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.
Maps reveal how the Sun’s magnetic field evolves through solar cycles.
Short-term funding strategies present serious problems for programs like solar activity studies, where observations and analysis span decades or longer.
Scientists demonstrate the capabilities and limitations of the mathematical model used to calculate solar irradiance using measurements from NASA’s Mars Atmosphere and Volatile Evolution (MAVEN).
Analysis of magnetic fields on the Sun's surface offers a new clue on why sunspots appear.
Faced with the prospect of a large data gap in solar irradiance records, scientists take steps to ensure that this key climate variable stays monitored.
