Energetic electrons are accelerated directly by magnetic reconnections and can act as tracers of large-scale magnetic field conditions.
A new analysis of spacecraft data collected near the tip of Earth’s magnetotail sheds light on how geomagnetic activity affects the motion of electrons in this region.
Pipeline corrosion is an example of why we need better awareness of how long-term exposure to moderate space weather may have significant economic impact by slowly degrading vulnerable systems.
Both simulations and observations are used to measure the magnetic reconnection rate in the Earth’s magnetotail, suggesting that the rate is correlated with the intensity of a magnetic substorm.
This prolific researcher helped us understand the interactions of the solar wind and coronal mass ejections with Earth’s magnetic field.
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.
A new study proposes a simpler theory to explain a class of electrons zipping around Earth, propelled by magnetic explosions.
When the Earth's and the Sun's magnetic fields meet, they realign in explosive and mysterious reconnections. Data suggest that plasma waves called kinetic Alfvén waves play a key role.
NASA Magnetospheric Multiscale (MMS) mission detects energy differences in electrons scattered by magnetic reconnection.
