Vega vs Łódź

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.

Łódź (Polish: [wutɕ] (listen)), written in English as Lodz, is the third-largest city in Poland and a former industrial centre. Located in the central part of the country, it has a population of 679,941 (2019). It is the capital of Łódź Voivodeship, and is located approximately 120 kilometres (75 mi) south-west of Warsaw. The city's coat of arms is an example of canting, as it depicts a boat (łódź in Polish), which alludes to the city's name. Łódź was once a small settlement that first appeared in 14th-century records. Despite being granted town rights in 1423, it remained the private property of the Kuyavian bishops and clergy until the late 18th century. The Second Industrial Revolution brought rapid growth in textile manufacturing and in population due to the inflow of migrants, notably Germans and Jews. Ever since the industrialization of the area, the city has struggled with multinationalism and social inequalities, which were documented in the novel The Promised Land by Nobel Prize-winning author Władysław Reymont. The contrasts greatly reflected on the architecture of the city, where luxurious mansions coexisted with redbrick factories and dilapidated tenement houses.

The industrial development and demographic surge made Łódź one of the largest cities in Poland. Under the German occupation during World War II, Łódź was briefly renamed to Litzmannstadt in honour of Karl Litzmann. The city's large Jewish population was forced into a walled zone known as the Łódź Ghetto, from which they were sent to German concentration and extermination camps. The city itself sustained insignificant damage during the war and became Poland's temporary seat of power in 1945. Łódź experienced a sharp demographic and economic decline after 1989. It was only in the 2010s that the city began to experience revitalization of its neglected downtown area. Łódź is ranked by the Globalization and World Cities Research Network on the “Sufficiency” level of global influence and is internationally known for its National Film School, a cradle for the most renowned Polish actors and directors, including Andrzej Wajda and Roman Polanski. In 2017, the city was inducted into the UNESCO Creative Cities Network and named UNESCO City of Film.
