SALT LAKE CITY (ABC4) – 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.

Save us? Nah. They're just coming to claim what's left after we're gone.

If you want to listen to what radio waves from Jupitur sound like here you go

Imagine aliens contacting us on January 19th and wanting to speak to the US President

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).

Good, good morning. Here at Q101.7, the morning Zoo Crew plays only Ganymede's most popular tracks. This one goes out to HAL with a super long distance dedication:

"All these worlds are yours except Europa Ganymede. Attempt no landing there."

Its just the Ganymede Classic Rock radio station playing such golden oldies like Nirvana and Limp Bizket.

I checked it out but they were playing Bryan Adams. The search for intelligent life continues...

It's either the effect of oscillating electrons creating radio waves...or it's the protomolecule!

I'm glad I'm not the only one who's brain immediately went to Cowboy Bebop when you read the thread title.
