Voyager 1 and Voyager 2 update

By Amy Woodyatt, CNN

Updated 2:46 PM ET, Tue May 11, 2021

(CNN)One of the Earth's longest-flying spacecraft has detected a "persistent hum" beyond our solar system, according to a new study.

NASA's Voyager 1 launched on September 5 1977, from Cape Canaveral, Florida, aboard a Titan-Centaur rocket, just weeks after its sister craft, Voyager 2.

Although they were initially designed to last five years, more than 43 years after they launched, the crafts are still sending back data as they explore interstellar space.

Instruments aboard Voyager 1, which has moved past the edge of the solar system, through the solar system's border with interstellar space, known as the heliopause, and into the interstellar medium, have detected the sounds of plasma waves, according to research published Monday in the journal Nature Astronomy.

I recently saw some clips of the upcoming season 4 of Discovery. The plot line for the season is about an enormous anomaly and it might be V'ger.

into our dimensional reality.

I called it Star Trek's "Babylon 5 moment."

I thought they might be V'Ger's benefactors.

In Trek, it's Voyager 6 that becomes V'Ger.

The version of ST:TMP on Amazon is shortened. (It's not the Dir's cut). It's missing the scene where Ilia heals Checov, and maybe some other scenes.

We have parts on both Curiosity and Perseverance!

And their parts are generally complex and with tight tolerances. We bitch about it at work, but we can't argue with either the results or the money.

detecting this hum? I am guessing that this hum is being emitted as radio waves?

I thought that space beyond our solar system was a vast, mostly empty space, with the occasional atom scattered about.

Obviously there's enough of a medium out there to allow the hum to propagate through the space median...that is, there's enough gas to allow this hum to propagate...in itself a major finding, after all, from articles I have read prior to the space craft making it to this region, there was all kinds of speculation as to what they would find.

I thought, if I recall right, that they weren't expecting anything but the vast emptiness of interstellar vacuum w/ very few atoms scattered within this medium...

Can you imagine that these craft have been flying over 40+ years?! I wish my car would work that long, ha ha heh...

Again, neat!

Cool but a little creepy. I expected to hear a hum like the monolith in 2001 A Space Odyssey.

Voyager 1 & 2 are incredible crafts that were created by intelligent scientists at NASA!


Here's another computer visualization of the "hum"



Enjoy!

You can't talk in vacuum so deep space never learned the words. Also, it is kind of dark, lonely and creepy out there so humming helps a little.

math heads, who really know why it's exciting!, are turning mental flips.

“The interstellar medium is like a quiet or gentle rain,” said senior author James Cordes, the George Feldstein Professor of Astronomy. “In the case of a solar outburst, it’s like detecting a lightning burst in a thunderstorm and then it’s back to a gentle rain.” ... Cornell research scientist Shami Chatterjee explained how continuous tracking of the density of interstellar space is important. “We’ve never had a chance to evaluate it. Now we know we don’t need a fortuitous event related to the sun to measure interstellar plasma,” Chatterjee said. “Regardless of what the sun is doing, Voyager is sending back detail. The craft is saying, ‘Here’s the density I’m swimming through right now. And here it is now. And here it is now. And here it is now.’ Voyager is quite distant and will be doing this continuously.”


My husband was working at JPL back then as a computer tech, and probably one or both carries some little note from him that JPLers were invited to contribute.
