The International Olympiad on Astronomy and Astrophysics (IOAA) is a prestigious global competition held annually in a different host country. It challenges participants in both theoretical and practical aspects of astronomy and astrophysics. The theoretical section examines various topics, including cosmology, space technologies, coordinates and times, and solar and stellar systems. Meanwhile, the practical section focuses on observations and data analysis, which may involve the use of astronomical instruments or software.
Participants compete in teams led by a professional astronomer or teacher as their team leader. Given the international scope of the IOAA, students must enter through their respective National Olympiad Committees. You can review previous exam papers to get a better grasp of the content and level of difficulty!

The International Astronomy and Astrophysics Competition (IAAC) is a prestigious online contest that allows participants to engage from the comfort of their homes. This competition is structured in three levels: the qualification round, the pre-final round, and the final round. In the qualification round, participants tackle five astronomy problems. Successful participants then move to the pre-final round, which involves solving six problems, including two research-based problems that necessitate reading scientific papers. Lastly, the final round is a multiple-choice exam that tests comprehensive knowledge of astronomy and astrophysics.
To advance through each level, participants must achieve a specific number of points. The questions range from general knowledge to complex astrophysical calculations, requiring a fundamental understanding of the subject. Reviewing past competitions and their solutions can provide valuable preparation and insight into the types of problems encountered in the IAAC.
3. International Space Olympiad

Fee: $15 entry fee, which can be waived in certain cases
The NSS Gerard K. O'Neill Space Settlement Contest, organized annually by the National Space Society (NSS), focuses specifically on designing viable space settlements. Unlike broader science competitions, this contest challenges students to develop practical solutions for human habitation beyond Earth.
Participants must consider a variety of factors, including engineering, agriculture, economics, and social dynamics, to create comprehensive space settlement designs. This interdisciplinary approach ensures that students explore multiple areas to complete their projects effectively. Participants can enter the contest either individually or as part of a team, and submissions are categorized by age group.
For those interested, a list of helpful resources is available to assist throughout the design process.
5. International Astronomy Olympiad

Competition dates: November to February
Location: Online
Fee: Free
If you have an interest in computer programming and space exploration, consider participating in this competition, which focuses on the practical applications of coding in space. Working in teams, you will develop a Python program to solve a specified scientific task, which is then executed on the International Space Station (ISS). The 2023-24 edition challenge requires students to create a program that utilizes the Astro Pi computers on the ISS to collect data and calculate the station's speed.
The competition is divided into several phases, including idea submission, programming, and deployment on the ISS. At each stage, select teams advance to the next level. With over 700 teams registering last year and only 10 winning, the competition is highly competitive. Participating will teach you about the ISS's operations and provide hands-on experience in data analysis and computer program troubleshooting.
7. Regeneron International Science and Engineering Fair (ISEF)
Eligibility: All high school students (even international students can apply)
Prize: Cash prizes with the top winner receiving $75,000. Additional prizes could include scholarships, internship opportunities, lab equipment and more
Competition dates: Regional/local fairs usually conclude by April, ISEF takes place over one week in the month of May
Location: Los Angeles (location varies by year)
Fee: Ideally, any costs will be covered by the fair/organization through which you get accepted to the ISEF
Unlike the other competitions listed, the International Science and Engineering Fair (ISEF) evaluates students based on their research projects. Participants can work individually or in teams, and their research must align with the competition’s categories, one of which includes astronomy and cosmology. The program emphasizes thorough research, and participants are judged on their scientific inquiry, execution, and both virtual and physical presentations.
It's important to note that to qualify for ISEF, students must first participate in a regional or local fair. Although this preliminary step may seem daunting, the prestige of the competition makes it worthwhile. If you’re interested, you can look at our blog, which covers ISEF in detail!
8. US Invitational Young Physicists Tournament (USIYPT)
Application deadline: January 10, 2024
Eligibility: All high school students, even international ones, can form teams of 2-4 people. All team members must be from the same school.
Competition dates: February 3, 2024 – February 4, 2023
Location: North Carolina State University, Raleigh, NC
Fee: $1000 per team (this covers registration, membership fees, three nights’ hotel stay, meals, and local transport. International travel is not included in this)
Hosted by the United States Association for Young Physicists Tournaments (USAYPT), a non-profit organization, the USIYPT is a unique physics research and debate competition. Teams of four students are tasked with developing solutions to four challenging problems and then presenting and defending their solutions in 'physics fights'—debate-style events where they argue their solutions against those of opposing teams.
While the competition covers a broad spectrum of physics topics, past problems have often included elements of astronomy. For example, previous tournaments have included tasks such as creating a three-dimensional map of the moon’s surface, measuring the length of one Astronomical Unit, and investigating the physics behind non-water rainbows.
