What do the blobs mean?

Seismologists work hard to provide the best snapshots of the Earth’s mantle. Yet tomographic models based on different approaches or using different data sets sometimes obtain quite different details. It is hard to know for a non specialist if small scale anomalies can be trusted and why. This week Maria Koroni and Daniel Bowden, both postdocs in the Seismology and Wave Physics group in ETH ...[Read More]

The Sassy Scientist – Analogue Modelling

The Sassy Scientist May 31, 2019

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. David asks: What do you think about analogue modelling? Dear David, Analogue modelling. Well, what’s not to like? Who doesn’t want to spend weeks or months fin ...[Read More]

The past is the key

Editorial Team 2 May 29, 2019

“The present is the key to the past” is a oft-used phrase in the context of understanding our planet’s complex evolution. But this perspective can also be flipped, reflected, and reframed. In this Geodynamics 101 post, Lorenzo Colli, Research Assistant Professor at the University of Houston, USA, showcases some of the recent advances in modelling mantle convection. Mantl ...[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]
