A large, eruptive prominence extends more than 35 Earth diameters above the surface of the Sun in July 1999. Viewed here in ultraviolet light by SOHO, prominences are dense clouds of plasma trapped in the Sun's magnetic field.

The blue paths emanating from the Earth's poles represent some of its magnetic field lines, which deflect most of the energy and plasma of the CME. (Not drawn to scale.)

On the lower right is a simulated auroral display in ultraviolet as viewed with the North Pole at the center. The region of magnetic field connected to Earth's North and South Poles is indicated by the comet-like surface.

Astronauts on space shuttle flight STS-39 shot this photo of the aurora australis, or southern lights, in May 1991. Auroras form along the edge of space, where high-energy particles trapped in our planet's magnetic field slam into the gases of the upper atmosphere.

In this case, the aurora has formed a rare "corona," a phenomenon where the center of the aurora appears directly overhead, radiating from a center point. Courtesy of Jan Curtis.
