Mumbai, August 23, 2025 — India has achieved a remarkable feat at the 18th International Olympiad on Astronomy and Astrophysics (IOAA) 2025, securing four gold medals and one silver, earning the nation an overall Rank 1. Hosted in Mumbai from August 12 to 21, 2025, this prestigious global competition saw nearly 300 high-school students from 64 countries compete in a series of rigorous challenges in theoretical astronomy, observational skills, and data analysis. This marks the first time India hosted the IOAA, making the victory a historic milestone for the country’s scientific community.

A Stellar Performance by Indian Students

The Indian team, trained under the Homi Bhabha Centre for Science Education (HBCSE), a national centre of the Tata Institute of Fundamental Research (TIFR), demonstrated exceptional prowess. The gold medalists were Aarush Mishra from Bengaluru, Banibrata Majee from Delhi, Panini from Patna, and Akshat Srivastava from Kolkata. Sumant Gupta from Gurugram clinched the silver medal. Mentored by Prof. Jasjeet Singh Bagla and Dr. Harvinder Kaur Jassal from IISER Mohali, the team underwent intensive training following a competitive selection process earlier this year.

The IOAA 2025, held at various venues in Mumbai, challenged participants with complex problems designed to test their understanding of astronomy and astrophysics. India’s students excelled across all categories, showcasing the strength of the nation’s STEM education system. Their performance placed India among the top-performing nations, with the Iranian team also standing out by securing gold medals for all five of its participants.

A Global Stage for Scientific Excellence

The 18th IOAA was the largest in its history, with 12 countries participating for the first time, adding to the event’s diversity and competitive spirit. A total of 50 gold, 44 silver, 51 bronze medals, and 26 honorable mentions were awarded during the grand closing ceremony at the Nita Mukesh Ambani Cultural Centre (NMACC) in Mumbai. The event was attended by distinguished dignitaries, including Dr. Anil Kakodkar, Chancellor of the Homi Bhabha National Institute, Dr. Ajit Kumar Mohanty, Secretary of the Department of Atomic Energy, and Prof. Dipankar Banerjee, Director of the Indian Institute of Space Science and Technology.

Dr. Kakodkar praised the young scientists, stating, “Students should continue to explore the frontiers of science with curiosity and commitment.” He emphasized India’s growing investments in observational astronomy and gravitational wave research, highlighting the nation’s commitment to advancing space science.

IOAA 2025: A Celebration of Science and Culture

Organized by HBCSE, the IOAA 2025 was not only a platform for academic excellence but also a celebration of global collaboration and cultural exchange. Participants enjoyed performances showcasing India’s rich art, music, and heritage, adding a unique dimension to the event. The Olympiad, established in 2007, continues to inspire high-school students worldwide to pursue careers in astronomy and astrophysics.

India’s success at IOAA 2025 underscores its rising prominence in global science education. The achievements of Aarush Mishra, Banibrata Majee, Panini, Akshat Srivastava, and Sumant Gupta serve as an inspiration for young minds across the country, proving that dedication and rigorous training can lead to excellence on the world stage.

Looking Ahead

This victory reinforces India’s position as a hub for scientific innovation and talent. As the nation continues to invest in space research, with upcoming missions like Aditya-L1, India’s first space-based solar observatory, the success at IOAA 2025 signals a bright future for Indian astronomy. The event has ignited a passion for STEM among students, encouraging the next generation to reach for the stars.
