Using a combination of independent models and observations over multiple timescales, scientists verify two important models that gauge the amount of solar radiation Earth receives.Read More »Space Science & Space Physics
A first usage of principal component analysis on Hubble images of Jupiter’s auroral ovals reveals the most common patterns, and machine learning classification reveals their physical causes.Read More »Space Science & Space Physics
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 »
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 »
