Heliophysics

Space is not, as is often believed, completely empty; instead, we live in the extended atmosphere of an active star. Our Sun sends out a steady outpouring of particles and energy -- the solar wind – as well as a constantly writhing magnetic system. This extensive, dynamic solar atmosphere surrounds the Sun, Earth, the planets, and extends far out into the solar system.

Heliophysics is a Roadmap to understanding the environment of our Earth, from its life-sustaining Sun out past the frontiers of the solar system.
