Related Topics: Earth, Solar Flares and Space Weather

The aurora borealis, also known as the northern lights, is the rippling night-sky light display found at the northernmost reaches of the Earth. The south has a corresponding aurora australis, also known as the southern lights. The northern and southern auroras occur when charged particles released by the sun, called the solar wind, are guided along the Earth's magnetic field to its poles and interact with particles in the upper atmosphere there.
