If you took a long exposure photograph of the northern sky today, the stars would appear as trails around Polaris. If it were spinning about 10% faster, it would break apart! Conventional color descriptions are traditional in astronomy, and represent colors relative to the mean color of an A class star, which is considered to be white. There are many variations. Thanks to its high brightness, Vega is clearly visible when observed from locations with dark skyes, and should be also quite easily visible from light polluted areas. [A scanned copy can be viewed on this webpage] Alpha (α) Lyra, Vega, is a pale sapphire star in the Lyre. In Japan, Vega is called Orihime, a celestial princess or goddess.

In general, a star's temperature determines its color, from red to blue-white. Vega’s spectral type is A (white) and its luminosity class V (main sequence). The constellation Lyra the Harp and its brightest star Vega. Right now, the North Star is Polaris, but Vega was the northern pole star around 12,000 BC and will the pole star again about the 13,727. Its said that when Orpheus played this harp, neither god nor mortal could turn away. Vega is the brightest star in school, working harder than any other student at Starling Academy. Between the Gamma and Beta stars is the famous Ring Nebula, visible in small telescopes. In another 500 million years or so, Vega will become a class-M red giant, after which it will lose most of its mass and become a white dwarf. Let me get back to Vega though. Applying polish can be tricky, try to apply just enough to cover the nail without showing brush strokes. Vega is seen in the summer sky in the Northern Hemisphere, where it is part of the constellation Lyra. Vega is at the top of the triangle, with Deneb below it and to the left and Altair below both stars and to the right. Observers in the Northern Hemisphere typically begin noticing Vega in the evening around May, when this star comes into view in the northeast in mid-evening. Greenstar’s Vega Series of Floodlight Luminaires is a high performance, energy-efficient, solid-state fixture ideal for a wide variety of applications. For Vega 5.0 and higher, if a color array is provided, the colors will be interpolated to form a new scheme; use the scale interpolate property to set the interpolation type (defaults to linear RGB interpolation). Many allow you to wave the phone across the sky until you see the name. It will Many Japanese celebrations of Tanabata are held in July, but sometimes they are held in August. Vega (Star) Color-magnitude diagram. The "blue" photons emission is about twice that of the "red" number of photons. While the Sun has a central radiation zone at its core covered by a convection zone, Vega has a convection zone at its core that distributes ash from its nuclear reaction. When Vega is the pole star, a long exposure photograph would show stars circling it. You can see the Summer Triangle in the evening beginning around June, through the end of each year. It’s sometimes called the Harp Star. Libby thought life was that easy for everyone until a few years ago when she met a girl … The photo above shows a small section of a starfield in Sagittarius taken by the HST from space. Spectral types are named with a … The colour of a star is primarily a function of its effective temperature. Vega is a classic class A (A0) white main sequence dwarf star, like the Sunquietly running off the nuclear fusion of hydrogen deep in its core, with a sort of average effective surface temperature of about 9500 degrees Kelvin. Vega in history and myth. Used with permission. The B–V color indexes of stars range from −0.4 for the bluest stars, with temperatures of about 40,000 K, to +2.0 for the reddest stars, with temperatures of about 2000 K. Vega is also known as Alpha Lyrae (α Lyrae, Alpha Lyr, α Lyr), as it is the principle star in the constellation Lyra, the lyre. If it rains, the raindrops are thought to be Orihime’s tears because Hikoboshi could not meet her. It’s said that when Orpheus played this harp, neither god nor mortal could turn away. 4. age main sequence star like Vega star estimated to be about 1 billion years old, compared with the Sun which is expected to reach the age of 10 billion years. In northern Canada, Alaska, and most of Europe, Vega never sets. Orihime and her lover Hikoboshi meet on a bridge of magpies across the Celestial River, each year on the 7th night of the 7th moon. Vega appears to be surrounded by a disk of dust. Vega is a hot star: class A0 with a surface temperature of about 9700K. Vega's spectral class is A0V, making it a blue-tinged white main sequence star that is fusing hydrogen to helium in its core. The blue-white star Vega via Fred Espenak. Another factor also contributes to Vega’s brightness — the st… Vega is blue-white in color. At this time, no planet has been definitively identified orbiting Vega, but its possible terrestrial planets could orbit near the star, probably in its equatorial plane. 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. "Absolute magnitude" is defined as the magnitude a star would have if we picked it up and placed it exactly 10 parsecs away from the Sun; that's very roughly as close as the star Vega, and a bit more distant than the Sun's closest neighbors. Wega, less correctly Vega, originated in the Alfonsine Tables from the Waki of the Arabs, Bayer having both titles; Scaliger, Waghi; Riccioli, Vuega vel Vagieh; and Assemani, Veka.

From a latitude including New York and Madrid, Vega is only below the horizon about seven hours a day, so it can be viewed any night of the year. Vega is one of the brightest stars in the night sky. You can see Vega in very early evening by June – and high in the east by August evenings – high overhead on autumn evenings – in the northwestern quadrant of the sky on December evenings. Come to know it, and you will see. Vega was one of the stars used to define the magnitude scale, so it has an apparent magnitude around 0 (+0.026). The two lovers are placed in the sky, separated by the Celestial River or Milky Way. Vega — like similar stars Fomalhaut, Sirius, and Alpha Centauri — is a main-sequence star whose brilliance can be attributed partially to its close proximity to us, astronomically speaking, at just 25 light-years away. Vega is the fifth brightest star visible from Earth, and the third brightest easily visible from mid-northern latitudes, after Sirius and Arcturus. But the most beautiful story relating to Vega comes from Asia. Sometimes Hikoboshi’s annual trip across the Celestial River is treacherous, though, and he doesn’t make it. Separated in the night sky by the Milky Way, or Celestial River, the two lovers are allowed to meet only once a year. In western culture, Vega is often called the Harp Star. The G is the general spectral type, G is a main-sequence star, or of yellow color and the 2 means that it is 2/10 of the way to a spectral type K and V is its luminosity and classifies the Sun as either a dwarf or more properly a main-sequence star. The little constellation Lyra has some interesting features. The Earth's axis of rotation precesses, like a wobbling toy top, which means "north" changes over a period of around 26,000 years.
