" .. Data gathered during the first few passes has revealed that ammonia abundances vary quite a bit from place to place
— a discovery that surprised the mission team.
"Most scientists have felt that, as soon as you go down a little bit into Jupiter, everything would be well-mixed, and we're finding that that's just not true at all," Bolton said. "There's structure down deep, but it doesn't seem to match the zones and belts.
" .. Juno's measurements during the first few close passes also show that Jupiter's magnetic field is nearly two times stronger than scientists had predicted. And the probe's gravity data suggest that "there's a lot of strange, deep motions that possibly are going on inside of Jupiter,"
" .. the particles associated with Jupiter's auroras seem to be different than the ones responsible for Earth's most stunning light shows, study team members said.
"We can see that it doesn't work exactly like we expected, or as the Earth does," Bolton said. "We haven’t been able to see particles necessarily going up and down in both directions like we would've expected to cause the aurora. So there's definitely some strange phenomena that we still need to comb through and understand better."http://www.space.com/36999-jupiter-myst ... probe.htmlhttp://www.space.com/37005-jupiter-fuzz ... -juno.html
" .. There seems to be a fuzzy core, and it may be much larger than anybody had anticipated," Bolton said Thursday (May 25) during a NASA press conference announcing the first detailed science results from Juno's mission.This core may even be partially dissolved
, Bolton said, adding that Juno's initial observations are also consistent with "some deep motions or zonal winds" occurring far beneath the enormous planet's cloud tops."
Does Jupiter's core mix the atmosphere, like a paddle-stirrer?http://www.latimes.com/science/sciencen ... story.html
" .. The Juno Microwave Radiometer, which probed hundreds of kilometers beneath the surface, found a remarkable level of organization — including a strange band of ammonia sitting right above the equator that extends deep into the planet."
" .. In fact, this band of ammonia seems to have dynamics somewhat reminiscent of an atmospheric circulation pattern on Earth known as a Hadley Cell — even though that pattern requires a surface like Earth’s land or oceans to work."
" .. results show that Jupiter’s magnetic field might actually be generated higher up, in the shallower layer of molecular hydrogen
(which is strange, since molecular hydrogen is a neutral compound).
“That’s very significant,” John Connerney .. "
