A Close-in Look at Saturn’s Periodic Space Bubble
When it comes to Saturn’s space environment, summer wins over winter in controlling the periodic flows of electrically charged particles and magnetic fields.
Preserving a 45-Year Record of Sunspots
Maps reveal how the Sun’s magnetic field evolves through solar cycles.
Where the Solar Wind Meets Mars
A comprehensive look at how the solar wind is diverted around Mars, including the relative strength of the three biggest forces at work in this region.
The “Magnetic-less” Magnetotail Boundary
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.
Tracing Electric Currents That Flow Along Earth’s Magnetic Field
A new study uses satellite data to examine a worldwide system of electric currents in greater detail than ever before.
Comparing the Accuracy of Geomagnetic Field Models
Improved accuracy and optimization of models could benefit many applications.
A Better Way to Predict Space Storms
A new model of solar winds could reduce false alarms.
Resolving a Mystery of the Ages
High-precision radiometric dates shed new light on the puzzling 600,000-year disparity in the timing of one of Earth’s most pivotal timescale boundaries.
Solar Wind Sets the Magnetosphere Ringing
A combination of data from satellites and ground-based instruments gives new insight into solar wind-magnetosphere-ionosphere interactions.
