Aurora vs Lubeck

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.

Lübeck ( LOO-bek, German: [ˈlyːbɛk] (listen); Low German also: Lübeek; Danish: Lybæk), officially the Hanseatic City of Lübeck (German: Hansestadt Lübeck), is, with around 217,000 inhabitants, the second-largest city on the German Baltic coast and in the state of Schleswig-Holstein, after its capital of Kiel, and it is the 35th-largest city in Germany. The city lies in Holstein, northeast of Hamburg, on the mouth of the River Trave, which flows into the Bay of Lübeck in the borough of Travemünde, and on the Trave's tributary Wakenitz. The Elbe–Lübeck Canal, which connects the Baltic to the Elbe River at Lauenburg, also crosses the city. Lübeck is surrounded by the lakes of the Lauenburg Lakes Nature Park in the southeast, and the lakes of Wagria in the northwest. The city is part of the Hamburg Metropolitan Region, and is the southwesternmost city on the Baltic, as well as the closest point of access to the Baltic from Hamburg. The port of Lübeck is the second-largest German Baltic port after the port of Rostock. There is a regional airport in the southern borough of Blankensee.

The city lies in the Northern Low Saxon dialect area of Low German. Lübeck had once been founded as the Slavic village Liubice, and its name is of Slavic origin. The city is famous for having been the cradle and the de facto capital of the Hanseatic League. Its city centre is Germany's most extensive UNESCO World Heritage Site. While the city's symbol is the Holsten Gate, Lübeck's skyline is dominated by the seven towers of its five main churches St Mary's, Lübeck Cathedral, St Jacob's, St Peter's, and St Giles'. The cathedral, finished around 1230, was the first large brickwork church in the Baltic region. St Mary's, finished in 1351, served as model for the other Brick Gothic churches around the Baltic. It has the second-tallest two-steeples façade after Cologne Cathedral, which only surpassed it in 1880, the tallest brick vault, and is the second-tallest brickwork structure after St Martin's in Landshut. Travemünde is a famous seaside resort, and its Maritim high-rise serves as the second-tallest lighthouse in the world at 114 metres high. Lübeck is also known for Lübeck Marzipan.
