The Juno probe was able to see Jupiter from its poles, which revealed a very different picture of the planet than was possible with our usual view. Aurora seen on Jupiter with the Hubble Space Telescope in June 2016, just before Juno arrived at the planet. NASA's Juno spacecraft spotted the chaotic weather at the top and bottom of Jupiter once it began skimming the cloud tops a year ago, surprising researchers who assumed the giant gas planet would be relatively boring and uniform down low. Observations by NASA's Jupiter-orbiting Juno spacecraft are already helping to flesh out this picture; Juno's gravity data suggest, for example, that Jupiter may have a surprisingly large, partially dissolved core, mission team members have said. "We're puzzled as to how they could be formed, how stable the configuration is, and why Jupiter's north pole doesn't look like the south pole", Bolton said. Some of the most handsome data obtained during the flybys are images captured by the spacecraft's JunoCam, which showed massive storm systems on the planet, and allow scientists to understand the planet's atmosphere, climate, and its north and south poles. These are just two of the surprising discoveries made by NASA's Juno spacecraft. A planetary space physicist at the University of Colorado, Fran Bagenal, stated that they were all jumping with excitement when the images of Jupiter came down. The image revealed a cyclone on the Jupiter that's about 600 miles in diameter.

But all her work through the interim period had paid off with a faster recovery than expected.

China dismisses credit downgrade China's credit rating has been downgraded by Moody's Investors Service for the first time since November 1989, from Aa3 to A1. Standards & Poor's, a rival of Moody's, downgraded its outlook during the same month to negative for China. "We knew, going in, that Jupiter would throw us some curves", Scott Bolton, Juno principal investigator from the Southwest Research Institute in San Antonio, said in a press release, "But now that we are here we are finding that Jupiter can throw the heat, as well as knuckleballs and sliders". According to the data, the big belts near Jupiter's equator reach all the way down, while the smaller belts and zones continually evolve into other structures. Along with new data comes a striking new photo of Jupiter, this time showing the sequence of Juno's approach to Jupiter. The results of Juno's initial probe of Jupiter have been published today in the journal Science and in 44 papers in Geophysical Research Letters, encompassing more than two dozen reports. With a magnetic field over 10x more powerful than Earth's, scientists are fascinated by the irregularity and sheer power of Jupiter's magnetosphere. Prior to the Juno mission, it was known that Jupiter had the most intense magnetic field in the solar system. The probe collects most of its information during close flybys over the gas giant's poles, which occur once every 53.5 days. Juno's findings are "really going to force us to rethink not only how Jupiter works", said Bolton. "On our next flyby...we will fly directly over one of the most iconic features in the entire solar system - one that every school kid knows - Jupiter's Great Red Spot. If anybody is going to get to the bottom of what is going on below those mammoth swirling crimson cloud tops, it's Juno and her cloud-piercing science instruments", enthused Bolton.

NASA-in letjelica Juno, koja je prošle godine ušla u polarnu orbitu Jupitera, poslala je dramatične fotografije najvećeg planeta u Sunčevom sustavu. Na njima su vidljivi masivni oblaci u atmosferi plinovitog diva, ogromni cikloni i veliki tokovi amonijaka koji zajedno čine spektakularni vremenski sustav Jupitera. Misija 1.1 milijarde dolara vrijedne letjelice je da "proviri" kroz guste oblake koji prekrivaju planet te sazna kako se formirao Jupiter, a s njim i ostali planeti u Sunčevom sustavu prije više od 4 milijarde godina. - Skakali smo od uzbuđenja kad su stigle fotografije. Morate biti strpljivi, ali nagrade za to su fantastične - rekao je za Guardian fizičar Fran Bagenal sa Sveučilišta u Coloradu, koji se misiji Juno pridružio pri samom početku, prije više od deset godina. Letjelica Juno je putovala gotovo šest godina i pritom prešla 2,8 milijardi kilometara do svoj destinacije, gdje se spustila ispod Jupiterovih pojaseva intenzivne radijacije, uključila instrumente i ušla u orbitu koja prolazi iznad sjevernog i južnog pola planeta. Oko 5000 kilometara iznad smeđe-narančastog pokrova planeta kamera s letjelice je snimila visoke olujne oblake koji se ističu nad ostalima, toliko da se vide i na noćnoj strani planeta (odaje ih blaga refleksija ono malo Sunčeve svjetlosti koja dopire do njih) - Vrijeme na Jupiteru je dramatično. Ono što smo mislili da znamo o Jupiteru, zapravo smo podcijenili - puno je detaljniji i raznovrsniji što ga bliže gledate - rekao je Bagenal za planet koji su neki njegovi kolege prozvali "planetom na steroidima". Jupiter je inače ogromni plinoviti div sastavljen od helija i vodika, a moguće je da ima i čvršću jezgru sastavljenu od težih elemenata (još se Arthur C. Clarke igrao idejom da je jezgra planeta zapravo ogromni dijamant), iako vjerojatno nema definiranu čvrstu površinu. Jupiter je 11 puta širi od Zemlje, a u njega bi stali svi ostali planeti Sunčevog sustava zajedno, od čije je ukupne mase ujedno i 2,5 puta teži. Nazvan je po rimskoj inačici grčkog boga Zeusa, a diči se i sa 67 mjeseca, od čega četiri velika (Io, Europa, Ganimed i Kalisto).
