New planet discovered: Kepler-22b earth like planet 600 light year away

Some 600 light years away, NASA scientists have discovered a planet that seems very similar to planet earth. The scientists are so enthusiastic with the new discovery that they have called it a twin of our own earth as they think the new planet has what it takes to sustain a human life.
NASA scientists have said that the new planet that is much bigger in size than our own earth may be ideally suited for plants to grow and sustaining animal life. The possibility of vegetation and life there has filled scientists with a newfound enthusiasm.
Scientists have named the new planet as Kepler 22 and have suggested that it is complete with a similar solar system that is very close to our own and say that never in history of space exploration, they have stumbled upon such a planet that had so much resemblance to earth and that could sustain life, the way our earth does.
America’s space agency NASA while explaining its very objective Kepler Mission says on its portal, “Considering that we want to find planets in the habitable zone of stars like the Sun, the time between transits is about one year. To reliably detect a sequence one needs four transits. Hence, the mission duration needs to be at least three and one half years. If the Kepler Mission continues for longer, it will be able to detect smaller, and more distant planets as well as a larger number of true Earth analogs”.
NASA scientists have stumbled upon an area on the newly discovered planet that is not too hot and not too cold either ideally suited for vegetation and human life. They say that this area keeps the water on normal temperature and there water neither freezes nor boils.
Regarding the Kepler Mission NASA website further says, “The Kepler instrument is a specially designed 0.95-meter diameter telescope called a photometer or light meter. It has a very large field of view for an astronomical telescope 105 square degrees, which is comparable to the area of your hand held at arm’s length. The fields of view of most telescopes are less than one square degree. Kepler needs the large field of view in order to observe the large number of stars. It stares at the same star field for the entire mission and continuously and simultaneously monitors the brightnesses of more than 100,000 stars for at least 3.5 years, the initial length of the mission, which can be extended”.
