    NASA's planet-hunting Kepler spacecraft has confirmed the discovery of its first alien world in its host star's habitable zone - that just-right range of distances that could allow liquid water to exist - and found more than 1,000 new explanet candidates, researchers announced today (Dec. 5).

    The new finds bring the Kepler space telescope's total haul to 2,326 potential planets in its first 16 months of operation.These discoveries, if confirmed, would quadruple the current tally of worlds known to exist beyond our solar system, which recently topped 700.

    The potentially habitable alien world, a first for Kepler, orbits a star very much like our own sun. The discovery brings scientists one step closer to finding a planet like our own - one which could conceivably harbor life, scientists said.

    "We're getting closer and closer to discovering the so-called 'Goldilocks planet,'" Pete Worden, director of NASA's Ames Research Center in Moffett Field, Calif., said during a press conference today. [Gallery: The Strangest Alien Planets]

    The newfound planet in the habitable zone is called Kepler-22b. It is located about 600 light-years away, orbiting a sun-like star.
    Kepler-22b's radius is 2.4 times that of Earth, and the two planets have roughly similar temperatures. If the greenhouse effect operates there similarly to how it does on Earth, the average surface temperature on Kepler-22b would be 72 degrees Fahrenheit (22 degrees Celsius).

    Hunting down alien planets

    The $600 million Kepler observatory launched in March 2009 to hunt for Earth-size alien planets in the habitable zone of their parent stars, where liquid water, and perhaps even life, might be able to exist.

    Kepler detects alien planets using what's called the "transit method." It searches for tiny, telltale dips in a star's brightness caused when a planet transits - or crosses in front of - the star from Earth's perspective, blocking a fraction of the star's light.

    The finds graduate from "candidates" to full-fledged planets after follow-up observations confirm that they're not false alarms. This process, which is usually done with large, ground-based telescopes, can take about a year.

    The Kepler team released data from its first 13 months of operation back in February, announcing that the instrument had detected 1,235 planet candidates, including 54 in the habitable zone and 68 that are roughly Earth-size.

    Of the total 2,326 candidate planets that Kepler has found to date, 207 are approximately Earth-size. More of them, 680, are a bit larger than our planet, falling into the "super-Earth" category. The total number of candidate planets in the habitable zones of their stars is now 48.

    To date, just over two dozen of these potential exoplanets have been confirmed, but Kepler scientists have estimated that at least 80 percent of the instrument's discoveries should end up being the real deal.

    At the speed of light,it would take mankind 600 year to reach this planet,sometimes i wonder why bother themselves

    with faster than light neutrino pulses our coded messages would arrive much sooner! Out and Over.

    coded messages aint gonna solve earth,s overpopulation woes,we need somewhere to inhabit-how we are to get there is the question

    if you set out for the planet in spacecraft travelling at 99.9% the speed of light,due to time dilation (slowing down of time on spacecraft) the entire duration of journey would be 30 years while 600.6 years would have elapsed on earth. Duration for two way journey will be 60 years while earth would have aged by 1333 years.

    we need another planet for what you scientists? it is better if you use those money used for exploration to improve Earth,s Population life. Do you want to reach Creator of the world?

    I am, in advance, booking a place in the new discovered world should NASA succeed with their plans. Perhaps my migration to there will bring me new life hopes as my life on the planet earth has proved nothing but a series of miseries and upheavals.

    there is no over population in this world. world still have more space to accomodate those living things, resources are still there etc. etc.the only thing here is unequal distribution of the existing resources which lead other to be better off while other worse of. we dont need more space anyway.
    may be developed countries want to leave developing countries in vein. take those resources where we cannt even see them and enjoy even a bit.

    Theory, theory, theory,.....hakuna object material inayosafiri hata kwa nusu ya speed ya light leo hii. Labda hizi discoveries zitawasaidia vizazi vijavyo,kama discoveries za wanasayansi wa zamani zinavyotusaidia leo.
