Enhanced E-region ionization produced by the aurora can be used to reflect signals from over-the-horizon radars and thus enable those radars to better monitor aviation in Arctic regions.
Using 1D and 2D data sources as model constraints yields fine-scale insights into real-world aurorae.
Charged particles escape our atmosphere following Earth’s magnetic field and constitute a main source of matter that modulates Sun-Earth interactions.
Magnetic reconnection events less than 2 Jovian radii above the planet’s cloud tops could explain why Juno has yet to observe a source for Jupiter’s polar aurore.
Researchers present a new pattern-finding technique to better estimate missing data on ionospheric plasma velocities.
Over 2 decades, Cluster has shed light on the auroral acceleration region, where parallel electric fields send charged particles on a collision course with the atmosphere.
Spacecraft observations support the mechanism for explaining auroral dunes observed from the ground by citizen scientists.
Researchers have identified a high-latitude phenomenon that looks remarkably like a tropospheric hurricane, with spinning arms of plasma and a shower of electrons.
Juno spacecraft observations provide the first global description of dawn storms in Jupiter’s aurorae, from their initiation to their end.
The auroral feature, first spotted by amateur astronomers in 2015, likely traces high-altitude atmospheric waves.
