Valencia vs Vega

Informations

Valencia (Spanish: [baˈlenθja]), officially València (Valencian: [baˈlensia] (locally) or [vaˈlensia]), is the capital of the autonomous community of Valencia and the third-largest city in Spain after Madrid and Barcelona, surpassing 800,000 inhabitants in the municipality. The wider urban area also comprising the neighbouring municipalities has a population of around 1.6 million. Valencia is Spain's third-largest metropolitan area, with a population ranging from 1.7 to 2.5 million depending on how the metropolitan area is defined. The Port of Valencia is the 5th-busiest container port in Europe and the busiest container port on the Mediterranean Sea. The city is ranked as a Gamma-level global city by the Globalization and World Cities Research Network.Valencia was founded as a Roman colony by the consul Decimus Junius Brutus Callaicus in 138 BC and called Valentia Edetanorum. In 714, Moroccan and Arab Moors occupied the city, introducing their language, religion and customs; they implemented improved irrigation systems and the cultivation of new crops as well. Valencia was the capital of the Taifa of Valencia. In 1238 the Christian king James I of Aragon conquered the city and divided the land among the nobles who helped him conquer it, as witnessed in the Llibre del Repartiment.

He also created the new Kingdom of Valencia, which had its own laws (Furs), with Valencia as its main city and capital. In the 18th century Philip V of Spain abolished the privileges as punishment to the kingdom of Valencia for aligning with the Habsburg side in the War of the Spanish Succession. Valencia was the capital of Spain when Joseph Bonaparte moved the Court there in the summer of 1812. It also served as the capital between 1936 and 1937, during the Second Spanish Republic. The city is situated on the banks of the Turia, on the east coast of the Iberian Peninsula, fronting the Gulf of Valencia on the Mediterranean Sea. Its historic centre is one of the largest in Spain, with approximately 169 ha (420 acres). Due to its long history, Valencia has numerous celebrations and traditions, such as the Fallas, which were declared Fiestas of National Tourist Interest of Spain in 1965 and an Intangible cultural heritage by UNESCO in November 2016. Joan Ribó from Compromís has been the mayor of the city since 2015.

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.
