Nashville vs Aurora

Informations

Nashville is the capital and most populous city of the U.S. state of Tennessee. The city is the county seat of Davidson County and is located on the Cumberland River. It is the 23rd most-populous city in the United States. Named for Francis Nash, a general of the Continental Army during the American Revolutionary War, the city was founded in 1779. The city grew quickly due to its strategic location as a port on the Cumberland River and, in the 19th century, a railroad center. Nashville seceded with Tennessee during the American Civil War; in 1862 it was the first state capital in the Confederacy to fall to Union troops. After the war, the city reclaimed its position and developed a manufacturing base. Since 1963, Nashville has had a consolidated city-county government, which includes six smaller municipalities in a two-tier system. The city is governed by a mayor, a vice-mayor, and a 40-member metropolitan council; 35 of the members are elected from single-member districts, while the other five are elected at-large.

Reflecting the city's position in state government, Nashville is home to the Tennessee Supreme Court's courthouse for Middle Tennessee, one of the state's three divisions. A major center for the music industry, especially country music, Nashville is commonly known as "Music City". It is also home to numerous colleges and universities, including Tennessee State University, Vanderbilt University, Belmont University, Fisk University, Trevecca Nazarene University, and Lipscomb University, and is sometimes referred to as "Athens of the South" due to the large number of educational institutions. Nashville is also a major center for the healthcare, publishing, private prison, banking, automotive, and transportation industries. Entities with headquarters in the city include Asurion, Bridgestone Americas, Captain D's, CoreCivic, Dollar General, Hospital Corporation of America, LifeWay Christian Resources, Logan's Roadhouse, and Ryman Hospitality Properties.

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.
