...one of nasa's newest efforts is the living with a star (lws)
program. its focus, as the name implies, is developing a better
stellar sense of our star - the sun.

a key component of the lws effort is to explore the effects of solar
variability within the sun-earth system. the sun pumps out volumes of
high-energy particles and radiation, wafting through and affecting
the entire "geospace" region. although the earth is under a
protective shield of a magnetic field and atmosphere, the planet's
ionosphere and magnetosphere do react to solar fluctuations. much of
the sun's outpouring of energy reaches the surface of the earth.
