Major Press Conference at AGU Today from NASA- VOYAGER ENTERS NEW REGION-here's an intro..... December 03, 2012 PASADENA, Calif. -- NASA's Voyager 1 spacecraft has entered a new region at the far reaches of our solar system that scientists feel is the final area the spacecraft has to cross before reaching interstellar space. Scientists refer to this new region as a magnetic highway for charged particles because our sun's magnetic field lines are connected to interstellar magnetic field lines. This connection allows lower-energy charged particles that originate from inside our heliosphere -- or the bubble of charged particles the sun blows around itself -- to zoom out and allows higher-energy particles from outside to stream in. Before entering this region, the charged particles bounced around in all directions, as if trapped on local roads inside the heliosphere. The Voyager team infers this region is still inside our solar bubble because the direction of the magnetic field lines has not changed. The direction of these magnetic field lines is predicted to change when Voyager breaks through to interstellar space. The new results were described at the American Geophysical Union meeting in San Francisco on Monday. "Although Voyager 1 still is inside the sun's environment, we now can taste what it's like on the outside because the particles are zipping in and out on this magnetic highway," said Edward Stone, Voyager project scientist based at the California Institute of Technology, Pasadena. "We believe this is the last leg of our journey to interstellar space. Our best guess is it's likely just a few months to a couple years away. The new region isn't what we expected, but we've come to expect the unexpected from Voyager." Lots more and graphics, too, at JPL: [ link to www.jpl.nasa.gov] Quoting: Hugh M Eye Brilliant post Hugh Thank you! Quoting: Spittin'Cesium I realize the article has more to do with Voyager's outward journey, rather than the repercussions inward, but are the higher charged particles are trapped in our outer solar system where voyager currently is, bouncing around, or they are finding their way closer to the inner solar system ??? Quoting: TS66 From the Article - 'Scientists refer to this new region as a magnetic highway for charged particles because our sun's magnetic field lines are connected to interstellar magnetic field lines. This connection allows lower-energy charged particles that originate from inside our heliosphere -- or the bubble of charged particles the sun blows around itself -- to zoom out and allows higher-energy particles from outside to stream in. Before entering this region, the charged particles bounced around in all directions, as if trapped on local roads inside the heliosphere'. I'm pretty sure that means the Particles stream in toward the Sun as well as out along these Field Lines. Perhaps this region just arrived at Voyager and not Voyager it?
