probe Voyager 1, the U.S. space agency (Nasa), became the first man-made object to enter interstellar space and leave the solar system, said on Thursday the agency.
Scientists explained that the unmanned spacecraft magnetic crossed the border between the Sun, the planets of the solar system and the solar wind from the rest of the galaxy.
The announcement was made over 36 years after the unmanned spacecraft begin the journey that gave humanity the first foreground image of Jupiter and Saturn before heading into deep space.
“On leaving the heliosphere and cosmic seas settle in among the stars, Voyager joined other historical events operating as the first circumnavigation of the Earth and the first steps on the moon,” said Ed Stone, chief scientist of the mission .
“We are in a new region of space where nothing ever been before,” he emphasized. According to NASA, Voyager 1 is currently 18.8 billion miles from Earth.
speculation that the probe was out of the solar system were repeated in recent years, but only today NASA has confirmed that the tests allow magnetic safely say that the ship overcame the barrier of reach sunlight.
In March, several scientists outside the agency presented data in the journal “Science” arguing that the probe had reached interstellar space on August 25 last year, but warned that Stone was still necessary to detect certain changes in the magnetic field to confirm the information.
heliosphere, the region in which transitioned to a year ago Voyager 1, is a huge mass of solar particles that surrounds the planet and protects the galactic radiation while now, abroad it is a dark and cold space between the stars.
twin spacecraft, Voyager 1 and Voyager 2, were launched in 1977 for a first mission. The aim of the first was to explore Jupiter and Saturn, and Voyager 2 traveled to Uranus and Neptune, before continuing its exploration of the limits of the influence of the sun.
The two ships continued issuing data scheduled until August 25 last year, Voyager 1 showed a sharp drop of charged particles of energy that are produced within the heliosphere.
Consequently, scientists expected that the direction of the magnetic field in space confirm the output of the nave of the solar system, which has not happened in a prompt manner.
“The Voyager crew needed time to consider the evidence and make sense of them. But now we can answer the question you’ve all been waiting for: Are we there? Yeah, we” concluded Stone.
