| 英文摘要 | The most remarkable feature of the ultraviolet auroras at Jupiter is the ever-present and almost continuous curtain of bright emissions centered on each magnetic pole and called the main emissions. According to the widely accepted theory, it results from an electric current loop transferring momentum from the Jovian ionosphere to the magnetospheric plasma. However, predictions based on this theory have been recently challenged by observations from Juno and the Hubble Space Telescope. Here we review the main contradictory observations, expose their implications for the theory, and discuss promising paths forward. Plain Language Summary The powerful auroras at Jupiter are very different from those at Earth, and the mechanisms generating them differ as well. Their most obvious feature is a relatively continuous auroral curtain surrounding the magnetic poles. The classical explanation for its presence involves an electric current system that causes particles in the magnetosphere to rotate with planet. While these models explain some characteristics of the auroras, recent observations from the NASA Juno spacecraft and the Hubble Space Telescope challenge this theoretical framework. |
