Materials funded by European Southern Observatory (ESO) - postcards, books and posters presenting beautiful astronomical objects - have arrived at the Silesian Planetarium. They will serve as additional prizes for the participants of 5th International Olympiad on Astronomy and Astrophysics.
At the last count, it appears that we will have 30 teams from 27 countries (3 guest teams, from China, Iran and Poland). Unfortunately at the last minute the teams from Egypt and Turkey have been unable to attend. Even so, this will be the largest IOAA so far, and with several new countries - particularly from Europe. We welcome you all in 3 weeks!
