Minsk vs Aurora

Informations

Minsk (Belarusian: Мінск/Менск [mʲinsk], Russian: Минск) is the capital and the largest city of Belarus, located on the Svislač and the Niamiha rivers. As the capital, Minsk has a special administrative status in Belarus and is the administrative centre of Minsk Region (voblasć) and Minsk District (rajon). As of January 2018, its population was 1,982,444, (not including suburbs), making Minsk the 11th most populous city in Europe. Minsk is the administrative capital of the Commonwealth of Independent States (CIS) and seat of its Executive Secretary. The earliest historical references to Minsk date to the 11th century (1067), when it was noted as a provincial city within the Principality of Polotsk.

The settlement developed on the rivers. In 1242, Minsk became part of the Grand Duchy of Lithuania. It received town privileges in 1499.From 1569, it was a capital of the Minsk Voivodeship, in the Polish–Lithuanian Commonwealth. It was part of a region annexed by the Russian Empire in 1793, as a consequence of the Second Partition of Poland. From 1919 to 1991, after the Russian Revolution, Minsk was the capital of the Byelorussian Soviet Socialist Republic, in the Soviet Union. In June 2019, Minsk hosted the 2019 European Games.

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.
