What Surprises do the Icy Uranian Moons Hold?
With efforts ramping up to send a spacecraft back to the Uranian system, anticipation is increasing as to what geological surprises are hiding inside and on the surfaces of the icy Uranian moons.
Large Geomagnetic Field Changes Recorded by Archeomagnetism
A rare case of absolute paleointensity data in sub-centennial resolution from an archeological site provide much higher values than predicted by existing magnetic field models.
Baked Contacts Focus a Lens on Ancient Lava Flows
Two studies, conducted 40 years apart, show how combining field observations and thermal modeling can reconstruct the history of massive lava flows and how they altered the surrounding landscape.
Marine Science Goes to Space
Space and ocean scientists take a splash course in multidisciplinary science to chart our solar system’s ocean worlds.
Could Jupiter’s Heat Waves Help Solve a Planetary Energy Crisis?
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.
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.
Billion-Year Rewind Tracks Supercontinents and Mantle Structures
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.
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.
Slight Shifts in Magnetic Field Preceded California Earthquakes
Magnetometers detected faint signals that with further study, may improve our understanding of what happens before earthquakes and offer promise for early detection.
