Informations

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.

Informations

Beersheba (; Hebrew: בְּאֵר שֶׁבַע‎ Be'er Sheva [be(ʔ)eʁ ˈʃeva(ʕ)], Arabic: بئر السبع‎, lit. Well of the Oath) is the largest city in the Negev desert of southern Israel. Often referred to as the "Capital of the Negev", it is the center of the fourth-most populous metropolitan area in Israel, the eighth-most populous Israeli city with a population of 209,687, and the second-largest city (after Jerusalem) with a total area of 117,500 dunams. The Biblical site of Beersheba is Tel Be'er Sheva, lying some 4 km distant from the modern city, which was established at the start of the 20th century by the Ottoman Turks. The city was captured by the British-led Australian Light Horse in the Battle of Beersheba (1917) during World War I. In 1947, Bir Seb'a (Arabic: بئر السبع‎), as it was known, was envisioned as part of the Arab state in the United Nations Partition Plan for Palestine. Following the declaration of Israel's independence, the Egyptian army amassed its forces in Beersheba as a strategic and logistical base.



In the Battle of Beersheba waged in October 1948, it was conquered by the Israel Defense Forces.Beersheba has grown considerably since Israel's independence. A large portion of the population is made up of the descendants of Sephardi Jews and Mizrahi Jews who immigrated from Arab countries after 1948, as well as smaller communities of Bene Israel and Cochin Jews from India. Second and third waves of immigration have taken place since 1990, bringing Russian-speaking Ashkenazi Jewish immigrants from the former Soviet Union, as well as Beta Israel immigrants from Ethiopia. The Soviet immigrants have made the game of chess a major sport in Beersheba, and it is now Israel's national chess center, with more chess grandmasters per capita than any other city in the world, making it the chess capital of the world in some regards.Beersheba is home to Ben-Gurion University of the Negev. This city also serves as a center for Israel's high-tech and developing technology industry.
