Byurakan Astrophysical Observatory marks 80th anniversary

In 2026, the Byurakan Astrophysical Observatory marks the 80th anniversary of its founding. Established in 1946 at the initiative of renowned Armenian scientist and academician Viktor Ambartsumian, the observatory has become one of Armenia’s scientific symbols and a major astronomical research center in the region.

The observatory is located on the southern slopes of Mount Aragats near the village of Byurakan, where the high altitude and clear skies provide favorable conditions for astronomical observation.

From its earliest years, the institution has played a key role in astrophysical research. In 1947, Ambartsumian discovered stellar associations – groups of young stars – demonstrating that stars are born in clusters and that star formation continues in the present universe. The discovery significantly reshaped scientific understanding of how stars form.

The observatory also hosted several projects of global significance. Among the most notable was the First Byurakan Survey, also known as the Markarian Survey, led by astronomer Benjamin Markarian. The survey identified thousands of galaxies with ultraviolet excess, now widely known as Markarian galaxies. The observational archive from this program has been inscribed in UNESCO’s Memory of the World Register.

Today, the Byurakan Astrophysical Observatory continues its scientific, educational and public mission as one of Armenia’s leading research institutions. It conducts astrophysical studies, hosts international conferences, and organizes summer schools and educational programs for young scientists.

Over the past eight decades, Byurakan has become not only a major center for astronomical research but also a symbol of Armenian scientific thought, continuing to inspire new generations of researchers exploring the mysteries of the universe.
