Astronomy

Astronomy explores the fundamental principles of the universe, focusing on the lifecycle of stars, the structure of our solar system, and the dynamics of the Sun-Earth-Moon system. In this course, students learn about the analysis of starlight spectra and brightness to determine the composition, movement, and distance of stars. Kepler’s laws are examined to explain the motions of orbiting celestial bodies and the factors that influence their paths. Students will also learn how the cyclical changes in Earth’s orbit and axial orientation affect climate over geological time scales. Additionally, students will build on their geological knowledge by studying extraterrestrial objects, such as lunar rocks and meteorites, to gain insights into Earth's formation and history.
