A pioneering space plasma physicist who led the way in understanding how complex wave-particle interactions control Earth’s radiation belts and low-level auroral light emissions.Read More »Planetary Sciences
Aurorae once classified by human eyes are now being sorted by machines. The change may help astronomers understand how the mysterious features are powered.Read More »Planetary Sciences
Electrons energized and trapped at Mars were thought to lose energy inside the planet’s magnetosheath, but new research suggests a different explanation of spacecraft data.Read More »Mathematical Geophysics
The same algorithms that help control self-driving cars and speech-to-text functionality have helped build a virtual instrument to study the Sun.Read More »Space Science & Space Physics
The appearance of sunspots—their number, duration, and location—suggests that the dynamics of the Sun’s outer layer is synchronized with an internal clock.Read More »
A new book brings together insights from the space weather, geophysics, and power engineering communities to understand the characteristics and impacts of geomagnetically induced currents.Read More »Space Science & Space Physics
The first in situ measurement of the pressure at the edge of the solar system reveals that there’s still a lot we don’t know about what sets the size of the heliosphere.Read More »Space Science & Space Physics
Experiments at Sun-like temperatures show that certain elements absorb more light than solar models predict, creating uncertainties for stellar science.Read More »Space Science & Space Physics
Under a new mandate, consortia of the world’s major space weather centers will disseminate new space-weather advisories for civil aviators representing a significant change-of-state for space weather.Read More »
