Earth has a few more near-twin planets outside our solar system, tantalizing possibilities in the search for extraterrestrial life. Astronomers announced Tuesday that depending on definitions, they have confirmed three or four more planets that are about the same size as Earth and are in the not-too-hot, not-too-cold "Goldilocks Zone" for liquid water to form. They get about the same heat from their star as we get from the sun. That brings the total number of planets that are no bigger than twice Earth's size and in the habitable temperature zone to eight or nine. http://apne.ws/1wl5naF http://bit.ly/1fJ5yqZ
