New Scientist is carrying this article detailing the first discovery of a more earth-like planet orbiting another sun. Found circling mu Arae, a star about 50 light years from ours, the planet is still several times more massive than ours, orbits its sun in just 9.5 days, at a distance of less than 1/10th of the Earth-Sun combination. However, the scientists who discovered it think it's likely to be a rocky world instead of another gas giant. The technique holds promise to find even smaller worlds, but probably not as small as Earth.
