NASA has announced that Voyager 1 space probe, launched into space in 1977, has left the solar system becoming the first man-made object that enters interstellar space.
conclusion reached after knowing the new data from the spacecraft , which have been the subject of research published in the journal Science .
According to these data, published by the magazine and confirmed by NASA to probe l left the solar system for more than one year , in August 2012, and has explained Ed Stone, responsible mission scientist at the California Institute of Technology.
“ believe that humanity has taken a historic step entering interstellar space (between the Sun and another star belonging to),” said Stone.
New
analysis of plasma density around the ship were found to be consistent with standard densities of interstellar region, according to researchers at the University of Iowa, among which is located Don Gurnett, who published their study in the American magazine site Science .
Voyager-1, which is over 18,000 million kilometers from the Sun , left the border area with another system, denonimada heliopause, to the August 25, 2012.
The surprise came when they saw the oscillations in the data showed that the probe was in a totally new, “consistent with what would be expected in outer space and totally different from the heliosphere, the bubble that forms the light Solar, “said Don Gurnett. “We have clearly crossed the heliopause, the border region between the solar plasma and the interstellar plasma,” he added.
This historic moment has generated controversy in recent months. Two studies published earlier this year, the last in August on the basis of other data, had already concluded that the probe was outside the solar system last year, but NASA had considered that these studies were not conclusive.
