The spacecraft is close to leave the Solar System and to enter the uncharted territory of the Milky Way after more than three decades in space.
Voyager 1 was launched with her twin, the Voyager 2, dalla US National Aeronautics and Space Administration (NASA) in 1977.
Voyager 1 traveling at less than 11 kilometers per second and the transfer of information comes from almost 11 billion miles away from the sun.
E 'on the verge of becoming the first man-made object to leave the Solar System , even though NASA says it will take several months and years before it enters completely into the interstellar.
Ed Stone, Voyager project scientist at the California Institute of Technology in Pasadena, said: “Voyager tells us now that it is in a region of stagnation in the outermost layer of the bubble around our solar system, showing that it is out of “We should not wait long to find out how the space between the stars it really is.”
French astronomers have confirmed the existence of the first rocky exoplanet able to meet the fundamental requirements for life. This does not mean that astronomers really know if there is life there, but simply that there are conditions.
These planets have the right distance from their star to support water, in addition to a suitable temperature and atmosphere to sustain life. “We are confident that the planet is in the habitable zone, and, has a surface, This should have a pleasant temperature,” told reporters Bill Borucki, Kepler principal investigator at NASA's Ames Research Center.
A 600 light years away, Kepler-22b is 2,4 times the size of the Earth (a super-Terra), and orbits its sun-like star each 290 days.
The average temperature at the surface is assumed to be approximately 22 degrees Celsius. The planet was one of the first to have been captured by NASA after launch Kepler in March 2009.
NASA also announced that Kepler discovered 1.094 potential planets, twice the number that had previously been estimated. Kepler is NASA's first mission seeking Earth-like planets orbiting just like our, and has cost NASA about 600 million dollars.
