天文学家首度确认海王星上存在极光现象，由 NASA 韦伯太空望远镜所发现，补上了太阳系四颗巨行星极光观测的最后一块拼图。这也是我们首次直接捕捉到这颗最远行星的极光辉光与光谱特征。海王星位于太阳系边缘，距离太阳约45亿公里，是一颗冰冷巨行星。自 1989 年航海家二号飞掠海王星后，这颗遥远行星便再无太空船造访。如今韦伯太空望远镜首度捕捉到海王星上明亮的极光活动。这项突破得益于韦伯望远镜优异的近红外灵敏度，不仅能拍下极光发出的辉光，还能透过光谱清楚辨识代表极光活动的重要指标：三氢阳离子（H₃⁺）。这种离子也曾在木星、土星与天王星的极光中被侦测到，被视为气体行星极光的重要证据。与地球或木星不同，海王星的极光并不集中于南北极，而是分布在行星的中纬度地区。这是因为海王星具有异常倾斜的磁场结构，其磁轴与自转轴倾斜达 47 度，这一特征最早由航海家二号所发现。
