Astronomy Day in Armenia (18/09)

Since 2009, by the decision of the Government of Armenia, on September 18, the country celebrates the Day of Astronomy, which is traditionally timed to hold various thematic events.

The date was chosen due to the fact that on September 18, 1908, Academician Viktor Amazaspovich Hambartsumyan, an outstanding Armenian scientist, the founder of theoretical astrophysics, the National Hero of Armenia, was born in Tiflis. As Minister of Education and Science of Armenia Spartak Seyranyan said, Hambardzumyan's great legacy is a contribution to world astronomy.

Twice Hero of Socialist Labor, twice winner of the Stalin Prize and the State Prize of the Russian Federation, Viktor Ambartsumian worked in the field of physics of stars and nebulae, stellar astronomy and dynamics of stellar systems, cosmogony of stars and galaxies. Among his many scientific achievements are the theory of light scattering in turbid media, stellar associations and the evolution of stars, the physics of stellar shells and extragalactic astronomy.

A minor planet, as well as the Byurakan Observatory in Armenia, founded by the great scientist, are named after Academician Ambartsumyan.

Today Byurakan Astrophysical Observatory named after V.A. Hambardzumyan is one of the leading scientific institutions of the National Academy of Sciences of Armenia. The observatory is located in the Aragatsotn region on the southern slope of Mount Aragats at an altitude of 1490 m. The complex of buildings of the observatory is an architectural monument. Over the years of its existence, the employees of the observatory have carried out a lot of work, research and discoveries in the field of astronomy. Also, 4 symposiums of the International Astronomical Union were held here.
