Aurora vs Tampere

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.

Tampere (, US also , Finnish: [ˈtɑmpere] (listen); Swedish: Tammerfors [tɑmːærˈforsː] (listen); Latin: Tammerforsia) is a city in Pirkanmaa in the western part of Finland. Tampere is the most populous inland city in the Nordic countries; it has a population of 238,140 with the urban area holding 334,112 people and the metropolitan area, also known as the Tampere sub-region, holding 385,301 inhabitants in an area of 4,970 km2 (1,920 sq mi). Tampere is the second-largest urban area and third most-populous individual municipality in Finland, after the cities of Helsinki and Espoo and the most populous Finnish city outside the Greater Helsinki area, within which both Helsinki and Espoo are located. Tampere is a major urban, economic, and cultural hub for central Finland.Tampere is wedged between two lakes, Näsijärvi and Pyhäjärvi. Since the two lakes differ in level by 18 metres (59 ft), the rapids linking them, Tammerkoski, have been an important power source throughout history, most recently for generating electricity. Tampere is dubbed the "Manchester of the North" for its industrial past as the former center of Finnish industry, and this has given rise to its Finnish nickname "Manse" and terms such as "Manserock".

Also, Tampere has been officially declared the "Sauna Capital of the World", because it has the most public saunas in the world.Helsinki is approximately 160 kilometres (100 mi) south of Tampere, and can be reached in 1 hr, 31 minutes by Pendolino high-speed rail service and 2 hours by car. The distance to Turku is roughly the same. Tampere–Pirkkala Airport is Finland's eighth-busiest airport, with over 230,000 passengers in 2017. Tampere also serves as an important transit route for three Finnish highways: Highway 3 (E12), Highway 9 (E63) and Highway 12. Tampere ranked 26th in the list of 446 cities in the world's hipster cities, and it has often been rated as the most popular city in Finland.By 2021, a new multi-purpose sports and entertainment center, Tampere Deck Arena, is nearing completion.
