Aurora vs Sylacauga

Informations

An aurora (plural: auroras or aurorae), sometimes referred to as polar lights (aurora polaris), northern lights (aurora borealis), or southern lights (aurora australis), is a natural light display in the Earth's sky, predominantly seen in high-latitude regions (around the Arctic and Antarctic). Auroras are the result of disturbances in the magnetosphere caused by solar wind. These disturbances are sometimes strong enough to alter the trajectories of charged particles in both solar wind and magnetospheric plasma. These particles, mainly electrons and protons, precipitate into the upper atmosphere (thermosphere/exosphere).

The resulting ionization and excitation of atmospheric constituents emit light of varying color and complexity. The form of the aurora, occurring within bands around both polar regions, is also dependent on the amount of acceleration imparted to the precipitating particles. Precipitating protons generally produce optical emissions as incident hydrogen atoms after gaining electrons from the atmosphere. Proton auroras are usually observed at lower latitudes.

Sylacauga is a city in Talladega County, Alabama, United States. At the 2010 census the population was 12,749.Nicknames for Sylacauga include "The Marble City", “The Cog”, and "Alabama’s Best-Kept Secret". Sylacauga is known for its fine white marble bedrock. This was discovered shortly after settlers moved into the area and has been quarried ever since. The marble industry was the first recorded industry in the Sylacauga area.

Sylacauga is the site of the first documented case of an object from outer space hitting a person. On November 30, 1954, a 4 kg (9 lb) piece of what became known as the Hodges Meteorite crashed through the roof of an Oak Grove house, bounced off a radio, and badly bruised Mrs. Ann Hodges, who was taking an afternoon nap. Sylacauga is on the 2010 list of "100 Best Communities for Young People" by America's Promise Alliance.
