Sometimes the conditions in the solar wind can change dramatically over short distances. Satellite observations of these features show that they’re more complex than previously thought.

Data Mining Reveals the Dynamics of Auroral Substorms
An analysis of 5 decades of satellite data has pieced together the most comprehensive picture yet of substorms, the magnetic disturbances that cause surges of aurora.
No Underground Magma Ocean on Jupiter’s Fiery Moon?
A new study suggests alternative explanations for Io’s unusual magnetic field.
Bringing Clarity to What Drives Auroras
A new classification scheme helps researchers distinguish what accelerates the electrons that create auroras.
The Accidental Particle Accelerator Orbiting Mars
The radar aboard the Mars Express spacecraft can generate ion beams arcing through space above the planet, which could lead to a new way of studying the plasma surrounding it.
What Drives Temperature Inversions in the Mesosphere?
A study of nightglow over India reveals that gravity waves are less important than previously thought.
Probing the Origin of a New Celestial Phenomenon
The first statistical study of STEVE events suggests that the appearance of these narrow ribbons of light is closely correlated with violent disturbances in Earth’s magnetosphere.
Plasma Density Distribution in Mercury’s Magnetosphere
A new measurement of plasma density distribution in Mercury’s magnetosphere obtained from observations of field line resonance events provides necessary constraint for many planetary science issues.
Windy Weather in the Thermosphere
The weather in the thermosphere includes winds that buffet spacecraft as they orbit the Earth, but how well can these winds be modeled?
Jupiter’s Stressed Out Magnetosphere Causes Aurora and Heating
Force imbalance between Jupiter’s ionosphere and magnetosphere leads to wave generation to release this stress, but the waves also accelerate particles, causing aurora and heating.
