NASA’s Juno mission has discovered a world of cyclones at Jupiter’s north Jovian pole, a region of cooler stratospheric haze. The cyclones drift to the pole through a process the researchers refer to as “beta drift” via JunoCam and Jovian Infrared Aurora Mapper. The cyclones oscillate around their centres and can drift clockwise around the pole. Juno has also been making recurring flybys of the innermost Jovian moon, Io, revealing evidence of subterranean magma flows below its surface. These cooling flows could explain how Io’s volcanoes erupt, as about 10% of the moon’s subsurface has these flows. Juno Spots Colliding Jupiter Cyclones and Magma Beneath Io’s Surface As per the data presented by NASA at the European Geosciences Union General Assembly on April 29, Juno has observed a large central cyclone over 1,800 miles wide, encircled by eight slightly smaller cyclones. These weather systems, blowing at speeds over 100 miles per hour, interact through a phenomenon called beta drifts — similar to Earth’s cyclones but progressing to Jupiter’s pole. Once enabled, researchers could visualise both visible …
