Astrobiology - an Overview

PD Dr. M.Kissler-Patig (LMU & ESA) - contact: mkissler@esa.int

November 20-24, 2023

Overview:

The lecture aims at providing a first overview of the broad field of Astrobiology. It will briefly cover pre-biotic chemistry and the origins of life, will look at Earth as a habitable planet and follow the co-development of its atmosphere and life on Earth. We will then explore our Solar system and look at the possibilities of life on Mars, on Titan and other Moons of Giant Planets. We will review our current knowledge on exoplanets, their properties and their atmospheres in the context of biosignatures. The lecture will finish with some thoughts on extra-terrestrial intelligence and alien biochemistry.
Throughout the lectures, we will point out which groups in Garching contribute to various aspects of this vast field; and show which ground- and space-based facilities are (becoming) available for this research.

Structure:

The lecture will be structured in five days with 2h lecture before lunch, 1h after lunch. Homework will be in form of videos to watch and articles to read over the week.
