Auroras: Splendors in the Sky
Cascades of color decorate the night sky with shifting, shimmering arcs, curtains, and rays. The light shows are eerily beautiful, and silent. They occur almost nightly in the high latitudes. The aurora borealis, or northern lights, can be seen from time to time over much of Europe and North America. About once every 10 years, skywatchers as far south as Cuba see it. The aurora australis, in the Southern Hemisphere, has been seen as far north as Singapore.
Most auroras occur between 100 and 320 kilometers (60 and 200 mi) above the earth. Auroras are caused by the solar wind. The solar wind is a stream of high-speed electrically ...
