WASHINGTON Thirty-five years after its launch, Voyager 1 appears to have travelled beyond the influence of the Sun and exited the heliosphere, according to a new study appearing online today.
The heliosphere is a region of space dominated by the Sun and its wind of energetic particles, and which is thought to be enclosed, bubble-like, in the surrounding interstellar medium of gas and dust that pervades the Milky Way galaxy.
On August 25, 2012, NASA's Voyager 1 spacecraft measured drastic changes in radiation levels, more than 11 billion miles from the Sun. Anomalous cosmic rays, which are cosmic rays trapped in the outer heliosphere, all but vanished, dropping to less than 1 percent of previous amounts. At the same time, galactic cosmic rays cosmic radiation from outside of the solar system spiked to levels not seen since Voyager's launch, with intensities as much as twice previous levels.
The findings have been accepted for publication in Geophysical Research Letters, a journal of the American Geophysical Union.
"Within just a few days, the heliospheric intensity of trapped radiation decreased, and the cosmic ray intensity went up as you would expect if it exited the heliosphere," said Bill Webber, professor emeritus of astronomy at New Mexico State University in Las Cruces. He calls this transition boundary the "heliocliff."
In the GRL article, the authors state: "It appears that [Voyager 1] has exited the main solar modulation region, revealing [hydrogen] and [helium] spectra characteristic of those to be expected in the local interstellar medium."
However, Webber notes, scientists are continuing to debate whether Voyager 1 has reached interstellar space or entered a separate, undefined region beyond the solar system.
"It's outside the normal heliosphere, I would say that," Webber said. "We're in a new region. And everything we're measuring is different and exciting."
That is very and what we need to be doing more of as a nation. Push the boundaries, explore beyond what we know, and discover!
At least it didn’t bounce off of the heliopause.
As my Dad always said when I went out to ride my bike, “Write if you get work...”
Well done, V1....
NASA would certainly serve us better as a modern Lewis and Clark agency with private industry following to open the frontier.
11 billion miles from the sun in 35 years, meh...
Obama spent 6$ trillion in four.
Actually, a very cool report, but the sun is at a very weak solar max and I would guess the heliosheath is somewhat compact.
Nothing leaves the heliosphere!
There was a time when the US was bold enough to accomplish this. Now, we’d rather pay for federally funded abortions, sex reassignment surgeries, and all of the other freebies our government bought votes with.
Confusion! How does this ‘reach out’ and help Muslims feel better about themselves. Mohammed didn’t launch interstellar probes so we should not either. It’s offensive.
We got our money’s worth out of this one.
an interesting bttt
V’Ger will return ;-)
And yes I know it was Voyager 6 in the movie.
Another era, another time.
My daughter was a jet mechanic on the 117 and 22. She always knew of my lost over the A12/SR71s and one day she took me to the Tucson museum to see the one there. Keep in mind her then-job working on the best of the best and the fact she had never seen one of these beasts in the flesh. in the flesh.
Long story short her mind could not grasp that it was built 50 years ago. And on the engine they had on display with mechanical actuators consisting of wheels and ‘rubber bands’, I thought she was going to have ‘a moment’.
What we did then/that era, in space and aeronautics will likely never be repeated until warp drive becomes real. Thanks to our Govt.
Edit - Lost = Lust
How long does it take to get “data” back from this craft ?
From a different report,
“”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.”
I bet it tastes like microwave chicken...
Sometimes I think Voyager will be sending messages back to a world reduced to scavengers killing each other with sticks for a potato.
“The signal from Voyager 1 takes approximately 17 hours to travel to Earth.” http://voyager.jpl.nasa.gov/news/voyager_1_new_region.html
It will. I do not doubt it.
probably just the Romulan Neutral Zone...
Correct. Another way to look at it: One light-day is about 16 billion miles, so it takes approx (11/16)*24=16.5 hours.
A bit more than 17 and a half light hours out I believe.
If you haven't seen it, you must see John Glenn's space capsule at the Smithsonian Air and Space Museum. Little larger than a trash can. Toggle switches and gauges. The Right Stuff.
New Horizons is making pretty good time on the way to its 2015 flyby of pluto. Its a little over 3 and a half light hours from us now. We’re catching up now because we’ve come from behind the sun and are headed in the same direction for the next couple of months.
A vestige of American ingenuity that may outlast any recent examples. Truly incredible.
I’d love to but no way I fly east under TSA BSand it’s now too far for me to drive. But I wish I could.
I have been to March, Edwards, Davis and Holloman museums and the Holloman/Almogordo New Mexico museum has some VERY cool toys. The rocket sleds are a trip. The Atlas rocket motor is pretty small too...NOT!
I love me some aircraft/space junk!
Oh and the UFO museum at Roswell ;)
“Star Trek: The Motion Picture”—because bald women are so hot!
I remember the controversy. People were aghast! At least where I was in upstate NY. BALD WOMAN?!?!?!?
It was a controversy?
Up in small town America, church ladies were having fits. It was like NUDITY!!! No self respecting woman would shave her head!
I was in the sticks ;) But yea, people op there were aghast.
We used to have a space museum at the community college in Jackson Michigan because a couple of the early astronauts were from the area. (McDivitt and White) they had a cooked Gemini Capsule inside, a couple of rocket engines, moon rocks, and a full sized mockup of a rocket.
I believe that stuff all went into storage or to other museums.
Sucks when any museum closes regardless of size. But people are now dissuaded from placing value on history. How can one have an interest in things they never learn of or even know exist? And thus the root of many current problems.
Thanks fieldmarshaldj, and an extra topic for APoD members.
even the right stuff can turn into a dick
...appears to have travelled beyond the influence of the Sun and exited the heliosphere, according to a new study appearing online today.Still no sign of the theoretical Oort cloud of comets, but that's perfect for theoreticians. "Whales speak French at the bottom of the sea" ping.
voyager and the oort cloud

Ah were wrong. Apparently the stuff from Jackson is now in Kalamazoo MI. and it wasn’t a Gemini capsule it was the Apollo 9 capsule.
Glad it’s still out there being seen.
Wow, I never even considered people would have that reaction. I was just always genuinely perplexed as to why Kirk and...7th Heaven Dad were so smitten by her baldness.
Here are where all the Apollo capsules are currently located.
I’m somewhat mathematically challenged so forgive me.
I’m trying to get a handle on the speed of the “radio” signal vs. the speed of light.
My grandfather had business dealings with Jim McDivitt after he left the space program. I used to go with granddad to McDivitt’s office to be awestruck.
I was amazed. I was like 13-14ish when it came out (79or so wasn’t it?) and clearly remember the women in our fairly pious little hollow being frazzed over it. How they got to some kind of immoral nudity place I’ll never know. But they did. Of course they always wore headcovering/kerchifs to (our Catholic) church so....
Glad I’m not there anymore ;)
If you noticed her costume, they weren’t looking at her bald head.
I know I wasn’t at the time. Persis Kambatta (sp) was hawt!
All I know is that there isn’t much of anything out there. It’s like really, really, empty.
What is needed is a “brute force” probe, that is basically an armor plated ball with an engine out the back. And not just any engine, but an advanced ion drive.
It would be the first probe designed entirely for the exploration of deep space. Once outside the solar system, the armor plates would open, so the equipment inside would not have been degraded by radiation and particles within the solar system.
and commierado has entered another dimension, the libtard dimension where up is down, right is left, right is wrong.
