Rosario (Spanish pronunciation: [roˈsaɾjo]) is the largest city in the central Argentina province of Santa Fe. The city is located 300 km (186 mi) northwest of Buenos Aires, on the west bank of the Paraná River. Rosario is the third-most populous city in the country, and is also the most populous city in Argentina that is not a capital (provincial or national). With a growing and important metropolitan area, Greater Rosario has an estimated population of 1,700,000 [1]as of 2020. One of its main attractions includes the neoclassical, Art Nouveau, and Art Deco architecture that has been retained over the centuries in hundreds of residences, houses and public buildings.
Rosario is the head city of the Rosario Department and is located at the heart of the major industrial corridor in Argentina. The city is a major railroad terminal and the shipping center for north-eastern Argentina. Ships reach the city via the Paraná River, which allows the existence of a 10-metre-deep (34 ft) port.

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.
