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.
Mary K. Hudson was awarded the 2017 John Adam Fleming Medal at the American Geophysical Union Fall Meeting Honors Ceremony, held on 13 December 2017 in New Orleans, La. The medal is for “original research and technical leadership in geomagnetism, atmospheric electricity, aeronomy, space physics, and/or related sciences.”
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.
Variation in the orientation of flux rope features in Mars’s magnetotail suggests that some of them form on the planet’s Sun-facing side and travel to the night side.
Recalibrated and reanalyzed data from the Voyager flybys of Jupiter 40 years ago, presented in a series of papers in JGR: Space Physics, show the value of archival data.
