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).

Pristina (UK: , US: , Albanian pronunciation: [pɾiʃˈtinə] (listen); Albanian: Prishtina or Prishtinë, Serbian: Приштина / Priština) is the capital of Kosovo and the seat of the eponymous municipality and district. Its population is predominantly Albanian-speaking constituting the second-largest such city in Europe, after Tirana. The city is located in the northeastern section of Kosovo in a relatively flat plain close to the Gollak mountains.
During the Paleolithic Age, what is now the area of Pristina was involved by the Vinča culture. It was home to several Illyrian and Roman people at the classical times. King Bardyllis brought various tribes together in the area of Pristina in the 4th century BC, establishing the Dardanian Kingdom. The heritage of the classical era is still evident in the city, represented by ancient city of Ulpiana, that was considered one of the most important Roman cities in the Balkan peninsula. Between the 5th and the 9th century the area was part of the Byzantine Empire. In the middle of the 9th century it was ceded to the First Bulgarian Empire. In the early 11th century it fell under Byzantine rule and was included into a new province called Bulgaria. Between the late 11th and middle of the 13th century it was ceded several times to the Second Bulgarian Empire.
