It is located on the slope of Mount Aragats in the village of Byurakan in Armenia. HistoryFounded in 1946 by Viktor Hambardzumyan, it was one of the main astronomy centers of the USSR. The buildings were designed by architect Samvel Safarian. The hotel, central building and structures are for astronomical instruments.[1] The observatory has discovered special star clusters - stellar associations (1947),[1] more than 1,000 flare stars, dozens of supernovae, hundreds of Herbig–Haro objects and cometary nebulae, hundreds of galaxies. After the breakup of the Soviet Union, the observatory fell into hard times. The first conference was held in November 1951 on the topic of stellar associations. On 19 September 1956 a major meeting on non-stable stars was held.[1] It has been the site of two major conferences on SETI, and is recognised as the regional center for astronomical research.[1] Directors included V. A. Ambartsumian till 1988, E. Ye. Khachikian till 1993, H. A. Harutyunian from 1993 to 1994, and A. R. Petrosian from 1994-1999. Khachikian returned as director from 1999–2003 and Harutyunian also returned after this.[1] EquipmentByurakan Observatory's main telescope is a 2.6 m cassegrain reflector, along with a 1 and .5 m Schmidt camera as well as other smaller telescopes. ResultsThe First Byurakan Survey commenced in 1965 using the Schmidt telescope. It revealed 1500 galaxies with ultraviolet excess known as the Markarian galaxies.[1] These galaxies are designated "Markarian" or "Mrk" followed by a number, for example Mrk 501. The Second Byurakan Survey, 1974 to 1991[2], looked for emission line and ultraviolet excess galaxies, and quasars as well[1].
