Aurora vs Wilkes-Barre

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.

Wilkes-Barre ( or ) is a city in the U.S. state of Pennsylvania and the county seat of Luzerne County. Located at the center of the Wyoming Valley, it had an estimated population of 40,766 in 2019. It is the second-largest city (after Scranton) of the Scranton–Wilkes-Barre–Hazleton, PA Metropolitan Statistical Area, which had a population of 563,631 as of the 2010 Census and is the fourth-largest metropolitan area in Pennsylvania. Wilkes-Barre and the surrounding Wyoming Valley are framed by the Pocono Mountains to the east, the Endless Mountains to the north and west, and the Lehigh Valley to the south. The Susquehanna River flows through the center of the valley and defines the northwestern border of the city. Wilkes-Barre was founded in 1769 and formally incorporated in 1806.

The city grew rapidly in the 19th century after the discovery of nearby coal reserves and the arrival of hundreds of thousands of immigrants who provided a labor force for the local mines. The coal mining fueled industrialization in the city, which reached the height of its prosperity in the first half of the 20th century. Its population peaked at more than 86,000 in 1930. Following World War II, the city's economy declined due to the collapse of industry. The Knox Mine disaster accelerated this trend after large portions of the area's coal mines were flooded and could not be reopened. Today, the city has around half of its peak population of the 1930s, making it the largest city in Luzerne County and the 13th-largest city in Pennsylvania.
