The competition was conducted and evaluated over four days, consisting of 50% theory (5 hours), 10% telescope observation (1.5 hours), 15% planetarium observation (1.5 hours), and 25% data analysis (3 hours). The theory problems covered a wide range of topics including ▲basic concepts of astrophysics, ▲time and coordinates, ▲planetary and stellar systems, ▲cosmology, and ▲space technology. This year, 13 problems were presented, including the ‘Asteroid Deflection Experiment’ to change the orbit of an asteroid to protect Earth, and the ‘Laser Interferometer Space Antenna’ for gravitational wave detection. The telescope observation section included 4 problems such as ‘Measuring the angular velocity of Starlink satellites and calculating the distance between satellites.’ The planetarium observation section had 3 problems, including ‘Determining physical quantities of the exoplanetary system TRAPPIST-1.’ The data analysis section featured 2 problems, such as ‘Determining the mass of a newly discovered black hole through analysis of observational data on microlensing phenomena.’
