DESCRIPTION
The Sun formed from the local collapse of a dense molecular cloud 4.57 billion years ago. Some of the dust and gas from the molecular cloud remained in orbit around the forming Sun, constituting an accretion disk from which the planets and different solar system bodies have formed.
Although the main stages of the formation of the solar system are broadly understood, the detailed conditions of formation of the first solids and of the accretion and early evolution of planetesimals, as well as the chronology of events leading to the formation of the Earth and the other rocky planets remain largely unknown today. The physicochemical conditions prevailing within and at the surface of the young Earth, as well as the presence of liquid water, surely played a dominant role in the Earth’s early geodynamic evolution and, ultimately, in the emergence of life.
The main objective of this theme is to progress our understanding of what has made our solar system unique and, within it, the planet Earth. To this end, theme researchers develop approaches combining mineralogical, petrographic, chemical and isotopic studies of both terrestrial and extraterrestrial materials, analyses of remotely sensed data and experimental simulations. This work is conducted through both laboratory studies and the involvement of theme researchers in the exploration programmes of international space agencies.

Live event — “Après tout” (After all) (2020–2021), created by the company Présomption de presence (Presumption of presence)
A musical and choreographic play on the theme of the growth of the Earth, from its accretion, differentiation and the stabilisation of its outer layers, until the evolution of primitive life forms at its surface and the major extinctions. Multiple recent research projects of CRPG researchers (the age of chondrites, the evolution of the primitive atmosphere, the stabilisation of the continental crust, the origin of water on Earth) inspired the text presented during this choreographic concert.
