The stars fell, and the heavens and the earth crumbled.

The world is destroyed because of me, and because I am born again.

Vega, also known as Vega or α α Lyrae, is the brightest star in the constellation Lyrae, located about 25 light-years from Earth.

Due to its extremely high rotation speed, it appears distinctly oblate spherical, with an equatorial radius 19% greater than the polar radius.

In the ancient Chinese myth of "Cowherd and Weaver Girl", the Weaver Girl is the granddaughter of the Emperor of Heaven, so she is also known as the Heavenly Sun.

In the summer in the Northern Hemisphere, observers are likely to see Vega with the naked eye near the zenith.

It was the polar star of the Northern Hemisphere around 12000 BC, and due to precession, it will become the North Star again in 13727, when its declination will reach +86°14'.

It was the first star outside the Sun to be photographed by humans, the first star to have spectral records, one of the first stars to estimate distance by parallax measurement, a calibrated baseline for measuring luminosity scales, and one of the stars used by the UBV photometric system to define averages. In the 19th century, the astronomer Pusen devised the concept of apparent magnitude and defined it as the magnitude 0 of each band, which is known as the "Vega magnitude". Later, it was believed that Vega's luminosity was changing, so other standards were used, and its apparent magnitude was no longer 0.

It is the fifth brightest star in the night sky and the second brightest star in the Northern Hemisphere, after Arcturus. Along with Arcturus and Sirius, it is one of the brightest stars near the Sun.

Basic meaning

Astrophotography for astrophotography was born in 1840 when John J. William · Draber used daguerreotype photography to photograph the moon. Harvard University Observatory scientist George Phillips · George Phillips Bond and John Bond Adams · John Adams Whipple's photograph of Vega on July 17, 1840, became the first star to be photographed (other than the Sun), also using daguerreotype. Henry · While photographing Vega in August 1872, Draber obtained the first photograph of the spectrum of stars. This made him the first person to show the absorption spectral lines of stars. Astronomers have identified similar spectral lines in the sun's spectrum. William · In 1879, Huggins used spectral photographs of Vega and similar stars to identify a series of 12 "very strong spectral lines" that are prevalent in this group of stars. Astronomers later identified this as the Balmer lineage of the hydrogen atom. Beginning in 1943, astronomers used Vega's spectrum as one of the criteria for classifying other stars.

Astronomers can measure the distance between Vega and Earth by the parallax of Vega relative to the background star as the Earth orbits the Sun. The first person in history to publish stellar parallax was Vasily M. Yakovlevich · Struve, who claimed that Vega had a parallax value of 0.125", but Friedrich William · Bessel was skeptical of the data published by Struvey. When Béssel announced that the star system Cygnus 61 had a parallax of 0.314", Struve corrected Vega's parallax to about twice as much. This correction made Struvey's published data even more questionable, so that most astronomers at the time (including Struvey) agreed that Bessel's data was the first parallax observation in history. Surprisingly, however, the data originally published by Struve is actually very close to the current astronomer acceptance value of 0.129".

The brightness of stars seen on Earth is expressed using a standardized logarithmic scale – apparent magnitude, which decreases as the brightness of the star increases. The faintest star visible to the naked eye is the 6th magnitude star, Vega, also known as Vega or α α Lyrae, the brightest star in the constellation Lyrae, located about 25 light-years from Earth.

The brightness of stars seen on Earth is expressed using a standardized logarithmic scale – apparent magnitude, which decreases as the brightness of the star increases. The faintest star visible to the naked eye is a magnitude 6, while the brightest star, Sirius A, has an apparent magnitude of -1.47. To standardize this logarithmic scale, astronomers chose Vega as the magnitude 0 for all wavelengths. For this reason, for many years, Vega was used as a luminance scale for absolute photometry. However, this rule has not been carried forward to this day, and the zero point of apparent magnitude is now generally expressed in terms of the amount of light flowing at a specific value. This method is much easier for astronomers because Vega is not always a standard scale for measurement, and astronomers choose Vega as the magnitude 0 for all wavelengths.

However, this rule has not been carried forward to this day, and the zero point of apparent magnitude is now generally expressed in terms of the amount of light flowing at a specific value. This method is easier for astronomers, as Vega cannot be used as a measure forever. To standardize this logarithmic scale, astronomers chose Vega as the magnitude 0 for all wavelengths.
