A new study identifies possible precursors to space weather in the regions encircling sunspots.
A new empirical model of energetic electrons from Van Allen Probes data includes pitch angle analysis, revealing insights about radiation belt energization and loss processes.
A large plasma hole generated by the vertical launch of the Formosat-5 satellite created temporary navigating and positioning errors of up to 1 meter, according to a new study.
A NASA stereo-imaging mission called TWINS continues to push the boundaries of what we know about the region of space close to Earth.
Scientists capture the first complete image of Earth’s luminous geocorona and prove its ecliptic north–south symmetry.
Exploring the relationship between solar extreme ultraviolet radiation flux and 150-km radar echoes.
Most boundaries in space are governed by magnetic fields, but not far behind the Earth, where the field change across the magnetopause plays very little role in the pressure balance relationship.
A new modeling effort could change our understanding of auroral arc formation.
The lower-energy particles may play a larger role in magnetic reconnection than previously believed, influencing space weather near Earth.
A new analysis of three space storms reveals the mechanisms of particle loss from the Van Allen belts.
