FM radio signal found from Jupiter’s moon

A spacecraft orbiting Jupiter has discovered an FM radio signal from Ganymede, one of the gas giant’s moons. This discovery marks the first detection of a Ganymede signal.

Patrick Wiggins, a NASA ambassador to Utah, has warned that they are probably not aliens, according to KDFW.

“It’s not ET,” Wiggins said. “It’s more of a natural function.”

The spacecraft, called Juno, was moving through a region of Jupiter where magnetic field lines can connect with Ganymede’s moon. It was then that Juno picked up the radio source.

Juno was sent to study how Jupiter formed and evolved over time.

“Juno’s main goal is to reveal the history of the formation and evolution of Jupiter. Using long-proven technologies on a rotating spacecraft placed in an elliptical polar orbit, Juno will observe Jupiter’s gravity and magnetic fields, atmospheric dynamics and composition, and evolution, ”according to NASA.

It was electrons, not aliens, responsible for the moon’s radio broadcasts.

Through a process called maser cyclotron instability, electrons oscillate at a slower speed than they rotate, causing them to rapidly amplify radio waves.

Although this was an important discovery, the orbiting spacecraft could only pick up the radio broadcasts for five seconds. Juno passed at a blinding speed of 111,847 mph. It’s fast enough to cross the whole of the United States from coast to coast in just under two minutes.
