An international armada of orbiting satellites and ground VLF network join forces to form a “magnetosphere-ionosphere observatory” to size up electromagnetic ion cyclotron waves in the magnetosphere.
A new classification scheme helps researchers distinguish what accelerates the electrons that create auroras.
With a dose of fiery plasma, the secondary arcs of Jupiter’s aurora shine bright.
The unexpected character of the beams, revealed by NASA’s Juno spacecraft, suggests that the processes that produce Jupiter’s auroras are unlike those on Earth.
Scientists have mapped Jupiter's spectacular aurora in unprecedented detail with the Hubble Space Telescope.
