Habitable Worlds

Are we alone in the Universe? If so, why? If not, where are our cosmic cousins? Such questions, once the domain of science fiction, are on the verge of being answered with science facts. Astronomers are discovering planets around other stars. Planetary scientists are exploring the worlds in our solar system. Biologists are unlocking the secrets of metabolism and evolution. Geoscientists are determining how the Earth supports life. And as we struggle to build a sustainable future for ourselves, all of us are finding out how technologically advanced civilizations rise and how they might fall.

Inspired by this ongoing scientific revolution, Habitable Worlds surveys key concepts from across the major areas of science that help us to understand what makes Earth - or any other planet - a habitable world.

Course Format

  • Habitable Worlds is an innovative course with a format different from most online courses. It is built around interactive activities with rich adaptive feedback. These are not videos or simple readings and quizzes. Usually they are problem-solving activities through which you will be introduced to key concepts, and master them, in a question-driven 'learn-by-doing' approach. Often they will be designed around game-like simulations that you can manipulate, or virtual field trips that you can explore. In some ways, these activities can feel like a serious game! That's not an accident: That's in fact how the pursuit of science feels to professional scientists.

What you’ll learn

  • Explain the conditions that can make a planet habitable.
  • Identify and justify the steps necessary to determine if an exoplanet is habitable.
  • Describe the history of Earth as an inhabited world and how this knowledge informs the search for life on other worlds.
  • Describing and interpreting observations using data analysis, foundational mathmatics, and accessible computational methods.
  • Applying scientific reasoning, particularly using hypothesis-driven processes to create scientific models, testing models using basic qualitative and quantitative reasoning, choosing among competing ideas that have different levels of uncertainty.
  • Applying problem-solving skills including breaking complex problems into multiple steps, identifying the knowledge needed to solve each step, and obtaining and interpreting that knowledge quantitatively and qualitatively.
