Bolton vs Aurora

Informations

Bolton ( (listen), locally ) is a large town in Greater Manchester in North West England, historically and traditionally a part of Lancashire. A former mill town, Bolton has been a production centre for textiles since Flemish weavers settled in the area in the 14th century, introducing a wool and cotton-weaving tradition. The urbanisation and development of the town largely coincided with the introduction of textile manufacture during the Industrial Revolution. Bolton was a 19th-century boomtown and, at its zenith in 1929, its 216 cotton mills and 26 bleaching and dyeing works made it one of the largest and most productive centres of cotton spinning in the world. The British cotton industry declined sharply after the First World War and, by the 1980s, cotton manufacture had virtually ceased in Bolton. Close to the West Pennine Moors, Bolton is 10 miles (16 km) north-west of Manchester. It is surrounded by several smaller towns and villages that together form the Metropolitan Borough of Bolton, of which Bolton is the administrative centre.

The town of Bolton has a population of 139,403, whilst the wider metropolitan borough has a population of 262,400. Bolton originated as a small settlement in the moorland known as Bolton le Moors. In the English Civil War, the town was a Parliamentarian outpost in a staunchly Royalist region and, as a result, was stormed by 3,000 Royalist troops led by Prince Rupert of the Rhine in 1644. In what became known as the Bolton Massacre, 1,600 residents were killed and 700 were taken prisoner. Bolton Wanderers football club play home games at the University of Bolton Stadium and the WBA World light-welterweight champion Amir Khan was born in the town. Cultural interests include the Octagon Theatre and the Bolton Museum and Art Gallery, as well as one of the earliest public libraries established after the Public Libraries Act 1850.

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.
