Aurora vs Anchorage

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.

Anchorage (officially called the Municipality of Anchorage; Dena'ina: Dgheyay Kaq'; Russian: Анкоридж) is a unified municipal consolidated city-borough in the U.S. state of Alaska, on the West Coast of the United States. With an estimated 288,000 residents in 2019, it is Alaska's most populous city and contains nearly 40% of the state's population; among the 50 states, only New York has a higher percentage of residents who live in its most populous city. The Anchorage metropolitan area, which includes Anchorage and the neighboring Matanuska-Susitna Borough, had a population of 396,317 in 2019, accounting for more than half the state's population. At 1,706 square miles (4,420 km2) of land area, the city is the fourth-largest by area in the United States and larger than the smallest state, Rhode Island, which has 1,212 square miles (3,140 km2).Anchorage is in Southcentral Alaska, at the terminus of the Cook Inlet, on a peninsula formed by the Knik Arm to the north and the Turnagain Arm to the south.

The city limits span 1,961.1 square miles (5,079.2 km2), encompassing the urban core, a joint military base, several outlying communities and almost all of Chugach State Park.Due to its location, almost equidistant from New York City and Tokyo, Anchorage lies within ​9 1⁄2 hours by air of nearly 90% of the industrialized world. For this reason, Ted Stevens Anchorage International Airport is a common refueling stop for international cargo flights and home to a major FedEx hub, which the company calls a "critical part" of its global network of services.Anchorage has won the All-America City Award four times: in 1956, 1965, 1984–85, and 2002, from the National Civic League. Kiplinger has named it the United States' most tax-friendly city.
