Solar Properties Rival for Control of Mars’s Bow Shock

by M. Liemohn 9 July 20194 May 2022

While most planetary bow shocks are controlled by the solar wind, at Mars the solar EUV flux is equally important.

Red and Green Aurora Stop and Go for Different Reasons

by Viviane Pierrard 5 July 201911 August 2022

Green-line arc is found to be embedded within large-scale upward field aligned currents while red-line-only arc is found to be associated with low-energy precipitation bursts.

Data Mining Reveals the Dynamics of Auroral Substorms

by Mark Zastrow 31 May 201916 November 2021

An analysis of 5 decades of satellite data has pieced together the most comprehensive picture yet of substorms, the magnetic disturbances that cause surges of aurora.

Probing the Origin of a New Celestial Phenomenon

by Terri Cook 15 March 201921 February 2023

The first statistical study of STEVE events suggests that the appearance of these narrow ribbons of light is closely correlated with violent disturbances in Earth’s magnetosphere.
