Salt Lake City (KTVXThe Juno spacecraft orbiting Jupiter has detected an FM radio signal from Ganymede. The discovery is the first discovery of the moon.

It’s not an association, “said Patrick Wiggins, one of the NASA ambassadors in Utah. “It’s a more natural job.”

Juno was traveling through Jupiter’s polar region – where magnetic field lines connect to Ganymede – when it crossed the radio source. Scientifically, it is called “decimal radio emission”.

Here on Earth, we know it as Wi-Fi, and we use it every day.

According to, Jupiter’s radio emissions were discovered in 1955, and over the past 66 years, more and more have been discovered about how the signals work.

“A member of the astronomical community in Salt Lake built an amateur radio telescope that could detect electromagnetic radiation from Jupiter,” said Wiggins.

Juno’s mission is to study how Jupiter was formed and how it evolved.

According to NASA, “Juno will monitor Jupiter’s gravity, magnetic fields, and atmospheric dynamics, composition and evolution.”

What caused the radio emissions of Jupiter’s moon? The electrons, not the aliens, cause the signals.

Electrons oscillate at a lower rate than their rotation rate, causing the electrons to amplify the radio waves very quickly. The process is called cyclotron instability (CMI). The electrons that generate the radio signal can also cause auroras in the far ultraviolet spectrum, a phenomenon also observed by the camera in Juno.

The spacecraft watched the moon’s radio emission for only five seconds. It was flying at 50 km per second – screaming 111,847 mph.
