A research group has focused on the fault segmentation issue, aiming at testing if one could evidence intrinsic parameters controlling lateral strike-slip fault geometry.
The Cassini-Huygens mission made many discoveries about Saturn and its many satellites, the largest of which is Titan. During its descent into Titan's atmosphere in January 2005, the Huygens module identified a dendritic network of rivers incising a hill near the landing site, similar to the networks observed on Mars and Earth.
For the first time, a team has succeeded in characterizing, in a liquid medium and at the nanometric scale, the influence of bacterial cells and the organic polymers they secrete on the formation of a mineral.
This effect violates elementary rules governing the distribution of isotopes during chemical reactions. It could be relevant for many chemical elements and be part of some well-known isotopic variations, identified in the components of meteorites, and generally considered to reflect stellar nucleosynthetic processes.
Earth’s atmosphere is made up of 78% nitrogen and 21% oxygen, a mixture that is unique in the Solar System1. The oxygen was produced by some of the first living organisms. But where did the nitrogen come from? Did it escape from Earth’s mantle through volcanic activity?
A team of researchers from IPGP, Université de Paris, CNRS and the MNHN, published in the last months, a series of three papers that contribute to explain the formation of the first minerals of our Solar System. In order to better convey the relevance of this study, they publish a video illustrating their work.
A new lava flow was identified and first seafloor images of the volcano were taken during MAYOBS 3 and MAYOBS 4 oceanographic campaigns. Meetings and feedback with the various stakeholders in Mayotte also took place on board the Marion Dufresne.
Nathalie Feuillet, a researcher at the Institut de physique du globe de Paris, head of the INSU TELLUS SISMAYOTTE project and co-head of the MAYOBS 1 mission, answered three questions about on the operations that led to the discovery of a new active volcano east of Mayotte.
The IPGP's Guadeloupe Volcanological and Seismological Observatory participates, on Monday 3 and Tuesday 4 June, in the Japanese days organised by the Prefecture of Guadeloupe with all partners involved in telluric risk management.
A team of researchers from IPGP and JPL reveals that strong insights into Mars’ thermal history and rheology can be gained by considering Mars’ closest satellite, Phobos, whose orbital evolution is governed by Mars’ thermo-chemical history, through tidal interactions.
On March 2, 2019, the Trace Gas Orbiter Probe (TGO) of the European Space Agency's ExoMars program was able to photograph the InSight probe on the surface of the red planet. This is the first time that a European satellite has achieved this technical feat.
From 23 February 2019, land and sea missions, coordinated by the CNRS, will try to shed light on the mechanisms related to the many earthquakes recorded off Mayotte since May 2018.
