According to a NASA ambassador, NASA’s Juno spacecraft has made an intriguing discovery in Jupiter’s orbit: The small spacecraft has reportedly detected an FM radio signal coming from Jupiter’s largest moon, Ganymede.
It is almost certainly a natural signal, the ambassador said.
“It’s not ET,” Patrick Wiggins, one of NASA’s ambassadors to Utah, told the local Utah news station KTVX reports. “It’s more of a natural feature.”
The intriguing obscurity remains shrouded in mystery. No other outlets appear to have confirmed Wiggins ‘remarks, and there does not appear to be any scientific paper or press release that matches Wiggins̵
The signal was probably caused by electrons oscillating at a lower speed than their spin, amplified radio waves significantly according to KTVXreporting. The process, known as cyclotron masses instability (CMI), is also behind the aurors on Jupiter, which Juno observed in 2017.
In other words, the discovery did not come as a shock, especially considering that they were picked up near Jupiter’s polar regions, where magnetic field lines connect to Ganymede.
We have known about this “decametric radio emission” originating from Jupiter since the 1960s. On Earth, these signals largely coincide with the Wi-Fi signals we use to surf the web, which ABC4 points out.
Juno was only able to spot the radio emission for five seconds as it orbited Jupiter at 50 kilometers per second, Wiggins said.
