climate change -- is it real? How much, if any, is being caused
by the Sun? Who will be most affected by future problems caused
by rising seas, growing deserts, and more frequent droughts?

your high school like to monitor solar storms? High above us lies
a desolate place where continual blasts of particles and energy
from the Sun pound the top of Earth's atmosphere. This "ionized"
region, where electrons and nuclei dart around freely, is a plasma
we call the ionosphere. The ionosphere reacts strongly to the intense
x-ray and ultraviolet radiation released by the Sun during a solar
flare or solar storm. We can track these solar disturbances by monitoring
changes to the Earth's ionosphere. The Solar Center has a project
to place ionospheric monitors in high schools and community colleges
around the world.
out Space Weather
In 1609, Galileo first pointed his homemade telescope toward the
heavens. Over the next several years he would discover sunspots, the
moons of Jupiter, the "seas" and craters on the Moon, and the phases of
Venus, and in the words of Albert Einstein, he would become "the father
of modern science". This page contains a short biography, links, and
activities related to Galileo's discoveries.
