Posted on 09/08/2012 9:16:52 PM PDT by SunkenCiv
Explanation: Launched on a grand tour of the outer planets in 1977, by good fortune the twin Voyager spacecraft were also headed in the general direction of the Sun's motion relative to nearby stars. Thirty five years later, Voyager 1 appears to be nearing the boundary of the Sun's heliosphere and interstellar space. Of course the heliosphere is the realm of the Sun defined by the influence of the solar wind and the Sun's magnetic field. But how can you tell when your spacecraft crosses the boundary into interstellar space? One clue would be a sudden increase in the detection of energetic cosmic rays. The high energy particles stream through interstellar space accelerated by distant supernovae in our galaxy, but are normally deflected or slowed by the heliosphere. Covering a 12 month period (September 2011 to 2012), this plot does show a dramatic increase in the rate of cosmic ray particle detection in past months by the Voyager 1 spacecraft. Voyager 1 is now 18 billion kilometers (17 light hours, 122 Astronomical Units) from the Sun and may soon be the first spacecraft from Earth to enter the realm of the stars.

It’s just amazing that we have the ability to send probes into interstellar space.
:) And it’s only taken us 35 years to get there.
Hey, it’s still against the whole Constitution so, go sit in the corner! ;’)
Besides, you don't want me in the corner, I always managed to find trouble there. ;)
Morning or evening? (old soviet joke)
wait.. we’re still receiving data from voyager 1 ?
In the time before Muslim-coddling became a duty of NASA, we really DID know how to build things right!
We all need to thank the muslims for thier technology.
Rocket scientists.....ha!......they left out every other month. How smart can you be if you don’t know the months of the year? I’ll bet they show up for work on Sunday. “You mean it’s not Monday?”
