The findings could help explain how Jupiter's atmosphere is heated and cooled, according to a study published May 12 in."We wanted to see how quickly the auroras change, expecting them to fade in and out ponderously, perhaps over a quarter of an hour or so. Instead, we observed the whole auroral region fizzing and popping with light, sometimes varying by the second."James Webb telescope reveals 'cosmic tornado' in best detail ever — and finds part of it is not what it seems James Webb telescope spots 'rogue' planet with a cake-like atmosphere barrelling through space without a star Auroras form when high-energy charged particles, often released from the sun, slam into gases in a planet's atmosphere, causing the gas to glow. Jupiter's strong magnetic field scoops up charged particles such as electrons from the solar wind — and from eruptions on its— and sends them hurtling toward the planet's poles, where they put on a spectacle hundreds of times brighter than Earth's. This molecule forms in Jupiter's auroras when energetic electrons meet hydrogen in the planet's atmosphere. Its infrared emission sends heat out of Jupiter's atmosphere, but the molecule can also be destroyed by fast-moving electrons. To date, no ground-based telescopes have been sensitive enough to determine exactly how long Hlasts about two and a half minutes in Jupiter's atmosphere before being destroyed. That could help scientists tease out how much of an effect HGet the world’s most fascinating discoveries delivered straight to your inbox.Jupiter glows in stunning new James Webb telescope imagestoward Jupiter at the same time. Hubble captured the ultraviolet light coming from the auroras, while JWST captured infrared light. "Bizarrely, the brightest light observed by Webb had no real counterpart in Hubble's pictures," Nichols said in the statement."This has left us scratching our heads. In order to cause the combination of brightness seen by both Webb and Hubble, we need to have a combination of high quantities of very low-energy particles hitting the atmosphere, which was previously thought to be impossible. We still don't understand how this happens." In future work, the researchers plan to study the source of this unexpected pattern using additional JWST data as well as observations from Skyler Ware is a freelance science journalist covering chemistry, biology, paleontology and Earth science.
