How numerical modeling helps decipher the dynamics and evolution of Venus

Diogo Lourenço, Cédric Gillmann and edited by Nuno Rodrigues January 22, 2025

Earth’s sister, Venus, is a planet whose evolution is drastically different from our own. Unravelling the hidden mysteries behind the divergent evolution of these two planets could hold the key to understanding what makes a planet habitable. Using numerical modelling, Diogo Lourenço and Cédric Gillmann unveil the dynamics of Venus while linking them to observations. In today’s blog pos ...[Read More]

Geodynamic modelling helps us understand Earth’s internal processes by providing a framework to test hypotheses. Analogue modelling uses physical models governed by the laws of nature, with resolution down to Planck’s length. In contrast, numerical modelling employs mathematical methods to approximate solutions to the physical laws governing Earth’s processes. Each modelling approach comes with it ...[Read More]
