Ganymede’s signal
NASA’s Juno space probe has made an exciting discovery in Jupiter’s orbit, according to a NASA ambassador: the small spacecraft has detected an FM radio signal coming from Jupiter’s largest moon, Ganymede.
It’s almost certainly a natural signal, the ambassador said.
“It’s not ET,” Patrick Wiggins, one of NASA’s ambassadors in Utah, told the local Utah news station. KTVX Reports. “It’s more of a natural function.”
The intriguing blurb remains shrouded in mystery. No other media appears to have confirmed Wiggins ‘remarks, and there does not appear to be any scientific article or press release corresponding to Wiggins’ claims. Futurism reached out to Wiggins and NASA for more details on the claim, and we’ll update the story if we have any news.
As expected
The signal was likely caused by electrons oscillating at a speed lower than their spin, greatly amplifying the radio waves, according to KTVXreports of. The process, known as cyclotron maser instability (CMI), is also the cause of the auroras on Jupiter that Juno observed in 2017.
In other words, the discovery came as no shock, especially since they were picked up near the polar regions of Jupiter, where magnetic field lines connect to Ganymede.
We have known about this “decametric radio broadcast” emanating from Jupiter since the 1960s. On Earth, these signals roughly coincide with the Wi-Fi signals we use to surf the Web, such as ABC4 points out.
Juno was only able to detect the radio show for five seconds as it circled Jupiter at 50 kilometers per second, Wiggins said.
