The Solar Wind


When the solar wind reaches Earth, only a small percentage of the windís energy penetrates Earthís magnetic field. But the energy that does enter is enough to create the brilliant aurora around Earthís poles and to endanger many of our high technology systems.

The solar wind pushes and stretches Earthís magnetic field into a vast, comet-shaped region called the magnetosphere. The magnetosphere and Earthís atmosphere protect us from the solar wind and other solar and cosmic radiation.
