Ashgabat vs Vega

Informations

Ashgabat (Turkmen: Aşgabat; Ашгабат, pronounced [ɑʃʁɑˈbɑt], Persian: عشق آباد‎; Russian: Ашхабад), formerly named Poltoratsk (Russian: Полтора́цк, IPA: [pəltɐˈratsk]) between 1919 and 1927, is the capital and the largest city of Turkmenistan. It is situated between the Karakum Desert and the Kopet Dag mountain range in Central Asia. It is also near the Iran-Turkmenistan border. The city was founded in 1881 on the basis of an Ahal Teke tribal village, and made the capital of the Turkmen Soviet Socialist Republic in 1924.

Much of the city was destroyed by the 1948 Ashgabat earthquake but has since been extensively rebuilt under the rule of Saparmurat Niyazov’s "White City" urban renewal project, resulting in monumental projects sheathed in costly white marble. The Soviet-era Karakum Canal runs through the city, carrying waters from the Amu Darya from east to west. Since 2019, the city has been recognized as having one of the highest costs of living in the world largely due to Turkmenistan's inflation and import issues.

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.
