The conference will take place from 17-21 September, 2018 at Byurakan Astrophysical Observatory, Byurakan, Armenia. The meeting is devoted to V. Ambartsumian’s 110 year anniversary, the great Armenian scientist, whose fundamental discoveries changed our views on the evolution of cosmic objects. Ambartsumian founded the Byurakan Observatory in 1946. He was the second and longest-serving president of the Armenian Academy of Sciences (1947–1993) and also served as the president of the International Astronomical Union from 1961 to 1964 and was twice elected the President of the International Council of Scientific Unions (1968–1972).

A number of important astronomical meetings have been organized in Armenia, mostly in the Byurakan Astrophysical Observatory (BAO): IAU Symposia: #29 in 1966 (Non-Stable Phenomena in Galaxies), #121 in 1986 (Observational Evidence of Activity in Galaxies), #137 in 1989 (Flare Stars in Star Clusters, Associations and Solar Vicinity), #194 in 1998 (Activity in Galaxies and Related Phenomena) and #304 in 2013 (Multiwavelength AGN Surveys and Studies), IAU Colloquium #184 in 2001 (AGN Surveys), as well as the all-European JENAM meeting in 2007. Moreover, the Byurakan International Summer Schools (BISS) are being organized since 2006, and five successful schools have been held in 2006, 2008, 2010 (combined with the 32th IAU ISYA), 2012 and 2016.
