NASA Voyager 1 Probe Encounters New Region in Deep Space

Dec. 03, 2012 RELEASE : 12-416 NASA Voyager 1 Probe Encounters New Region in Deep Space
WASHINGTON -- 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 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."

15. It's kind of.difficult to get.a whale song without whales.
And the crew of the enterprise went back in time on a Klingon ship in order to get those whales, explaining the discovery of transparent aluminum.

16. Star Trek I was the one about the returned Voyager probe.
Star Trek IV is the one about the whales and the Klingon ship and time travel. The probe in that movie was never really identified.

7. Love The Graphic From ArsTechnica... And REMEMBER... The Rest Of The Universe Will See Us Naked...
The Voyagers have both reached the heliosheath at the edge of the Solar System, but Voyager 1 has hit a region of it we didn't know was there.
On the Nekkid Part:
Conservatives should be concerned.

13. That was from the Pioneer spacecraft that preceeded the Voyagers
And, yeah, the conservatives shit bricks when that was published. LTTE in Tulsa, OK were crabbing about 'exporting pornography,' after filling this planet with it.
One Churchlady type suggested that the Pioneers should have featured a picture of 'praying hands.' My evil imagination came up with an image of aliens finding the Pioneer probe, seeing the plaque and remarking: "Ah, how beautiful! Two earth creatures mating!"

9. Some More Details
The space craft is 11.5 billion miles away from Earth and its been travelling for 35 years. For the next 14,000 years it will still be within the Oort Cloud which includes Trans-Neputunian Objects as far away from the Sun as 6 trillion miles.
