Postmidnight flows appear to be triggered by the same mechanism that drives more frequently observed evening flows.
Energetic collisions between magnetic fields produce gusty solar wind.
Infrared observations reveal that Jupiter’s upper atmosphere is much warmer than models predict. The discovery may be a clue to finding missing heat sources in other giant planets.
Though not as damaging as extreme space weather events, showers of plasma jets hit Earth’s magnetic shield every day—yet we’re only beginning to understand their effects.
Each solar cycle might seem like the same old story, but one thing has changed significantly since the previous solar maximum–our technology.
A new study supports the idea of a “helicity barrier” influencing the fluctuating stream of interplanetary plasma.
MESSENGER observations show a 50% rise in atmospheric sodium-group ions during periods of high solar wind activity.
Updated procedures enable consistent use of a wide network of polar magnetometers to monitor energy flow into the tail of Earth’s magnetosphere during the growth phase of substorms.
Solar wind plasma data captured by the Tianwen-1 probe while in transit to Mars represent an important step toward a new era of cooperative Martian space exploration.
Charged particles escape our atmosphere following Earth’s magnetic field and constitute a main source of matter that modulates Sun-Earth interactions.
