Aurora vs Stirling

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.

Stirling (; Scots: Stirlin; Scottish Gaelic: Sruighlea [ˈs̪t̪ɾuʝlə]) is a city in central Scotland, 26 miles (42 km) north-east of Glasgow and 37 miles (60 km) north-west of the Scottish capital, Edinburgh. The market town, surrounded by rich farmland, grew up connecting the royal citadel, the medieval old town with its merchants and tradesmen, the Old Bridge and the port. Located on the River Forth, Stirling is the administrative centre for the Stirling council area, and is traditionally the county town of Stirlingshire. Proverbially it is the strategically important "Gateway to the Highlands". It has been said that "Stirling, like a huge brooch clasps Highlands and Lowlands together". Similarly "he who holds Stirling, holds Scotland" is often quoted. Stirling's key position as the lowest bridging point of the River Forth before it broadens towards the Firth of Forth made it a focal point for travel north or south.When Stirling was temporarily under Anglo-Saxon sway, according to a 9th-century legend, it was attacked by Danish invaders. The sound of a wolf roused a sentry, however, who alerted his garrison, which forced a Viking retreat. This led to the wolf being adopted as a symbol of the town as is shown on the 1511 Stirling Jug.

The area is today known as Wolfcraig.Even today the wolf appears with a goshawk on the council's coat of arms along with the recently chosen motto: "Steadfast as the Rock".Once the capital of Scotland, Stirling is visually dominated by Stirling Castle. Stirling also has a medieval parish church, the Church of the Holy Rude, where, on 29 July 1567, the infant James VI was anointed King of Scots by Adam Bothwell, the Bishop of Orkney, with the service concluding after a sermon by John Knox. The poet King was educated by George Buchanan and grew up in Stirling. He was later also crowned King of England and Ireland on 25 July 1603, bringing closer the countries of the United Kingdom. Modern Stirling is a centre for local government, higher education, tourism, retail, and industry. The mid-2012 census estimate for the population of the city is 36,440; the wider Stirling council area has a population of about 93,750.One of the principal royal strongholds of the Kingdom of Scotland, Stirling was created a royal burgh by King David I in 1130. In 2002, as part of Queen Elizabeth's Golden Jubilee, Stirling was granted city status.
