Le mercredi 14 mars, Dr. Vinciane Debaille (Département des Sciences de la Terre et de l’Environnement, Université Libre de Bruxelles) a donné une conférence intitulée « Meteorites in Antarctica: archives of our solar system » à l’Université de Cambridge. Elle a été accueillie par le Dr. James Bryson (Department of Earth Sciences , University of Cambridge).
Abstract
Every day, several tons of extraterrestrial material fall on Earth, most of it as unnoticed dust. Sometimes larger blocks survive their entry into the atmosphere and can be found as meteorites. Some of them represent the starting blocks of our solar system while others sample remote asteroids, and even planets such as Mars. We will see how we can try to understand the formation and evolution of our solar system thanks to them. We will also see how these space rocks arrive on our planet and how they are collected on Earth, notably in Antarctica.
