For the first time the international conference "Planetarium of the XXI century" was held on April 6-7, 2012 at the Valentina Tereshkova Cultural and Educational Center.
Our center is the first newly built planetarium in Russia. It includes: a modern classical planetarium, an observatory, a museum of space exploration and other interesting objects. The conference was timed to the first year of the cultural and educational center. It is significant that this conference was held in the year of the anniversary of the first woman-cosmonaut Valentina Tereshkova.
The second time the conference was held in the framework of the International Festival "Reflection of the Universe" in the period from 16 to 19 June 2015. After that, the Organizing Committee of the conference decided to hold the conference once every two years.
