Aurora vs Tashkent

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.

Tashkent (; Russian pronunciation: [tɐʂˈkʲent]; Russian: Ташкент, tr. Tashkent), or Toshkent (Uzbek pronunciation: [tɒʃˈkent]; Uzbek: Toshkent, Тошкент, تاشكینت‎), is the capital and largest city of Uzbekistan, as well as the most populous city in ex-Soviet Central Asia, with a population in 2018 of 2,485,900. It is in northeastern Uzbekistan, near the border with Kazakhstan. Before Islamic influence started in the mid 8th century AD, Tashkent was influenced by the Sogdian and Turkic cultures. After Genghis Khan destroyed it in 1219, it was rebuilt and profited from the Silk Road. From the 18th to the 19th century, the city became an independent city-state, before being re-conquered by the Khanate of Kokand.

In 1865, Tashkent fell to the Russian Empire, and became the capital of Russian Turkestan. In Soviet times, it witnessed major growth and demographic changes due to forced deportations from throughout the Soviet Union. Much of Tashkent was destroyed in the 1966 Tashkent earthquake, but it was rebuilt as a model Soviet city. It was the fourth-largest city in the Soviet Union at the time, after Moscow, Leningrad and Kyiv. Today, as the capital of an independent Uzbekistan, Tashkent retains a multiethnic population, with ethnic Uzbeks as the majority. In 2009, it celebrated its 2,200 years of written history.
