Solar Storms

The term 'Solar Storm' has become popular as a way to describe bursts of matter and energy from the sun. Some of these are solar flares, which produce explosions of electromagnetic energy traveling at the speed of light (x-rays etc). Other kinds of solar storms involve ejections of matter traveling at millions of miles per hour. Scientists call this patina of solar storminess 'Space Weather'. Space weather can cause all sorts of problems on Earth with our technology. For more information, visit the Human Impacts of Space Weather and Solar Storms website at www.solarstorms.org, for detailed discussions of these important consequences.
