Nuremberg vs Aurora

Informations

Nuremberg ( NEWR-əm-burg; German: Nürnberg [ˈnʏʁnbɛʁk] (listen); in the local East Franconian dialect: Närmberch) is the second-largest city of the German federal state of Bavaria after its capital Munich, and its 511,628 (2016) inhabitants make it the 14th-largest city in Germany. On the Pegnitz River (from its confluence with the Rednitz in Fürth onwards: Regnitz, a tributary of the River Main) and the Rhine–Main–Danube Canal, it lies in the Bavarian administrative region of Middle Franconia, and is the largest city and the unofficial capital of Franconia. Nuremberg forms a continuous conurbation with the neighbouring cities of Fürth, Erlangen and Schwabach with a total population of 798,867 (2018), while the larger Nuremberg Metropolitan Region has approximately 3.6 million inhabitants. The city lies about 170 kilometres (110 mi) north of Munich. It is the largest city in the East Franconian dialect area (colloquially: "Franconian"; German: Fränkisch), Nuremberg was one of the host cities of the 2006 FIFA World Cup. There are many institutions of higher education in the city, including the University of Erlangen-Nuremberg (Friedrich-Alexander-Universität Erlangen-Nürnberg).

With 39,780 students in 2017, it is Bavaria's third-largest and Germany's 11th-largest university, with campuses in Erlangen and Nuremberg and a university hospital in Erlangen (Universitätsklinikum Erlangen). Technische Hochschule Nürnberg Georg Simon Ohm and Hochschule für Musik Nürnberg are also located within the city. Nuremberg Airport (Flughafen Nürnberg “Albrecht Dürer“) is the second-busiest airport in Bavaria after Munich Airport, and the tenth-busiest airport in Germany. Staatstheater Nürnberg is one of the five Bavarian state theatres, showing operas, operettas, musicals, and ballets (main venue: Nuremberg Opera House), plays (main venue: Schauspielhaus Nürnberg), as well as concerts (main venue: Meistersingerhalle). Its orchestra, Staatsphilharmonie Nürnberg, is Bavaria's second-largest opera orchestra after the Bavarian State Opera's Bavarian State Orchestra in Munich. Nuremberg is the birthplace of Albrecht Dürer and Johann Pachelbel. Nuremberg was the site of major Nazi rallies, and it provided the site for the Nuremberg trials, which held to account many major Nazi officials.

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.
