NASA finds planet that's just about right for life
NASA has found a new planet outside Earth's solar system that is eerily similar to Earth in important aspects.
Scientists say the temperature on the surface of the planet is about a comfy 72 degrees (22 Celsius). Its star could almost be a twin of Earth's sun. It probably has water and land. It was found in the middle of the habitable zone, making it the best potential target for life. (AP)
