05:00 in the BBC's radio program Giant hurricanes at Jupiter’s poles, BBC's science correspondent Jonathan Amos summarizes the result of higher than expected multipole intensity of Juno's magnetic field measurements during close passes of the planet, and agrees with the paraphrasing of the potential source of the planet's magnetic field as:
...'rivers of metallic hydrogen' in the atmosphere of Jupiter...
Question: How close of an analogy is this, given what was actually measured? And for that matter, could someone describe what was actually measured? Was it a localized "blip" or does this really show up in the multipole expansion of Jupiter's entire planetary field?
There is a bit more in the BBC's Juno peers below Jupiter's clouds (written by Jonathan Amos), and probably much more in the articles just published in Science Jupiter’s interior and deep atmosphere: The initial pole-to-pole passes with the Juno spacecraft and also Jupiter’s magnetosphere and aurorae observed by the Juno spacecraft during its first polar orbits.
