[14][19][33] Henry Draper took the first photograph of a star's spectrum in August 1872 when he took an image of Vega, and he also became the first person to show absorption lines in the spectrum of a star. [109] Consequently, the Chinese name for Vega is 織女一 (Zhī Nǚ yī, English: the First Star of Weaving Girl)[110] In Chinese mythology, there is a love story of Qixi (七夕) in which Niulang (牛郎, Altair) and his two children (β Aquilae and γ Aquilae) are separated from their mother Zhinü (織女, lit. 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. Celestia Vega is not only a YouTuber, she's currently working as a porn star. Vega is one of six A0V stars that were used to set the initial mean values for this photometric system when it was introduced in the 1950s. Because it is more massive, Vega burns up its hydrogen fuel more quickly than our Sun, so its lifetime as a main-sequence star is only about one billion years, or about a tenth as long as the Sun's life. The net proper motion of Vega is 327.78 mas/y,[78] which results in angular movement of a degree every 11,000 years. With a declination of +38.78°, Vega can only be viewed at latitudes north of 51° S. Therefore, it does not rise at all anywhere in Antarctica or in the southernmost part of South America, including Punta Arenas, Chile (53° S). Vega measures how much the price of an option will change when volatility … Radeon™ RX Vega Grafikkarten sind für Gamer die ihre Spiele in der höchsten Auflösung, der flüssigsten Framerate und mit maximalen Details genießen wollen. [14], In Chinese, 織女 (Zhī Nǚ), meaning Weaving Girl (asterism), refers to an asterism consisting of Vega, ε Lyrae and ζ1 Lyrae. While the Sun appears round, Vega is noticeably flattened. [44] Thus, Vega has a relatively flat electromagnetic spectrum in the visual region—wavelength range 350–850 nanometers, most of which can be seen with the human eye—so the flux densities are roughly equal; 2,000–4,000 Jy. Careful measurement of the star's position allows this angular movement, known as proper motion, to be calculated. [11] This group contains about 16 stars, including Alpha Librae, Alpha Cephei, Castor, Fomalhaut and Vega. [32], Astrophotography, the photography of celestial objects, began in 1840 when John William Draper took an image of the Moon using the daguerreotype process. Hence it is more likely to have been produced as the result of a relatively recent breakup of a moderate-sized (or larger) comet or asteroid, which then further fragmented as the result of collisions between the smaller components and other bodies. 0. It is also one of the Sun’s closer neighbours, at a distance of about 25 light-years. However, Vega may be much older than this group, so the membership remains uncertain. To standardize the magnitude scale, astronomers chose Vega to represent magnitude zero at all wavelengths. To maintain this amount of dust in orbit around Vega, a continual source of replenishment would be required. This is 60% larger than the radius of the star Sirius, while stellar models indicated it should only be about 12% larger. Precise measurements of this blueshift give a value of −13.9 ± 0.9 km/s. (2012)[98] and the Herschel Space Telescope. W.H. This change cast further doubt on Struve's data. Also known as Vegans, they were originated from Lyra so that they could colonise and dominate the dog star, Sirius. Retrieved from https://www.thoughtco.com/vega-star-facts-4137641. The faintest stars visible to the unaided eye are sixth magnitude, while the brightest in the night sky, Sirius, is of magnitude −1.46. It is definitely of the nature of Venus. Der Stern ist Teil des großen Sommerdreiecks und im weißen Licht der hellste Stern des Nordhimmels. At 5480 Å, the flux density is 3,650 Jy with an error margin of 2%. Auden's 1933 poem "A Summer Night (to Geoffrey Hoyland)"[119] famously opens with the couplet, "Out on the lawn I lie in bed,/Vega conspicuous overhead". It is now so entered in the IAU Catalog of Star Names. Vega (Alpha Lyrae) is a beautiful bluish-white star located 25 light-years away in the constellation of Lyra. [122], Coordinates: 18h 36m 56.3364s, +38° 47′ 01.291″, This article is about the star. Vega has an unusually low abundance of the elements with a higher atomic number than that of helium. The VEGA Conflict Wiki has been migrated to Gamepedia, effective from January 27th, 2018. Vega has been one of the most important stars to humanity since ancient times because it is very bright and easily recognized by its blue color. Vega, brightest star in the northern constellation Lyra and fifth brightest in the night sky, with a visual magnitude of 0.03. The star is about 40 times brighter than the Sun, but because it's 25 light-years away, it seems dimmer. Meaning: Of the Lyre. It forms one corner of the Summer Triangle.. Vega Meaning. [Medieval Latin, from Arabic (an-nasr) al-wāqi', the falling (eagle), Vega : al-, the + wāqi', falling, active participle of waqa'a, to fall; see wqʕ in Semitic roots.] The astral V… Vega is the brightest star in the northern constellation of Lyra. Because of the star's orientation with respect to Earth, the bulge appears unusually pronounced. 0. Vega is seen in the summer sky in the Northern Hemisphere, where it is part of the constellation Lyra. Meanings and history of the name Vega. Helmenstine, Anne Marie, Ph.D. "Vega Star Facts on Our Future North Star." [note 5], In 2021, a paper analyzing 10 years of spectra of Vega detected a candidate 2.43-day signal around Vega, statistically estimated to have only a 1% chance of being a false positive. Thus most astronomers at the time, including Struve, credited Bessel with the first published parallax result. It is a gaseous body having a highly compressed core, in which energy is generated by thermonuclear reactions (at about 15 million kelvins), surrounded by less dense radiative and convective zones serving to transport the energy to the surface (the photosphere).
