Our take: Scientists are unable to make precise guesses of how long it will take for Voyager 1 to move out of the solar system as they found that the magnetic field has increased. Eryn Brown, journalist of the Los Angeles Times reports on the scientists' findings:
"Voyager 1, the spacecraft famous for beaming back striking photos of Jupiter, Saturn and their moons more than 30 years ago, has made still another surprising discovery: the existence of an unexpected zone at the very edge of the solar system.
It had been thought that the NASA probe was already passing through the outermost section of the solar system on its way toward the heliopause –– the boundary where the solar wind ends and interstellar space begins. For that reason, the existence of yet another district at our cosmic neighborhood's edge was completely unexpected, said Stamatios Krimigis, a solar physicist at the Johns Hopkins Applied Physics Laboratory in Laurel, Md., and leader of the team that operates Voyager's low-energy charged particle instrument."
