Spring 2020 Undergraduate Courses

Thousands of planets have been discovered orbiting nearby stars. How many of these worlds can we expect to be Earth-like? We explore this question from the perspective of astronomers, geologists, and historians. We look back at Earth’s geologic history to periods when our planet itself would appear very alien to us today. We study the nearby planets Venus and Mars, which were once more Earth-like than today. We discuss not only the evolution of Earth, Venus, and Mars as habitable worlds but also how human understanding of these planets has evolved. Finally, we apply these perspectives to the search for alien Earths in our galaxy. This interdisciplinary treatment of Earth, its neighboring planets, and planets being discovered around nearby stars allows us to consider the potentially unique position of Earth as a habitable world not only in space but in time.

This course places the Earth and humanity in a broad cosmic context and seeks to answer fundamental questions about our surroundings. Where are we and where do we come from? What is matter made of and what processes created it? What are different types of stars like and where does our Sun fit in? What is the role of stars in shaping the cosmos and the planets orbiting them? How did the Sun, the Earth, and the other planets in the solar system form? What are the planets in the solar system like and are there other planetary systems like ours? In addition to exploring these questions, this course will help students to understand how we have arrived at our current view of the universe, with a focus on the scientific method and the history of astronomy.

Geologic processes and landforms on satellites and the terrestrial planets, their modification under various planetary environments, and methods of analysis. PTYS 411 is equivalent to GEOS 411 and HWRS 411 (cross-listed). PTYS 411 is required for the PTYS Minor.

This course discusses chemical thermodynamics and applies it to the origins and history of primitive planetary materials. The types of planetary materials will be discussed together with an overview of the chemical setting of their origins. We will discuss thermodynamic formalism, the various chemical pathways through which planetary materials are believed to have formed, the characterization and numerical methods we use to quantify such origins, and we will consider several case studies. May be co-convened with PTYS 513.
