The Voayger 1 in "purgatory cosmic” before entering the Milky Way

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.

It ‘about to become the first artificial 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.”

The researcher said Rob Decker: “We are using the flow of charged particles of the Voyager 1 sort of like a windsock to estimate the speed of the solar wind. We found that the solar wind speed is very low in this region and the type of irregular wind. First, The wind also blows towards us. We obviously travel in a whole new field. Scientists had previously suggested that there may be a layer of stagnant, but we were not sure existed until now. “

 Voyager 1 and 2 "Wear" a record turntable with a copper. The disc contains over 100 photographs of the earth, greetings from a selection of languages around the world and a variety of sounds from Earth.

The Voyagers have enough power and fuel to operate until at least 2020.

It is expected then that Voyager 1 sarà a 12,4 billion miles from the Sun, Mentre Voyager 2 swill be10,5 billion miles away.
