Microbes and minerals may have triggered Earth’s oxygenation
In its early days, our Earth was poor in oxygen. And researchers are still wondering what caused our atmosphere to shift from this stable state to the equally stable one…
Huge intrusion into Earth’s crust could cause mega-earthquakes off Japan
Understanding the origin and the processes responsible for Japan’s strong seismicity is essential to protect the inhabitants of this region of the world. In this context, the structure and composition…

Is the Martian crust different from the Earth’s crust?
On a large scale, the internal structure of Mars appears quite similar to that of Earth. But what about in detail? The InSight mission to Mars provides us with details…
Earth’s center is cooling faster than previously thought
New thermal conductivity measurements suggest Earth is cooling faster than previously thought, suggesting that our planet’s tectonic activity may be coming to a halt sooner than expected. You will also…
The current continental crust differs from the primitive earth’s crust
At the very beginning, our Planet was only molten rocks. The cooling of its surface gradually formed the primitive continental crust which would allow to install the future favorable conditions…
