In terms of medals, the Indian contingent was led by Prof. A. A. Deshpande (Retired from RRI, Bengaluru) and Prof.A. N. Ramaprakash (IUCAA, Pune), and there were four scientific observers: Prof. Durgesh Tripathi and Dr Akshat Singhal (IUCAA, Pune), Prof. SaritaVig (IIST, Thiruvananthapuram), and Dr Uttam Bhat (University of California, Santa Cruz). Dr Bhat is a former Astronomy Olympiad medallist himself.

This year, due to the prevailing COVID-19 pandemic, the IOAA was converted to a virtual competition where students from across 52 countries could participate online. A total of 298 students in 62 teams(including guest teams) from 52 countries participated in the competition. In terms of the number of students and teams, this was the biggest IOAA so far.

The competition consisted of a 5-hour theoretical examination, a 3-hour examination on data analysis, two software-based observational examinations for about 3 hours and one team competition for 3 hours. The theoretical questions covered a wide range of topics from celestial mechanics, binary stars, extra solar planets, astronomical telescopes and detectors, to even cosmic strings. The data analysis test focused on statistical techniques and graphing in the context of real astronomical data. The observational tests covered both the night sky and solar observations.

In a press release, HomiBhabha Centre for Science Education (HBCSE) of the Tata Institute of Fundamental Research (TIFR), which is the nodal centre in the country for Olympiads in Mathematics, Physics, Chemistry, Biology, Astronomy and Astrophysics and Junior Science, noted that this is India’s best-ever performance in IOAA.

The Olympiad programme is supported by the Department of Atomic Energy (DAE), Department of Science and Technology (DST), Department of Space(DoS), and the Ministry of Education (MoE) of the Government of India.
