Tides Ripple Across Earth’s Plasma “Donut”
Interactions between lunar gravity and the terrestrial magnetic field may cause a 90° offset from the Moon’s position in its orbit.
Machine Learning Helps to Solve Problems in Heliophysics
A new special collection invites papers pertaining to the use of machine learning techniques in all sub-fields of heliophysics.
Converging Toward Solutions to Grand Challenges
A hypothetical, space weather–induced power grid catastrophe served as a practice case for building unity and collaborative skills among disparate communities to address a major global hazard.
Space Raindrops Splashing on Earth’s Magnetic Umbrella
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.
Origin of Dawnside Subauroral Plasma Flows in Geomagnetic Storms￼
Geomagnetic storms induce fast plasma flows next to the aurora and affect space weather. Lin et al. explain the origin of a special “dawnside” plasma stream that occurs only during extreme storm events.
Shake, Rattle, and Probe
Helioseismology allows scientists to study the interior of the Sun, solve some basic physics mysteries, and forecast space weather.
11 Discoveries Awaiting Us at Solar Max
Each solar cycle might seem like the same old story, but one thing has changed significantly since the previous solar maximum–our technology.
Uncovering the Mysterious STEVE Aurora
Scientists present the first direct observations on the rapid evolution of a bright red auroral arc into a thin white-mauve arc known as STEVE.
Watching the Substorms Grow
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.
