Planetary Formation: From Cosmic Dust to Habitable Worlds

Have you ever wondered how our planet formed, or what makes an exoplanet truly Earth-like and potentially habitable? This course provides a foundational scientific understanding of planetogenesis, focusing on the physical and chemical requirements for creating terrestrial worlds. By the end of this course, you will be able to trace the complex journey of matter from a protoplanetary nebula through the stages of accretion, differentiation, and atmospheric development, focusing on the conditions required for rocky planet formation. What you'll learn: * Understand the physics and chemistry of protoplanetary disks and the initial conditions for planet formation. * Learn the stages of planetary accretion, from dust coagulation and planetesimal growth to large-scale planetary embryos. * Apply models of planetary differentiation, including core formation, mantle dynamics, and crust development in rocky worlds. * Analyze the critical role of atmospheric degassing and surface water condensation in creating an ocean world. * Practice classifying and characterizing terrestrial planets and exoplanets based on their compositional and physical properties. The course begins with foundational concepts of stellar nurseries and nebular gas composition before moving step-by-step through the physical mechanisms that build planets, concluding with the crucial factors for developing long-term habitability. This course is designed for absolute beginners interested in planetary science, astrophysics, or geology. No prior scientific knowledge or complex mathematics is required.
