Fundamentals of Earth, Stars, and the Cosmos

Have you ever looked up at the night sky and wondered how the vast universe works? This course provides a comprehensive introduction to the fundamental concepts that define our place in the cosmos. By the end of this course, you will understand the scale and structure of the universe, grasp the life cycles of stars, and comprehend the major theories regarding cosmic origins and ultimate fate. What you'll learn: * Understand the foundational definitions of astronomy and cosmology, including key celestial mechanics. * Analyze the structure of our solar system, including the characteristics of Earth, planets, moons, and asteroids. * Trace the life cycle of stars, from stellar birth through sequence stages to their eventual collapse into white dwarfs or black holes. * Explore the organization of galaxies, nebulae, and clusters, and the concept of cosmic distance scales. * Learn the basic principles of modern cosmology, including the evidence for dark matter and dark energy. * Apply knowledge of gravity and relativity to understand theories regarding the formation and expansion of the universe. The course begins by defining core terminology and describing the components of our local solar neighborhood. It then progresses to cover stellar evolution, galactic structures, and the large-scale dynamics of the universe. This course is designed for absolute beginners with no prior knowledge of physics or astronomy. Start reading today to unlock the mysteries of space and time.
