Tampere vs Vega

Informations

Tampere (, US also , Finnish: [ˈtɑmpere] (listen); Swedish: Tammerfors [tɑmːærˈforsː] (listen); Latin: Tammerforsia) is a city in Pirkanmaa in the western part of Finland. Tampere is the most populous inland city in the Nordic countries; it has a population of 238,140 with the urban area holding 334,112 people and the metropolitan area, also known as the Tampere sub-region, holding 385,301 inhabitants in an area of 4,970 km2 (1,920 sq mi). Tampere is the second-largest urban area and third most-populous individual municipality in Finland, after the cities of Helsinki and Espoo and the most populous Finnish city outside the Greater Helsinki area, within which both Helsinki and Espoo are located. Tampere is a major urban, economic, and cultural hub for central Finland.Tampere is wedged between two lakes, Näsijärvi and Pyhäjärvi. Since the two lakes differ in level by 18 metres (59 ft), the rapids linking them, Tammerkoski, have been an important power source throughout history, most recently for generating electricity. Tampere is dubbed the "Manchester of the North" for its industrial past as the former center of Finnish industry, and this has given rise to its Finnish nickname "Manse" and terms such as "Manserock".

Also, Tampere has been officially declared the "Sauna Capital of the World", because it has the most public saunas in the world.Helsinki is approximately 160 kilometres (100 mi) south of Tampere, and can be reached in 1 hr, 31 minutes by Pendolino high-speed rail service and 2 hours by car. The distance to Turku is roughly the same. Tampere–Pirkkala Airport is Finland's eighth-busiest airport, with over 230,000 passengers in 2017. Tampere also serves as an important transit route for three Finnish highways: Highway 3 (E12), Highway 9 (E63) and Highway 12. Tampere ranked 26th in the list of 446 cities in the world's hipster cities, and it has often been rated as the most popular city in Finland.By 2021, a new multi-purpose sports and entertainment center, Tampere Deck Arena, is nearing completion.

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.
