Magnetic Field Pulsations and Aurora Tightly Linked
Mysterious plasma waves from space are generating displays of aurora near Earth's poles.
Cassini Observes First Evidence of Saturn's Ionospheric Outflow
Evidence shows the ionosphere may contribute as much mass as the moon Enceladus.
Satellites Test Theory of Magnetic Reconnection
A quartet of satellites flying through Earth's magnetic field measures its interaction with the Sun's and puts a theory about their reconnection to the test.
How Saturn Alters the Ionosphere of Titan
New research shows that Saturn's powerful magnetic field changes the atmospheric chemistry of its largest moon, Titan.
Scientists Detect Wisps of Wind in Space
In the near vacuum of low-Earth orbit, there are still faint tendrils of air—but measuring them is very tricky. A new study comparing two methods will make it a little easier.
Decoding the Radio Transmissions of Shooting Stars
Spectacular fireball meteors don't just light up the night sky—recent observations show they also emit mysterious high-frequency radio waves. Now scientists think they understand why.
Electric "Tornadoes" in Space Drive Disturbances Down to Earth
New simulations show how shocks in space can trigger vortexes in Earth's magnetic field, causing magnetic disturbances that are detectable from the ground.
Mercury's Magnetosphere Model Gets Retro Makeover
New observations from Mercury revive a once-abandoned model for its magnetic field, resulting in a new profile that better fits the data.
What Makes Jupiter's Aurora Pulse?
The aurora crowning Jupiter's poles—the most powerful in the solar system—flares up when plasma is injected into its magnetic field.
