The geodynamics of Enceladus: exotic and familiar


This week, Gael Choblet, CNRS research associate in the Laboratoire de Planétologie et Géodynamique (University of Nantes and Angers), tells us everything about the interior of Enceladus, an interesting icy moon of Saturn! This is my first contribution in these pages. The choice of Saturn’s small moon Enceladus as a topic mostly results from my acquaintance with this planetary body. Yet, the reade ...[Read More]

Iron volcanism on metallic asteroids?

Metallic asteroid

This week, Francis Nimmo, professor in the Department of Earth and Planetary Sciences (University of California Santa Cruz), tells us about volcanism on metallic asteroids! Around and after the formation of the solar system (4.5 billion years ago onwards), volcanoes on some of the gigantic bodies of the asteroid belt might have erupted … iron. Explanations. One way in which we can learn abou ...[Read More]

Geodynamics in Planetary Science

Geodynamics in Planetary Science

It is a question that humankind has been asking for thousands of years: Are we alone in the Universe or are there other worlds like our own? As of today, it is unknown whether or not inhabited planets exist outside of our own solar system. With the discovery of the extrasolar planet 51 Peg b in 1992, it was confirmed that our sun is not the only star that hosts planets and therefore the search for ...[Read More]

Oceans on Mars: the geodynamic record

Oceans on Mars: the geodynamic record

Apart from our own planet Earth, there are a lot of Peculiar Planets out there! In this series we take a look at a planetary body or system worthy of our geodynamic attention, and this week we are back to our own solar system, more precisely to our neighbour Mars. In this post, Robert Citron, PhD student at the University of California, Berkeley, writes about the links between oceans, shorelines, ...[Read More]
