Jupiter looks different for researchers after examining data from NASA’s Juno mission


“We thought it was uniform inside and relatively boring. What we’re finding is anything but that. It’s very complex. Jupiter from the poles doesn’t look anything like it does from our usual view,” he added. Observations and data showed Jupiter’s previously unseen poles which are gigantic cyclones spanning 870 miles. Wells of ammonia form giant and violent weather systems in the deep atmosphere, without being consistently mixed. Jupiter appears to have a band around its equator high in ammonia abundance. “Jupiter’s north pole doesn’t look like the south pole,” Bolton said. Imaging also revealed intriguing cloud features. Possibly it’s snowing on Jupiter. Juno revealed that Jupiter’s magnetic field is 10 times stronger than the strongest magnetic field on Earth and and twice as strong as anticipated, exceeding researchers’ expectations. “Already, we see that the magnetic field looks lumpy: It is stronger in some places and weaker in others. This uneven distribution suggests that the field might be generated by dynamo action closer to the surface, above the layer of metallic hydrogen,” researchers said. Juno also encountered Jupiter’s huge auroras. The Juno mission was designed to collect data and observations that will reveal the origin and evolution of the gas giant.
