Winchester vs Aurora

Informations

Winchester is a cathedral city in Hampshire, England. The city lies at the heart of the wider City of Winchester, a local government district, at the western end of the South Downs National Park, on the River Itchen. It is 60 miles (97 km) south-west of London and 14 miles (23 km) from Southampton, the closest other city. At the 2011 census, Winchester had a population of 45,184. The wider City of Winchester district, which includes towns such as Alresford and Bishop's Waltham, has a population of 116,595. Winchester is the county town of Hampshire and contains the head offices of Hampshire County Council.

Winchester was the first and former capital city of England. It developed from the Roman town of Venta Belgarum, which in turn developed from an Iron Age oppidum. Winchester remained the most important city in England until the Norman conquest in the eleventh century. The city has since become one of the most expensive and affluent areas in the United Kingdom. The city's major landmark is Winchester Cathedral. The city is also home to the University of Winchester and Winchester College, the oldest public school in the United Kingdom still using its original buildings.

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.
