We tried to send more Chuck Berry, but it only got to Ganymede.

The Juno spacecraft orbiting Jupiter has discovered an FM radio signal coming from the moon Ganymede. The find is a first-time detection from the moon.
Patrick Wiggins, one of NASA’s Ambassadors to Utah, says, “It’s not E.T. It’s more of a natural function.”
Juno was traveling across the polar region of Jupiter, where magnetic field lines connect to Ganymede, and that’s when it crossed the radio source. Scientifically, it is called a “decametric radio emission.”
Here on earth we know it as Wi-Fi. And we use it every day.
According to Britannica.com, Jupiter’s radio emissions were discovered in 1955, and over the last 66 years, more and more discoveries have been made about how the signals work.
Wiggins says, “A member of the Salt Lake Astronomical society once built an amateur radio telescope that could detect the electromagnetic radiation from Jupiter.”
Juno’s mission is to study how the planet Jupiter formed and how it evolved. According to NASA, “Juno will observe Jupiter’s gravity and magnetic fields, atmospheric dynamics and composition, and evolution.”
What caused the radio emissions from Jupiter’s moon? Again, aliens are not sending the signal. Electrons cause the signals. The electrons oscillate at a lower rate than they spin.
This causes the electrons to amplify radio waves very rapidly. The process has an interesting name, cyclotron maser instability (CMI). The electrons that generate the radio signal can also cause auroras in the far-ultraviolet spectrum – which was also observed by the camera on Juno.
What’s a NanoSat? BYU made one they’re calling ‘Spacecraft Selfie Cam’ The spacecraft saw the moon’s radio emission for only five seconds it was flying by at 50 km per second. That is a screaming 111,847 mph. Because Juno was flying so fast, the source of the radio transmission was at least 250 kilometers (155.3 miles) in order for the sensors to pick it up.
So even though this time it wasn’t an alien transmission, Wiggins says “I do believe life is out there, but I’m still waiting for evidence to prove it.”
The radio signal is being called a shorter relative to the same thing that causes the auroras here on earth.
Maybe it’s Jupiters version of Rush Limbaugh
I’m just here for the 2010 references.

Send more Chuck Berry.
Steely Dan did this 40 years ago !!
Beat me by a minute.😏
Wi-fi on HF, who knew?
Sheesh Fred.
We asked you to turn the radio off just before we left for Vacay!
jriver makes software (PC/Apple) that can process the HiRes files and send the digital signal to an external DAC.
Good software for a PC-based server.
The newer “audio computers” provide a significant increase in sound quality with better power supplies and engineering focused on audio, not a PC.
Guess I’m the only one to remember Mars Attacks! The movie. Not the Topps trading cards it was based on!

Ground Control to Major Tom
Ground Control to Major Tom
Take your protein pills and put your helmet on
Ground Control to Major Tom (ten, nine, eight, seven, six)
Commencing countdown, engines on (five, four, three)
Check ignition and may God’s love be with you (two, one, liftoff)
This is Ground Control to Major Tom
You’ve really made the grade
And the papers want to know whose shirts you wear
Now it’s time to leave the capsule if you dare
“This is Major Tom to Ground Control
I’m stepping through the door
And I’m floating in a most peculiar way
And the stars look very different today
For here
Am I sitting in a tin can
Far above the world
Planet Earth is blue
And there’s nothing I can do
Though I’m past one hundred thousand miles
I’m feeling very still
And I… More

Anything but “Today’s Country Hits.” That would be earth-shatteringly awful.
FM’s soundtrack was all 1978 rock—silly movie, great tunes!
Good one to see with a buzz...
One NOT to see buzzed? Alien! Har!
Don’t tell leftists about this. They’ll scour that FM signal looking for someone to ban, deplatform or get fired.
Are they still hiding from the phone cops?
Probably Mexican Music. They have the strongest transmitters.
The on-off knob was broken!

Now we have to listen to Jovian replays for the next 700 years until we get back to pull the plug. ( grin)
Was it Assimov who said that Adolf’s speeches will be travelling through the universe at the speed of sound for 800 years...
Before they reach empty space...?
