Overview
An educational science competition open to students from around the world: Unleash your astronomy skills and expand your knowledge through diverse problems that explore the universe. Win awards and telescopes signed by Nobel Prize laureates!
Details
The International Astronomy and Astrophysics Competition (IAAC) is a global educational competition based in Germany that promotes student engagement in space science and scientific learning worldwide. The competition consists of three online rounds and targets students both in school and at university.
The submission deadline for this year's Qualification Round is Friday, 04 July 2025. Participants can win awards, prizes, and telescopes signed by astronaut Frank De Winne and Nobel Prize laureates François Englert, Gerard't Hooft, Michel Mayor, and Didier Queloz.
Process and Rounds
Qualification Round
The Qualification Round is the first stage and consists of five astronomy problems. The problems in the Qualification Round encompass a wide range of topics, varying in difficulty and discipline. Some of the problems test your astronomy knowledge, others require calculations. Each problem gives 5 points, and to qualify for the Pre-Final Round in August 2025, you have to score at least 15, 17, or 20 points based on your age group .
Pre-Final Round
Qualified participants can register for the Pre-Final Round. The problems will be more challenging but also more engaging! You have four days to solve the problems, which include reading a real-world research paper. The Pre-Final Round consists of six problems that vary in difficulty, points, and subject: 2x Basic Problems (4 Points), 2x Advanced Problems (6 Points), and 2x Research Problems (8 Points).
All participants who are qualified and registered for the Pre-Final Round will receive the problems via email or via their participant account on Thursday, 14 August 2025. From that day on, you have until Sunday, 17 August 2025 to solve as many problems as possible. This year's registration costs are 11 EUR to fund the competition.
Final Round
Participants who have solved the Pre-Final Round successfully are qualified to participate in the Final Round: a multiple-choice online exam with 20 questions. The questions require knowledge of astronomy and astrophysics, as well as the content of the previous rounds.
The online exam is conducted in the participant's school, where a teacher supervises each finalist. Alternatively, participants can also self-record their and upload the video. In this case, no teacher is needed. The awards and prizes are given to the finalists with the most points in the Final Round.
