Solar physicists say they have found a key source of intense gamma rays unleashed when Earth's nearest star produces its most ...

By tracing solar flare gamma rays, scientists gain new insight into particle behavior that shapes space weather forecasts.

Space weather observers warn that the Van Allen radiation belts are now fully charged after repeated solar storms, raising ...

At times, the sun ejects energetic material into space, which can have consequences for space-based and even ground-based ...

Solar energetic particle (SEP) events and coronal mass ejections (CMEs) are central features of solar activity that significantly influence space weather. SEPs are high‐energy particles expelled ...

Solar Orbiter has identified the Sun’s dual “engines” for superfast electrons: explosive flares and sweeping coronal mass ejections. By catching over 300 events close to their origin, the mission has ...

Commonly seen velocity dispersion feature is marked with blue circles in lower energy range observed by Solar Orbiter, while the onset of inverse velocity particles is indicated with orange triangles ...

A complete survey of all the particle and antiparticle activity that goes on during the Sun’s 11-year cycle has found previously unknown ways these particles behave. Cosmic rays coming from outside ...
