Cieszyn vs Aurora

Informations

Cieszyn (Polish: [ˈtɕɛʂɨn] (listen); Czech: Těšín [ˈcɛʃiːn] (listen); German: Teschen; Latin: Tessin) is a border town in southern Poland on the east bank of the Olza River, and the administrative seat of Cieszyn County, Silesian Voivodeship. The town has 34,513 inhabitants (as of 2019), and lies opposite Český Těšín in the Czech Republic's Karviná District, Moravian-Silesian Region.

Both towns belonged to the historical region of Austrian Silesia and formerly as one town composed the capital of the region of Cieszyn Silesia.

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.
