Eldorado Posted January 13, 2021 #1 Share Posted January 13, 2021 NASA recently extended the life of two of its planetary discovery missions, including the Juno mission to Jupiter. Now it's come to light Juno has discovered an FM signal emanating from one of the gas giant's moons, Ganymede. The discovery is not an indication of extraterrestrial life, but it is fascinating nonetheless, given it's the first time it's been discovered coming from the celestial satellite. "It’s not E.T.," Patrick Wiggins, one of NASA’s ambassadors to Utah, said in comments obtained by Fox 8 Cleveland. "It’s more of a natural function."

ChrLzs Posted January 25, 2021 #4 Share Posted January 25, 2021 Hmm. A bit misleading - it's not really 'FM'. The paper does NOT use that term - 'FM' normally refers to a deliberately induced frequency-modulated radio wave designed to carry information. Neither of those bolded bits apply. It is simply two sets of modulated radio wave transmissions caused by the interacting magnetic fields of Jupiter and its moons. Link to comment Share on other sites More sharing options...
