets.
The Kepler Space Telescope has observed a Jupiter-sized planet traveling across its parent star. And, it is only reflecting about 1% of the light that impinges on it — making it appear as the blackest, darkest exoplanet ever known.
