Voyager 1 Has Left the Solar System, Says New Study, University of Maryland
"Voyager 1 appears to have at long last left our solar system and entered interstellar space, says a University of Maryland-led team of researchers. Carrying Earthly greetings on a gold plated phonograph record and still-operational scientific instruments - including the Low Energy Charged Particle detector designed, built and overseen, in part, by UMD's Space Physics Group - NASA's Voyager 1 has traveled farther from Earth than any other human-made object. And now, these researchers say, it has begun the first exploration of our galaxy beyond the Sun's influence."
"Other models envision the interstellar magnetic field draped around our solar bubble and predict that the direction of the interstellar magnetic field is different from the solar magnetic field inside. By that interpretation, Voyager 1 would still be inside our solar bubble. The fine-scale magnetic connection model will become part of the discussion among scientists as they try to reconcile what may be happening on a fine scale with what happens on a larger scale."
