There are FM radio signals coming from one of Jupiter’s moon As we generally relate FM to radio, which in turn we connect with communication, chances are some people might see it as a proof of alien life Are they trying to contact us through radio waves? Are they friendly? Are they dangerous?

Before someone starts to panic it should be notified that these radio waves aren’t exactly coming from a communication device of any super-intelligent alien life It’s simply one of the non-living space phenomena

The FM radio signals were picked up by a spacecraft called Juno It was orbiting the gas giant when it detected the waves from Ganymede, one of Jupiter’s 79 moons Previously, no activity or signal had ever been detected from this particular moon

It’s not ET,” said Patrick Wiggins speaking to Fox “It’s more of a natural function” Wiggins is a NASA ambassador from Utah

The signals mostly originated from electrons As much as radio signals from extra-terrestrials would be exciting (or scary according to the hundreds of alien invasion movies from Hollywood), it is simply a natural phenomenon from a *probably* lifeless planet There is a process called cyclotron maser instability It is a process that can occur in electromagnetic fields The process causes electrons within the whirl to oscillate much slower than their spin rate As a result, all the electromagnetic and radio waves in the surrounding location can get amplified This amplified frequency was thereupon picked by the spacecraft Juno was moving through a region of Jupiter where magnetic field lines of the planet can connect with the Ganymede moon This is where the signals were picked as well

The same electrons that cause these radio signals can also be responsible for creating auroras in the far-ultraviolet spectrum One such instance was captured by the cameras about Juno spacecraft

In 2011, NASA sent a space probe named JUNO out into space It was a part of NASA’s “New Frontiers Program” The program consists of a series of missions where NASA aims to explore our entire solar system and strengthen our understanding of space

The probe was aimed towards Jupiter in order to study the planet and discover more about how it was formed or how it evolved over time It entered Jupiter’s orbit in 2016 According to the official website, Juno has some state of the art technology aboard and it will “observe Jupiter’s gravity and magnetic fields, atmospheric dynamics and composition, and evolution”
