A new analysis of three space storms reveals the mechanisms of particle loss from the Van Allen belts.
Variation in the orientation of flux rope features in Mars’s magnetotail suggests that some of them form on the planet’s Sun-facing side and travel to the night side.
Recalibrated and reanalyzed data from the Voyager flybys of Jupiter 40 years ago, presented in a series of papers in JGR: Space Physics, show the value of archival data.
Researchers make the first short-term observation of sodium flares in Mercury’s exosphere.
A new study finds that the ionospheric anomaly over the Weddell Sea is likely influenced by proximity to auroral energy input, rather than by tilting magnetic fields.
With a dose of fiery plasma, the secondary arcs of Jupiter’s aurora shine bright.
In forecasting the effects of solar storms, understanding how they subside—and not just how they arrive—will be crucial.
New calculations show that lightning-triggered plasma waves in Earth's magnetosphere absorb energy from slow particles and energize electrons to levels that can damage satellites severely.
When the Earth's and the Sun's magnetic fields meet, they realign in explosive and mysterious reconnections. Data suggest that plasma waves called kinetic Alfvén waves play a key role.
New research suggests that Jupiter's magnetic field replenishes its stock of plasma during lulls in solar activity, creating spectacular displays when a solar storm hits.
