Space Weather: Big and Small—A Continuous Risk

Artistic rendering of the Sun and its atmosphere consist
Friday, May 10, 2019

"Space Weather" is the term used to describe the relentless barrage of particles that bathe the Earth and other planetary bodies of the solar system that originate in the steady evolution, and catastrophic breakdown, of magnetic structures on the Sun.
