India finishes joint third at the Hanoi astronomy olympiad with four golds and a silver

All five Indian students at the 19th International Olympiad on Astronomy and Astrophysics came home with a medal. Pranjal Dixit of Hyderabad, Sumant Gupta of Delhi, Akshat Srivastava of Gurugram and Arnav Sehrawat of Faridabad took gold. Harshil Amitkumar Patel of Vadodara took silver. The contest ran in Hanoi from 25 September to 5 October. India finished joint third with the host, Vietnam. Iran and South Korea led, each with five golds.

The Homi Bhabha Centre for Science Education, a national centre of the Tata Institute of Fundamental Research in Mumbai, announced the table. HBCSE is the body that selects and trains the Indian teams for the science olympiads. NDTV put the field at 307 students from 64 countries, the largest IOAA so far. The papers covered theory and observation.

The five names and the table

The medal list is short enough to keep intact. Dixit, Gupta, Srivastava and Sehrawat are the golds. Patel is the silver. Four of the five study in school systems around Delhi and Hyderabad. Patel is the Gujarat name on the sheet. India did not have a student outside the medals. Iran and South Korea did one better: five golds each, a clean team score. Vietnam matched India's four-and-one.

Joint third is a placement, not a points mystery. When two teams sit on the same gold count, the table ties them. HBCSE did not publish a tie-break that would have split India and Vietnam. The public fact is the medal count: four gold, one silver, third alongside the host, behind two teams that swept.

A first since 1989, with a limit on what it means

HBCSE added a wider claim that is easy to overread. With IOAA done, every senior olympiad of the year is closed: mathematics, physics, chemistry, biology and astronomy. Every Indian student in those contests won either gold or silver. The centre counted 16 golds and 8 silvers. It said this was the first time that had happened since India began sending students to the international olympiads in 1989.

That sentence is about medals, not about rank. A team can medal in full and still finish behind a sweep, which is what India did in Hanoi. The five-year astronomy note from HBCSE is in the same key: in the last five years every Indian IOAA student has won gold or silver, 64 percent gold and 36 percent silver. The 2026 team sits inside that run, four-fifths gold.

The 1989 line is the part worth keeping. India has sent students to these contests for 37 years. A year in which none of the senior teams brought home a bronze, or a blank, had not occurred before, on HBCSE's count. Sixteen golds and eight silvers across five subjects is the figure. It does not say India topped any one of those five tables. Iran and South Korea topped this one.

What the contest actually tests

IOAA is not a quiz. The observation paper puts students on instruments and on the sky, and the theory paper asks them to work problems in astrophysics under a clock. A gold in Hanoi means a mark high enough, against 307 students from 64 countries, to clear the gold cut. The Indian team cleared it four times and missed it once, by a silver. That is a different fact from a press line about podium finishes.

The open question is what HBCSE does with the run. A first clean gold-or-silver year since 1989 will be cited the next time the centre asks for training money and camp slots. The Hanoi result supplies the astronomy piece of that ask: four named golds, one named silver, joint third, and two teams still ahead with perfect gold sets.
