Applications are open for the International Astronomy and Astrophysics Competition 2026. The International Astronomy and Astrophysics Competition is an educational science competition that enables students from all countries to test their skills in astronomy and astrophysics. Participants can receive certificates, awards, cash prizes, and global recognition.
Since 2019, thousands of students from around the world have participated, forming a global network. Participating allows you to apply your astronomy skills to interesting problems and to learn about topics beyond the school curriculum.
Prizes
- The top performers receive the 1st, 2nd, and 3rd prizes, with awards worth $1,500 USD, including cash prizes and telescopes signed by astronaut Frank De Winne and Nobel Prize laureates François Englert, Gerard ‘t Hooft, Michel Mayor, and Didier Queloz.
- All participants receive participation certificates.
- There are also national awards for the best participants from each country.
Eligibility
Current high school and university students from all grades and countries are eligible. There are three age groups:
- Junior: 10th Grade and below (and < 16 years of age)
- Youth: 11th to 13th Grade (and < 19 years of age)
- Senior: 1st Year College/University and higher (or ≥ 19 years of age)
Application
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 May 2026, you have to score at least 12, 14, or 17 points based on your age group.
The submission deadline for the Qualification Round is 17 April 2026, 23:59 UTC+0
