Aurora vs Oldham

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.

Oldham is a large town in Greater Manchester, England, amid the Pennines and between the rivers Irk and Medlock, 5.3 miles (8.5 km) southeast of Rochdale and 6.9 miles (11.1 km) northeast of Manchester. It is the administrative centre of the Metropolitan Borough of Oldham, which had a population of 230,800 in 2015. Historically in Lancashire, and with little early history to speak of, Oldham rose to prominence in the 19th century as an international centre of textile manufacture. It was a boomtown of the Industrial Revolution, and among the first ever industrialised towns, rapidly becoming "one of the most important centres of cotton and textile industries in England". At its zenith, it was the most productive cotton spinning mill town in the world, producing more cotton than France and Germany combined.

Oldham's textile industry fell into decline in the mid-20th century; the town's last mill closed in 1998. The demise of textile processing in Oldham depressed and heavily affected the local economy. Today Oldham is a predominantly residential town, and the improvement of the town centre is the focus of a project for transforming Oldham into a centre for further education and the performing arts. It is, however, still distinguished architecturally by the surviving cotton mills and other buildings associated with that industry. As of 2001, the town had a population of 103,544 and an area of around 26 square miles (67 km2).
