Not aliens, sadly.
This is caused by high energy electrons interacting with Ganymede's magnetic field. So not artificial.
Quoting: Sepheryn I was gonna say the same thing. The article headline should say that it picked up EM radiation within the FM radio band range (88-108MHz) not that it picked up FM radio "signals". That word has wrapped up in it the implication of artificially constructed transmission meant to convey information of some kind, so to call it a signal is somewhat misleading. Mind you, it's still interesting as there are not too many discovered natural sources of radio emissions besides extreme stellar events. It's almost if it's a different type of 'signal'. "the implication of artificially constructed transmission meant to convey information of some kind" You know what that means.
