Introduction
AstroChallenge is an annual astronomy competition jointly organised by the Astronomical Societies of National University of Singapore and Nanyang Technological University. The competition is specially tailored for students in Secondary Schools, Junior Colleges and Polytechnics. Students will be exposed to a comprehensive array of questions that range from theoretical to practical astronomy.
Our Signature Event
Astrochallenge is hosted over the span of a few days and challenges participants in all aspects of Astronomy: from theoretical papers to night sky observation techniques.
The competition consists of multiple rounds, but the main event is split between two sessions: Day 1 and Day 2. The first day consists of the Individual Paper, followed by the Team Round, and finally the Observation Round in the evening. The second day is the Finals, where we crown the new champions of Astrochallenge!
