Navigate a logical path from basics to advanced astrophysics. We cover the entire Olympiad syllabus with a focus on connecting distinct topics.
Move beyond formula sheets. We emphasize the physical reasoning and mathematical derivations essential for solving novel problems in competition.
High-quality illustrations and interactive diagrams transform abstract coordinate systems and celestial mechanics into clear, intuitive mental models.
A fast, distraction-free reading experience that's completely free. We utilize modern web tech to make learning as frictionless as possible.
Written by past Olympiad participants who understand the challenge. The guide evolves based on real feedback from the community.
Theory serves application. We integrate worked examples and problem-solving strategies specifically designed for the Olympiad format.
The foundation of observation. Coordinate systems, timekeeping, and spherical astronomy—everything needed to locate and track objects in the sky.
The science of measuring light. Understand magnitudes, filters, and indices, and how we quantify the energy received from distant celestial sources.
Gravity in action. From Kepler’s laws to orbital perturbations, master the dynamics that govern the motion of planets, satellites, and binary systems.
Inside the stars. A deep dive into stellar structure, nuclear energy generation, and the life cycles of stars from formation to compact remnants.
The large-scale universe. Study galactic structure and evolution, and explore the expansion history, composition, and fate of the cosmos.
Essential skills for the field. Data analysis, statistics, telescope techniques, and star charts for the observational component of the Olympiad.
Join a new generation of Olympiad scholars and enthusiasts who demand more than just notes.
Experience a guide built for depth, clarity, and true mastery.
