NASAs Kepler mission has discovered over 1,100 extrasolar planet candidates. Including, "68 Earth-sized, 288 super-Earth-sized, 662 Neptune-sized, and 165 Jupiter-sized planets". 54 are found in their star's habitable zone, with five of those considered "near-Earth sized" [more inside]

Astronomers have found the first exoplanet within the "habitable" band around a star, or within the distance band around a start that would allow for liquid water. The planet is roughly 3 times the size of the Earth and orbits red dwarf Gliese 581 every 36.6 days at a distance of about 13 million miles.

Amid news of new extrasolar planet discoveries, including a system with a possible 7 planets, Greg Laughlin and Sam Arbesman have released a paper that will be published next month in the open-access journal PLoS One. "A Scientometric Prediction of the Discovery of the First Potentially Habitable Planet with a Mass Similar to Earth" (pdf of full paper) boldly predicts that: "the first potentially habitable planet will be discovered, in this case, as early as May 2011, and likely by the end of 2013." NASA's Kepler mission is set to release data on hundreds of candidate planets early next year. The mission has discovered 7 so far. (Pre-vio-usly)

Scientists have discovered a planet composed of scorching hot ice. Originally thought to be a gas giant due to its mass, its actually only four times the size of Earth and most likely composed of exotic forms of ice, such as Ice VII and Ice X with s surface temperature of 300° C.
