Abstract: The conditions of the early Earth are known to have been extreme and inhospitable, specifically temperatures were too high to retain any liquid water. The vast amounts of liquid water covering Earth’s surface today leads us to question where all this water came from. Until recently, the leading hypothesis was that smaller bodies from the outer reaches of the solar system could have collided with Earth and brought much of its water. However, recent studies show these small bodies are unlikely to have been the primary source of Earth’s water. In this lecture, I will explore an alternative hypothesis for the origin of Earth’s water inspired by observations of exoplanets. 

This talk is part of the evalutation and requirement for obtaining the title of docent at Lund University.

Coffee will be served from 14.15 outside the lecture room.
