These Nearest-ever Photo of Jupiter are "Like Nothing we have seen Before", Says NASA

NASA presently shared the majority detailed images of Jupiter that humanity has ever seen, and no one was prepared for how unique the biggest planet in our Solar System would be close-up.
The latest images were taken by the Juno space probe, which entered Jupiter's orbit in July after a five-year trek across the Solar System. The spacecraft made its first flyby of the planet previous week, and got closer than any other spacecraft in record.
It took NASA 1.5 days to download the photo from this historic 6-hour flyby, but the haul – showing before unseen storm systems and weather activity, plus the1st -ever images of Jupiter's north pole – have been worth the wait.
"1st glimpse of Jupiter's north pole, and it looks like nothing we have seen or likely before," says principal researcher of the Juno mission Scott Bolton, from the Southwest Research Institute in San Antonio.
"It's bluer in colour up there than extra parts of the planet, and there are a lot of storms."Unlike the familiar striped look of Jupiter's mid-section, the north pole, seen in the photo above, reveals a mess of swirling hurricane-like storms.
"There is no sign of the latitudinal bands or zone and belt that we are used to – this image is barely recognizable as Jupiter," says Bolton. "We're considering signs that the clouds have shadows, possibly representative that the clouds are at a higher altitude than other features."
Another oddity is the lack of a hexagon formation at the north pole, which researchers predictable to find, seeing as the Solar System's other resident gas giant – Saturn – sports such a crown.
"Saturn has a hexagon at the north pole," says Bolton. "There is nothing on Jupiter that wherever near resembles that. The biggest planet in our Solar System is truly unique."
Along with the photo of the north pole, the Juno group used an infrared device – the Italian Space Agency's Jovian Infrared Auroral Mapper (JIRAM) – to analyse Jupiter's polar regions in infrared wavelengths.
In addition to enlightening warm and hot spots dotted throughout Jupiter's north and south poles, JIRAM also gives us our 1st glimpse of the planet's southern aurora (seen below).
"Waves detect the signature emissions of the lively particles that generate the massive auroras which encircle Jupiter's North Pole. These emissions are the strongest in the Solar System. Now we are going to try to figure out where the electrons come from that are generate them."
NASA researchers have only now begin analysing the data from the probe's first sweep of the planet, but with 35 extra orbital flybys yet to come, one thing's for sure: Juno's only just in progress spilling Jupiter's secrets.
"It's going to be a flood," Juno project researcher Steve Levin from NASA's Jet Propulsion Laboratory told Amina Khan at the Los Angeles Times. "Like drinking from a fire hose."
