Citizen scientists provided images of sub-auroral STEVE (Strong Thermal Emission Velocity Enhancements) showing fine-scale green features with narrow streaks propagating poleward toward STEVE.Read More »Space Science & Space Physics
Updating a model developed during the Voyager flybys will enable better mission planning and a deeper understanding of Juno data.Read More »Climate Change
A new book describes recent results defining the many pathways and foreshock, bow shock, magnetosheath, and magnetopause phenomena connecting the solar wind to the dayside magnetosphere.Read More »Natural Hazards
Solar-induced geomagnetic activity and mass strandings of whales and dolphins on shorelines both show seasonal patterns, but the beachings likely result from multiple environmental factors.Read More »Space Science & Space Physics
Naval radio signals may cause the formation of a barrier observed during geomagnetic storms that is seemingly impenetrable by relativistic electrons.Read More »Space Science & Space Physics
Lyman-alpha emissions convey a major part of the solar-flare photon energy reaching Earth and play a significant role in flare-driven enhancements of ionospheric conductivity.Read More »Natural Hazards
Heliospheric imaging data can be used in ensemble modeling of CME arrival time at Earth to improve space weather forecasts, treating the solar wind as a 1-D incompressible hydrodynamic flow. Read More »Atmospheric Sciences
A layer of nickel of cosmic origin, which exists between 80 and 110 km high in Earth’s atmosphere, has been modeled for the first time, including dynamics and complex neutral and ion chemistry.Read More »
