Day 3

The main event of the third day of the Open World Astronomy Olympiad was the theoretical round. It consisted of eight problems each of them including several different questions: from simple warm-ups to complex research tasks. For example, one problem required participants to analyze an eclipsing binary star system, while another involved analyzing a gravimeter satellite model.

"The theoretical round also included geometry problems. They are not so simple: it is necessary to build a specific model to find the best solution. We believe that the set of problems turned out well designed. Their level of difficulty will become clear after grading. The jury members are thoughtfully reviewing the participants' work, carefully considering their ideas and problem-solving approaches," notes Ivan Uteshev, the member of the Academic Committee of the Open World Astronomy Olympiad and a senior methodologist at the Center of Pedagogical Mastery.

For Ekaterina Churkina, a participant from Russia, the problems in the theoretical round were fascinating. She is confident that astronomy provides answers to many questions about the structure of the universe.

"I particularly enjoyed the problem about a star cluster. We were asked to identify the type of the cluster, to determine how far it is from us and at what height it can be seen in Sochi. I am sure that the Olympiad tasks will help me fill the gaps in my knowledge, and the international connections will be a foundation for collaborative breakthrough projects in science. I would like to dedicate my future to studying what lies beyond Earth, exploring distant spaces, and conquering new frontiers for humanity," Ekaterina shares.
