Bringing Clarity to Magnetic Reconnection
A particle-level process appears to play a key role in planet-sized events throughout the universe.
New Insights from the Magnetic Properties of Fault Rocks
Magnetic studies offer a new strand for the analysis of faulting processes and could help with better understanding of fault rupture and earthquakes.
A Juno Era Model of the Jovian Magnetosphere
Updating a model developed during the Voyager flybys will enable better mission planning and a deeper understanding of Juno data.
Measuring Massive Magnetic Meteorites
A new tool to measure the magnetic signatures of big meteorites could not only aid NASA’s mission to Psyche; it could also help solve mysteries about how magnetic fields formed in our early solar system.
New Results Concerning Solar Wind Entry into the Magnetosphere
A new book describes recent results defining the many pathways and foreshock, bow shock, magnetosheath, and magnetopause phenomena connecting the solar wind to the dayside magnetosphere.
Geomagnetic Storms Probably Don’t Cause Mass Cetacean Strandings
Solar-induced geomagnetic activity and mass strandings of whales and dolphins on shorelines both show seasonal patterns, but the beachings likely result from multiple environmental factors.
Machine Learning for Magnetics
Classic interpretation of aeromagnetic anomaly maps involves several steps with limiting boundary conditions; a recent study develops convolutional networks largely bypassing these issues.
Unmixing Magnetic Components – An Experimental Twist
Various unmixing approaches are used in environmental magnetism, each starting from a different premise; now they are put to the test by scrutinizing experimental mixtures of known endmembers.
Terrestrial Radio Signals May Suppress High-Energy Electrons
Naval radio signals may cause the formation of a barrier observed during geomagnetic storms that is seemingly impenetrable by relativistic electrons.
