NASA kepler Space Telescope has found two new Earth-sized Alien Planets

December 5, 2011: NASA’s Kepler mission has confirmed its first planet ( Kepler-22b ) in the “habitable zone,” the region where liquid water could exist on a planet’s surface

The newly confirmed planet, Kepler-22b, is the smallest yet found to orbit in the middle of the habitable zone of a star similar to our sun. The planet is about 2.4 times the radius of Earth. Scientists don’t yet know if Kepler-22b has a predominantly rocky, gaseous or liquid composition, but its discovery is a step closer to finding Earth-like planets.

December 20, 2011: NASA in telephonic conference just announced, Kepler space telescope has found two new Earth-sized planets orbiting a distant sun-like star, and the researchers who made the find say these two are the size of Earth or smaller.

The planets, called Kepler-20e and Kepler-20f, are too close to their star to be in the so-called habitable zone where liquid water could exist on a planet’s surface, but they are the smallest exoplanets ever confirmed around a star like our sun.

Kepler-20e is slightly smaller than Venus, measuring 0.87 times the radius of Earth. Kepler-20f is a bit larger than Earth, measuring 1.03 times its radius. Both planets reside in a five-planet system called Kepler-20, approximately 1,000 light-years away in the constellation Lyra.

Kepler-20e orbits its parent star every 6.1 days and Kepler-20f every 19.6 days. These short orbital periods mean very hot, inhospitable worlds. Kepler-20f, at 800 degrees Fahrenheit, is similar to an average day on the planet Mercury. The surface temperature of Kepler-20e, at more than 1,400 degrees Fahrenheit, would melt glass.

  1. Quite co-incidental that NASA happens to stumble upon two more “earth-like” planets just before 2012 arrives..
    Forgive my accusation but its almost as if they will be exposed this year as having been in contact with various ET’s for many years gone by….and will want to make it seems as if their relationship with intelligent life is “very recent”…and “just discovered”.
    All humans will point fingers and be very resentful towards NASA when (I hope) that positive ET’s visit us in 2012.
    NASA/Illuminati’s secrte relationship with ET’s is soon to be exposed…

  2. It is very dissappointing when you realise that the authorities and powers that be, have taken it upon themselves to decide what is good for you and me , what we are and are not to be informed about. It is not healthy to live in denial or to keep secrets like NASA has..We need each other.

  3. wonder if nasa will get a crew togeather an take a space flight mission to one of the new earths to check if they r really liveable lol if so they could set up a few green houses there an see if our blank life from our earth is able to grow on it plus .if we cant start over we can better our tec. an not palute the atmosphere . just think bout it insteat of using gases an fuels for flight just dezign a new engine that can run off a plutonium fuel cells an dezign booster rockets for speed an transports .just think lol we could start a furture like the movie star trek just think bout how cool that would be. well lol ttyl.
