Light show in the Sky
People who live far enough north or far enough south often see a light show called an aurora on clear nights. Great sheets of colourful light seem to ripple in the sky like curtains swaying in a breeze.
This light show takes place in Earth’s atmosphere, but it is caused by the sun. The sun shoots particles of matter into space. Many of these particles come to Earth. Near Earth’s North and South poles are two points that act like giant magnets. These points are called the north and south magnetic poles. These two magnets attract the particles of energy from the sun. When these particles collide with other particles in Earth’s atmosphere, they glow. They fill the sky with shimmering light.
