Newcastle upon Tyne vs Aurora

Informations

Newcastle upon Tyne (, locally (listen)), often shortened to simply Newcastle, is a city in Tyne and Wear. On the northern bank of the River Tyne, it is 8.5 mi (13.7 km) from the North Sea. Newcastle is the most-populous city in North East England and forms the core of the Tyneside conurbation, the eighth most populous urban area in the United Kingdom. It is a member of the UK Core Cities Group, as well as the Eurocities network of European cities. It was part of the county of Northumberland until 1400, when it became a county of itself, a status it retained until becoming part of Tyne and Wear in 1974. Newcastle is a part of the North of Tyne Combined Authority. The regional nickname and dialect for people from Newcastle and the surrounding area is Geordie. The city developed around the Roman settlement Pons Aelius and was named after the castle built in 1080 by William the Conqueror's eldest son Robert Curthose.

In the 14th century, the city grew as an important centre for the wool trade and later became a major coal mining area. The port developed in the 16th century and, along with the shipyards lower down the River Tyne, was amongst the world's largest ship-building and ship-repairing centres.Newcastle's economy includes corporate headquarters, learning, digital technology, retail, tourism, and cultural centres, from which the city contributes £13 billion towards the United Kingdom's GVA. Among its icons are Newcastle United FC and the Tyne Bridge. Since 1981, the city has hosted the Great North Run, a half marathon which attracts over 57,000 runners each year.

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.
