Vega vs Stuttgart

Informations

Vega is the brightest star in the northern constellation of Lyra. It has the Bayer designation α Lyrae, which is Latinised to Alpha Lyrae and abbreviated Alpha Lyr or α Lyr. This star is relatively close at only 25 light-years from the Sun, and, together with Arcturus and Sirius, one of the most luminous stars in the Sun's neighborhood. It is the fifth-brightest star in the night sky, and the second-brightest star in the northern celestial hemisphere, after Arcturus. Vega has been extensively studied by astronomers, leading it to be termed "arguably the next most important star in the sky after the Sun". Vega was the northern pole star around 12,000 BC and will be so again around the year 13,727, when its declination will be +86° 14′. Vega was the first star other than the Sun to be photographed and the first to have its spectrum recorded. It was one of the first stars whose distance was estimated through parallax measurements. Vega has functioned as the baseline for calibrating the photometric brightness scale and was one of the stars used to define the zero point for the UBV photometric system.

Vega is only about a tenth of the age of the Sun, but since it is 2.1 times as massive, its expected lifetime is also one tenth of that of the Sun; both stars are at present approaching the midpoint of their life expectancies. Vega has an unusually low abundance of the elements with a higher atomic number than that of helium. Vega is also a variable star that varies slightly in brightness. It is rotating rapidly with a velocity of 236 km/s at the equator. This causes the equator to bulge outward due to centrifugal effects, and, as a result, there is a variation of temperature across the star's photosphere that reaches a maximum at the poles. From Earth, Vega is observed from the direction of one of these poles.Based on an observed excess emission of infrared radiation, Vega appears to have a circumstellar disk of dust. This dust is likely to be the result of collisions between objects in an orbiting debris disk, which is analogous to the Kuiper belt in the Solar System. Stars that display an infrared excess due to dust emission are termed Vega-like stars.

Stuttgart ( SHTUUT-gart, also US: STU(U)T-, STOOT-, SHTOOT-; German: [ˈʃtʊtɡaʁt] (listen); Swabian: Schduagert [ˈʒ̊d̥ua̯ɡ̊ɛʕd̥]; names in other languages) is the capital and largest city of the German state of Baden-Württemberg. Stuttgart is located on the Neckar river in a fertile valley known locally as the "Stuttgart Cauldron". It lies an hour from the Swabian Jura and the Black Forest. Its area has a population of 634,830, making it the sixth largest city in Germany. 2.8 million people live in the city's administrative region and 5.3 million people in its metropolitan area, making it the fourth largest metropolitan area in Germany. The city and metropolitan area are consistently ranked among the top 20 European metropolitan areas by GDP; Mercer listed Stuttgart as 21st on its 2015 list of cities by quality of living, innovation agency 2thinknow ranked the city 24th globally out of 442 cities and the Globalization and World Cities Research Network ranked the city as a Beta-status Global city in their 2014 survey. Stuttgart was one of the host cities for the official tournaments of the 1974 and 2006 FIFA World Cup. Since the 7th millennium BC, the Stuttgart area has been an important agricultural area and has been host to a number of cultures seeking to utilize the rich soil of the Neckar valley. The Roman Empire conquered the area in 83 AD and built a massive castrum near Bad Cannstatt, making it the most important regional centre for several centuries. Stuttgart's roots were truly laid in the 10th century with its founding by Liudolf, Duke of Swabia, as a stud farm for his warhorses. Initially overshadowed by nearby Bad Cannstatt, the town grew steadily and was granted a charter in 1320. The fortunes of Stuttgart turned with those of the House of Württemberg, and they made it the capital of their county, duchy, and kingdom from the 15th century to 1918.

Stuttgart prospered despite setbacks in the Thirty Years' War and devastating air raids by the Allies on the city and its automobile production during World War II. However, by 1952, the city had bounced back and it became the major economic, industrial, tourism and publishing centre it is today.Stuttgart is also a transport junction, and possesses the sixth-largest airport in Germany. Several major companies are headquartered in Stuttgart, including Porsche, Bosch, Mercedes-Benz, Daimler AG, and Dinkelacker.Stuttgart is unusual in the scheme of German cities. It is spread across a variety of hills (some of them covered in vineyards), valleys (especially around the Neckar river and the Stuttgart basin) and parks. This often surprises visitors who associate the city with its reputation as the "cradle of the automobile". The city's tourism slogan is "Stuttgart offers more". Under current plans to improve transport links to the international infrastructure (as part of the Stuttgart 21 project), the city unveiled a new logo and slogan in March 2008 describing itself as "Das neue Herz Europas" ("The new Heart of Europe"). For business, it describes itself as "Where business meets the future". In July 2010, Stuttgart unveiled a new city logo, designed to entice more business people to stay in the city and enjoy breaks in the area.Stuttgart is a city with a high number of immigrants. According to Dorling Kindersley's Eyewitness Travel Guide to Germany, "In the city of Stuttgart, every third inhabitant is a foreigner." 40% of Stuttgart's residents, and 64% of the population below the age of five, are of immigrant background.
