(001) 11-30-2007 (TransAlaska Pipeline in foreground) Aurora Borealis are natural different colored light displays, usually observed in the night sky over the earths polar regions. In the northern latitudes they are known as the Aurora Borealis, named after the Roman Goddess 'Aurora' and the Greek word for wind 'Boreas.' Since they are only visible in the North sky, they are also known as the 'Northern Lights.' They often appear as a greenish glow, and sometimes a faint red. They are constantly in motion because of the changing interaction between the solar wind and the earths magnetic field. The sun gives off high energy charged particles (ions) that travel out into space at speeds of 300 to 1200 kilometers per second (this cloud of particles is called a plasma). The stream of plasma coming from the sun is known as the solar wind. As the solar wind interacts with the edge of the earths magnetic field, some of the particles become trapped and they follow the lines of magnetic force down into the ionosphere (ionosphere is the section of the earths atmosphere that extends above the earths surface). When the trapped particles collide with the gases in the ionosphere they start to glow, producing the spectacle that is known as the Auroras.
