Aurora vs Chattanooga

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.

Chattanooga is a city in and the county seat of Hamilton County, Tennessee, along the Tennessee River bordering Georgia. With an estimated population of 182,799 in 2019, it is the fourth-largest city in Tennessee and one of the two principal cities of East Tennessee, along with Knoxville. The city anchors the Chattanooga metropolitan area, the fourth largest metropolitan statistical area in Tennessee, as well as a larger three-state area that includes Southeast Tennessee, Northwest Georgia, and Northeast Alabama. Served by multiple railroads and Interstate highways, Chattanooga is a transit hub. Chattanooga lies 118 miles (190 km) northwest of Atlanta, Georgia, 112 miles (180 km) southwest of Knoxville, Tennessee, 134 miles (216 km) southeast of Nashville, Tennessee, 102 miles (164 km) east-northeast of Huntsville, Alabama, and 147 miles (237 km) northeast of Birmingham, Alabama. Chattanooga was a crucial city during the American Civil War, due to the multiple railroads in the city. After the war, the railroads allowed for the city to grow into one of the largest heavy industrial hubs in the Southeastern United States.

Today, major industry that drives the economy includes automotive, advanced manufacturing, food and beverage production, healthcare, insurance, tourism, and back office and corporate headquarters.The city, with a downtown elevation of about 680 feet (210 m), is at the transition between the ridge-and-valley portion of the Appalachian Mountains and the Cumberland Plateau. Its official nickname is "Scenic City", alluding to the surrounding by mountains and ridges. Unofficial nicknames include "River City", "Chatt", "Nooga", "Chattown", and "Gig City", the latter a reference to Chattanooga's claims that it has the fastest internet service in the Western Hemisphere.Chattanooga is internationally known for the 1941 song "Chattanooga Choo Choo" by Glenn Miller and his orchestra. Chattanooga is home to the University of Tennessee at Chattanooga (UTC) and Chattanooga State Community College.
