New Plasma Wave Observations from Earth’s Magnetosphere
The first simultaneous observations of multiple electromagnetic wave types in Earth’s magnetosphere may inaugurate a new field of inquiry into cross-frequency wave interactions.
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.
Retracing the First Spaceborne Electric Field Measurement
Fifty years ago, a sounding rocket made history by taking the first measurement of an electric field in space. What techniques were used to capture this data?
What Causes Broadband Electrostatic Noise in Space?
Factors that generate electrostatic noise involve how electric fields compress magnetized plasmas.
