India has once again proven its scientific brilliance on the global stage. At the 18th International Olympiad on Astronomy and Astrophysics (IOAA 2025), held in Mumbai from August 11 to 21, 2025, the Indian national team delivered a spectacular performance, securing four gold medals and one silver medal. This stellar achievement reaffirms India’s growing leadership in science education, astronomy, and international Olympiad excellence.

A Historic Edition of IOAA – Hosted in India for the First Time

The IOAA 2025 holds a special place in history as it was the first time India hosted the prestigious event, and it turned out to be the largest edition since its inception in 2007. Nearly 300 high-school students from 64 countries participated, including 12 countries competing for the very first time. The scale, diversity, and enthusiasm made IOAA 2025 a true global celebration of scientific talent, collaboration, and youth-driven innovation.

The Olympiad brought together some of the brightest young minds who competed across theoretical, observational, and data analysis rounds, testing their knowledge and problem-solving skills in astronomy and astrophysics.

India’s Medal Tally at IOAA 2025

The Indian team, trained under the Homi Bhabha Centre for Science Education (HBCSE), Tata Institute of Fundamental Research (TIFR), made the nation proud by winning five medals in total:

• Gold Medalists

  • Aarush Mishra (Bengaluru)

  • Akshat Srivastava (Kolkata)

  • Banibrata Majee (Delhi)

  • Panini (Patna)

• Silver Medalist

  • Sumant Gupta (Gurugram)

These students were mentored by Prof. Jasjeet Singh Bagla and Dr. Harvinder Kaur Jassal from IISER Mohali, who guided them through a rigorous training and selection process, starting with an intensive orientation-cum-selection camp earlier this year.

Global Competition: A Showcase of Scientific Excellence

The IOAA 2025 was not only a proud moment for India but also a testament to global scientific talent. A total of 50 gold, 44 silver, 51 bronze medals, and 26 honourable mentions were awarded across participants from all over the world.

The Iranian team made headlines by achieving a rare and remarkable feat – winning gold medals in all five of their slots, setting a new benchmark for academic excellence.

Despite such tough global competition, India’s four golds and one silver solidified its position as one of the top-performing countries in the Olympiad.
