Press release: “How Jupiter’s unusual magnetospheric topology structures its aurora” on Sciences Advances

 

BEIJING—For more than twenty years, Jupiter’s auroras have been explained through the theoretical lenses of Earth’s auroras, despite some striking differences between the two planets’ lights. Some aspects of it, including the bright persistent aurora near the Jovian polar caps that are generally dark at the Earth, have puzzled researchers for decades.

Now, thanks to the outstanding discovery made by a team of scientists led Dr. Zhang Binzheng (Hong Kong University) and Dr. Yao Zhonghua (Institute of Geology and Geophysics, Chinese Academy of Sciences), who is also the leader of the ISSI-BJ International Team “The morphology of auroras at Earth and giant planets: characteristics and their magnetospheric implications”, we have obtained new valuable insights on Jupiter’s distinctive auroral morphology. The research results, retrieved thanks to supercomputer simulations, have been published on the highly prestigious scientific journal Science Advances on April 9, 2021.

These findings challenge the current widely accepted explanations of Jupiter’s aurora and will revolutionize textbooks on the topic. As stated by one of the contributors, Denis Grodent (Liege University, Belgium),”…the near-pole emissions have been discovered for more than twenty years by the Hubble telescope, now we finally understand why they exist at Jupiter but not at Earth.”.
