Exoplanets and Origins of Life

Lecturer: Prof. Dr. Brice-Olivier Demory

ECTS: 4
Semester: HS 2025-2026
Lectures and Exercises: TBA

Description

How did life begin on Earth, and could it exist elsewhere in the universe? This course brings together insights from biology, chemistry, geology, and astrophysics to explore these fundamental questions. We begin by examining the origins and evolution of life on our planet. Next, we turn to exoplanets—worlds orbiting other stars—discussing their properties and the methods used to detect and study their atmospheres. Finally, we explore ongoing research efforts in Bern and beyond to search for signs of life within and outside our Solar System.

Learning outcome

Upon successful completion of this course, participants will have a comprehensive understanding of the formation of stars and planets, as well as the processes that deliver essential chemical elements necessary for the building blocks of life. They will be familiar with the vast diversity of microorganisms and the key differences between them. The course will also provide insights into the various theories surrounding the emergence and evolution of life on Earth, highlighting how chemical, geological, and biological factors are interconnected.

Participants will be able to explain the synthesis of complex molecules in the relevant astrophysical and planetary contexts and understand the fundamental principles of exoplanet formation and evolution. They will gain knowledge of the different techniques used to detect and characterize exoplanets and develop problem-solving skills related to both the origins of life and exoplanetary science. Additionally, they will have the opportunity to design and carry out a small research project, working with research articles, field data, or real observational datasets, such as those from NASA and ESA’s James Webb Space Telescope (JWST).
