Amsterdam vs Vega

Informations

Amsterdam (, UK also; Dutch: [ɑmstɛrˈdɑm] (listen)) is the capital and most populous city of the Netherlands with a population of 872,680 within the city proper, 1,558,755 from the metropolitan region and 2,480,394 from the metropolitan area. Located within the province of North Holland, Amsterdam is colloquially referred to as the"Venice of the North", attributed by the large number of canals that form a UNESCO World Heritage Site. Amsterdam's name derives from Amstelredamme, indicative of the town's origin around a dam in the river Amstel. Originating as a small fishing village in the late 12th century, Amsterdam became one of the most important ports in the world during the Dutch Golden Age of the 17th century, and became the leading centre for trade and finance. In the 19th and 20th centuries, the city expanded and many new neighbourhoods and suburbs were planned and built. The 17th-century canals of Amsterdam and the 19--20th century Defence Line of Amsterdam are on the UNESCO World Heritage List. Sloten, annexed in 1921 from the municipality of Amsterdam, is the oldest part of town, dating to the 9th century. Amsterdam's main attractions include its historic canals, the Rijksmuseum, the Van Gogh Museum, the Stedelijk Museum, Hermitage Amsterdam, the Concertgebouw, the Anne Frank House, the Scheepvaartmuseum, the Amsterdam Museum, the Heineken Experience, the Royal Palace of Amsterdam, Natura Artis Magistra, Hortus Botanicus Amsterdam, NEMO, the red-light district and Several cannabis coffee shops. It drew over 5 million international visitors in 2014. The city is also well known for its nightlife and festival activity; with several of its clubs (Melkweg, Paradiso) among the world's most famous. Primarily known for its artistic heritage, elaborate canal system and narrow houses with gabled façades; well-preserved legacies of the town's 17th-century Golden Age.

These attributes are arguably responsible for bringing millions of Amsterdam's visitors yearly. Cycling is vital to the city's character, and there are a lot of bike paths. The Amsterdam Stock Exchange is considered the earliest"modern" securities market stock exchange in the world. As the industrial capital of the Netherlands and among the top financial centres in Europe, Amsterdam is considered an alpha world city by the Globalization and World Cities (GaWC) research group. The city is also the cultural capital of the Netherlands. Many large Dutch institutions have their headquarters in the city, such as: the Philips conglomerate, AkzoNobel, Booking.com, TomTom, and ING. Moreover, many of the world's biggest companies are located in Amsterdam or have established their European headquarters in the city, such as leading technology companies Uber, Netflix and Tesla. In 2012, Amsterdam was ranked the second best city to live in by the Economist Intelligence Unit (EIU) and 12th globally on quality of living for infrastructure and environment by Mercer. The city was ranked 4th place globally as top tech hub in the Savills Tech Cities 2019 report (2nd in Europe), and 3rd in innovation by Australian innovation agency 2thinknow in their Innovation Cities Index 2009. The Port of Amsterdam is the fifth largest in Europe. The KLM hub and Amsterdam's key airport: Schiphol, is the Netherlands' busiest airport in addition to the third largest in Europe and 11th busiest airport in the world. The Dutch capital is considered one of the most multicultural cities in the world, with at least 177 nationalities represented.A few of Amsterdam's notable residents throughout history include: painters Rembrandt and Van Gogh, the diarist Anne Frank, and philosopher Baruch Spinoza.

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.
