“The Early Earth: Accretion and Differentiation” was writeen under the direction of James Badro, member of the team I6 “From dust to planets”, and of Michael J. Walter. The Early Earth: Accretion and Differentiation provides a multidisciplinary overview of the state of the art in understanding the formation and primordial evolution of the Earth. The fundamental structure of the Earth […]

The influx of extraterrestrial material onto Earth is well known through the fall of meteorites, such as the one which may have caused the dinosaurs’ extinction 65 Myr ago. However, the main amount of extraterrestrial material reaching the Earth (~40,000 tons/yr) comes from sub-millimetric particles, called interplanetary dust particles and forming the cosmic dust, which generally originate from asteroid collisions […]

On February 11, 2016 at 16:30, the Ligo and Virgo collaborations announced they had detected gravitational waves, a century after its description by Einstein. It’s a double masterstroke: by detecting for the first time these waves, the researchers also observed the first collision of two black holes. A new window opens on the Universe. Numerous scientists participated in this project. […]
