Stellar storms modify the atmospheric evolution of planets. ‘Hot Jupiter’ planets being very close to their host star, are often affected by such storms. In this week’s peculiar planet, Gopal Hazra, a post-doctoral fellow at the School of Physics, Trinity College Dublin, discusses effect of stellar storms on those planets using his self-consistent hydrodynamic models of planetary ...[Read More]
It is the smallest planet of the Solar System, the closest to the Sun and the quickest at orbiting around it, the one with the least inclined and most elongated orbit, the only one where a day lasts two-thirds of a full year, the one with the highest bulk density. Mercury is a planet of extremes, but rarely visited by space missions (compared to Mars, Venus and the Moon). This week Dr. Nicola Tosi ...[Read More]
After many (attempted) visits to Venus in an earlier era of space exploration, the focus of terrestrial planet science was shifted towards e.g. our other neighbour Mars. Yet, lately, Venus seems to gain scientific popularity and not without reason – there remains so much to figure out about the puzzling planet. The virtual mini-workshop ‘Venus Science Today’ was held a few weeks ago to bring toget ...[Read More]
This week on the GD Blog we are taking a magical geodynamicist’s mystery tour to our planet’s Moon thanks to Tobias Rolf, Researcher at the Centre for Earth Evolution and Dynamics (CEED) at the University of Oslo, Norway (currently a Visiting Researcher at the Institute of Geophysics at the University of Münster, Germany). Imagine you are orbiting the Earth at an altitude of a few hun ...[Read More]
How can geoscience methods be incorporated into the research of extrasolar planets? These are planets that are beyond our own solar system and their geological properties are mostly unknown. Kaustubh Hakim is a postdoctoral researcher at the Center for Space and Habitability in Bern, Switzerland where he studies the interiors of rocky exoplanets and geochemical cycles using theory and lab experime ...[Read More]
This week, Caroline Dorn, Ambizione Fellow at the University of Zurich, tells us her view on space travel and why we shouldn’t pack our bags just yet. Space exploration is experiencing a new boom, a come-back since the 60s & 70s! First discoveries of planets outside our solar system in the 90s have set the foundations of a new discipline that is exoplanet science – the field in wh ...[Read More]
Every week, The Sassy Scientist answers a question on geodynamics, related topics, academic life, the universe or anything in between with a healthy dose of sarcasm. Do you have a question for The Sassy Scientist? Submit your question here or leave a comment below. After a distraught period (of more than a decade!) since the news first came out that Pluto was not considered a true planet anymore, ...[Read More]
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]
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]
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 move back to our own solar system. Many of us will clearly remember the downgrading of Pluto as a planet nearly 12 years ago to the month. In this informative and witty post, Laurent Montesi from the Univers ...[Read More]
