Physics of Space Weather

Subatomic particles zipping around through magnetized plasma - does that sound like physics to you? The tools of the science of physics are essential ingredients for an understanding of space weather phenomena. This page provides links to physics fundamentals relevant to space weather.
This is an artist's conception of the Earth and the inner and outer <a href="/glossary/radiation_belts.html&edu=high&dev=">radiation belts</a> that surround it. The Earth's radiation belts are just one part of the system called the <a href="/earth/Magnetosphere/overview.html&edu=high&dev=">magnetosphere</a>. The radiation belts of the Earth are made up of <a href="/physical_science/physics/atom_particle/electron.html&edu=high&dev=">electrons</a>, <a href="/physical_science/physics/atom_particle/proton.html&edu=high&dev=">protons</a> and heavier atomic ions. These particles get trapped in the <a href="/earth/Magnetosphere/earth_magnetic_field.html&edu=high&dev=">magnetic field of the Earth</a>. These belts were <a href="/earth/Magnetosphere/radiation_belts_discovery.html&edu=high&dev=">discovered</a> by James Van Allen in 1958, and so they are known as Van Allen Belts.<p><small><em>Courtesy of Windows to the Universe</em></small></p>

Extended Period of Lower Solar Activity Linked to Changes in Sun's Conveyor Belt

A new analysis of the unusually long solar cycle that ended in 2008 suggests that one reason for the long cycle could be a stretching of the sun's conveyor belt, a current of plasma that circulates between...Read more
