Meeting of the Polish Astronomical Society which attracted over 170 astronomers took place in mid-September in Zielona Góra. Representatives of the Copernicus Science Centre presented our Heavens of Copernicus Planetarium. During the meeting, the Polish Astronomical Society awarded the Quality Certificate to our Planetarium. This unique distinction emphasises the Planetarium’s high educational and substantive level, as well as its contribution to education and popularising astronomy in Poland. By granting its certificate, the Polish Astronomical Society recommends to wider audience only the best planetaria operating in Poland.
