Amazing pictures show cyclones swirling above Jupiter鈥檚 poles

The best close-up images ever of Jupiter reveal surprising cyclones and ammonia patches that are forcing a rethink of our understanding of the planet

These incredible new Jupiter pictures are helping to turn theories about the planet upside down.

快猫短视频 reported the first sneak peak of the data from NASA鈥檚 Jupiter orbiting Juno mission at the beginning of this month, now the mission scientists have published spectacular new pictures and over forty new papers.

Juno has revealed monstrous cyclones churning over Jupiter鈥檚 poles that are more turbulent than scientists expected. The $1.1bn spacecraft spotted the chaotic weather at the top and bottom of Jupiter once it began skimming the cloud tops last year, surprising researchers who assumed the giant gas planet would be relatively boring and uniform.

鈥淲hat we鈥檙e finding is anything but that is the truth. It鈥檚 very different, very complex,鈥 said Juno鈥檚 chief scientist Scott Bolton of the Southwest Research Institute.

The finding of dozens of huge cyclones hundreds of miles across mean that the poles look nothing like Jupiter鈥檚 equatorial region, which is instantly recognisable by its stripes and Great Red Spot.

鈥淭hat鈥檚 the Jupiter we鈥檝e all known and grown to love,鈥 said Bolton. 鈥淎nd when you look from the pole, it looks totally different. I don鈥檛 think anybody would have guessed this is Jupiter.鈥

Citizen scientists processed the images to reveal the impressive level of detail that can be seen, although they do not give an accurate representation of what you would see with the naked eye from Juno鈥檚 position.

Juno reached Jupiter and began its first orbit on 4 July last year. It travels around the gas giant once every 53 days, with 33 planned pole-to-pole circuits in all, encircling the entire planet bit by bit.

Each pass takes just two hours, with the journey consisting of a trip over the north pole, round the planet, over the south pole, and then back out into space. The next pass will be in July, with investigators targeting the Great Red Spot.

Besides polar cyclones, Juno has spotted white ice caps on Jupiter 鈥 frozen bits of ammonia and water. Juno has also detected an overwhelming abundance of ammonia deep down in the atmosphere, and a surprisingly strong magnetic field in places 鈥 roughly 10 times greater than Earth鈥檚.

Juno鈥檚 findings are 鈥渞eally going to force us to rethink not only how Jupiter works,鈥 said Bolton.
