Byurakan was founded in 1946 by Viktor Ambartsumian on the southern slope of Aragats at about 1,500 metres, and it did serious work: the Markarian survey of galaxies with active nuclei came from here, and the site was one of the Soviet Union's main astrophysical centres. It is still a working institute. Visits are arranged in advance and typically include the 2.6-metre telescope dome, the Schmidt telescope used for the survey, and, on clear nights, observing.
What you actually see
- The 2.6-metre telescope - the observatory's main instrument, in its dome.
- The Schmidt telescope - the wide-field instrument the Markarian survey was made with.
- The site - 1946 buildings on the mountain slope, designed as a working campus.
- Night observing - sessions arranged for groups when the sky is clear.
When to go
May to October for the road and the weather. Night sessions depend entirely on cloud and are cancelled often. Booking well ahead is necessary; this is not a walk-in attraction.
Honest expectations
It is a research institute, not a visitor centre, and the tour depends on staff availability. Equipment is old and some of it is no longer in use. Winter access to the site can be difficult.
Nearby
Amberd fortress is higher on the same road, and the Alphabet Monument is nearby.
