A new special collection invites papers pertaining to the use of machine learning techniques in all sub-fields of heliophysics.
Scientists have traced past pathways of tectonic plates back a billion years using computer models, with intriguing results. Incorporating geologic data as a check on model output, however, has proven tricky.
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.
Magnetometers detected faint signals that with further study, may improve our understanding of what happens before earthquakes and offer promise for early detection.
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.
The Paleocene-Eocene Thermal Maximum, a thermal pulse about 56 million years ago, is an analog for future global warming. A new magnetofossil study shows progressive ocean deoxygenation.
Helioseismology allows scientists to study the interior of the Sun, solve some basic physics mysteries, and forecast space weather.
Each solar cycle might seem like the same old story, but one thing has changed significantly since the previous solar maximum–our technology.
The magnetic record stored in rocks documents the liquid core’s behavior and possibly when the inner core formed. Whether it formed half a billion or more than a billion years ago, however, is up for debate.
The loss cone of energetic particles in the Earth’s inner magnetosphere is substantially modified during disturbed times, with important implications for the radiation-belt and ring current modeling.
