Voyager 1 Enters Unknown Region Beyond the Solar System

The probe Voyager 1, launched into space by NASA for 35 years, appears to have finally crossed the frontier of the solar system and is moved by an unknown region leading to interstellar space, according to a new study released by the American Union Geophysics and will be published in the journal Geophysical Research Letters.

Thus, the ship would have left the heliosphere, the bubble of charged particles emitted by the sun in all directions and envelops our solar system to enter a new field that has never before seen a human artifact.

On August 25, 2012, Voyager 1 saw drastic changes in radiation levels to about 18,000 million miles from the sun trapped cosmic rays in the outer heliosphere and almost disappeared, while the galactic cosmic ray radiation - cosmic coming from outside the solar system, soared to levels not seen since the launch of the Voyager. "In just a few days, the intensity of the radiation trapped in the heliosphere decreased, and the cosmic ray intensity rose as expected if you leave the heliosphere," says Bill Webber, professor of astronomy at New Mexico State University in Las Cruces.

In the article, the authors state that the Voyager 1 seems to have left the main region dominated by the Sun, revealing hydrogen and helium, a characteristic spectrum of what can be expected in the interstellar medium.

However, Webber says, scientists are still debating whether Voyager 1 has reached interstellar space or into a separate region beyond the solar system.

"It's out of the heliosphere normal, I would say that," said Webber to mediate the dispute. "We are in a new region. And all you're measuring is different and exciting."

The Voyager 1 and its twin, the Voyager 2 , were launched 35 years ago from Cape Canaveral with a mission to explore the solar system. The 2 is about 15,000 million km from the Sun between the two have explored the giant planets in our system: Jupiter, Saturn, Uranus and Neptune, and 48 of its satellites.

Their batteries are designed to run until 2025.
