The very first edition of the International Astronomy Olympiad took palce in June 1996 in Moscow, Russia. Bulgaria has been part of it every year since 1998 and each year our competitors come back home with at least two medals. The participants in the Bulgarian national team are being chosen from the winners in the all four rounds of the National Astronomy Olympiad. Leaders of the team are docent Eva Bozhurova and Nikola Karavassilev.
By 2015 our students have won 71 medals at all: 13 golden, 23 silver and 35 bronze. 18 medals have been won for the very last 3 years! By this time, many of these talanted children are now professors in some of the world's best Astronomy centres.
LNSOTA supports the participation of the team in the International Astronomy and Astrophysics Olympiad as well.
