Czech Student Wins Junior Astronomy Olympiad

Viktorie Snášelová Dominates International Junior Astronomy Olympiad in Thailand

Viktorie Snášelová from Masaryk Grammar School in Plzeň won the gold medal and took first place overall at the 5th International Olympiad on Astronomy and Astrophysics for Juniors (IOAA-jr), Novinky reported. The competition ran from November 1 to 8 in Ubon Ratchathani, Thailand, bringing together 106 contestants from 25 countries.

Thai Princess Maha Chakri Sirindhorn officially opened the event for students under 16 years old, according to ČT24. Every member of the five-person Czech team earned an award, marking one of the strongest performances in the country’s history at international astronomy competitions.

Contestants solved astronomy problems without electronics

Contestants tackled difficult theoretical problems in astronomy and astrophysics without access to mobile phones or other electronics, according to Novinky. In one task, students used measured data to determine the distance of supernova 1987A by comparing the expansion velocity of ejected material with its apparent size on the sky.

Another task placed participants in the year 1866, requiring them to use three stars to find the position of a British merchant ship blown off course in the Gulf of Thailand and plot a route to the nearest port, Novinky reported. ČT24 noted that the practical portion included a planetarium session and a moon-based observation task, though bad weather cancelled planned night observations.

Snášelová won top scores among Czech competitors

Snášelová also captured the award for the highest score in the theoretical round and the prize for the top female competitor, Novinky reported. Dario Heinich from Šlapanice Grammar School and Lukáš Závodný from Břeclav Grammar School both received silver medals, Amélie Zemanová from Christiana Doppler Grammar School earned a bronze medal, and Vladimír Kopecký from Nad Alejí Grammar School received an honorable mention, according to Novinky and ČT24.

Snášelová followed the success of Alexe Faivre from Uherský Brod, who won the 2024 junior olympiad in Kathmandu, Nepal, giving the Czech Republic an absolute winner for the second time, Novinky reported. Snášelová also claimed a silver medal at the senior IOAA in Vietnam earlier this year, successfully medaling in both age divisions, according to ČT24.

Team leaders defended student point totals

Team leaders reviewed task assignments and joined moderation sessions with organizers to defend student point totals and advocate for additional credits, according to ČT24. Czech students have competed in the junior IOAA since its inception in Romania in 2022, while participation in the senior IOAA dates back to 2010.
