Everything Astronomy continues to bring you fascinating insights from the world of astronomy, space science and more! This month our special guest speaker is Dr. Marian Selorm Sapah, a lecturer and research scientist at the Department of Earth Science, University of Ghana. Her research interests are focused on the areas of Cosmochemistry, Geochemistry, and Geoscience education. As a founding member of the Africa Initiative for Planetary and Space Science (AFIPS), she seeks to elevate Planetary and Space Science across the African continent, through cutting edge collaborative research, capacity building and outreach. Join us as Dr Marian introduces us to the world of Cosmochemistry!
The Henri Poincaré Junior Program of Côte d’Azur Observatory is open (deadline, October 31, 2019). This one proposes internships for international students wishing to perform a scientific training in one of the laboratories of the observatory. The laureates will receive up to 2200 euros for a training period of 2 months or more during the first half of 2020.
La prochaine fois que vous voyez une étoile filante, faites le voeux qu’on vous offre le livre qui vous fera découvrir ce qu’elles sont, et bien plus encore: comment reconnaitre météorites et cratères d’impact ! Et découvrir comment les impacts ont influencé l’histoire de notre planète et de la vie.
Bientôt disponible en libraire (10 Octobre)

We would like to draw your attention on the session 2f at the Goldschmidt Conference that will be held in Paris from 13 to 18 of August 2017.
02f: Mars – Early Differentiation and Dynamic Evolution
Convenors: David Baratoux, Vinciane Debaille
Keynote: Doris Breuer (DLR)
Geochemical and numerical models suggest that Mars evolved very rapidly after its formation with core segregation, mantle differentiation and crust formation following shortly after the planet’s initial accretion. This layered structure of crust, mantle and core, likely formed through an early magma ocean stage but was later modified by subsequent partial melting, crustal growth and differentiation. Isotopic variations in Martian meteorites (e.g. in 142Nd 182W) suggest the early formation of chemical heterogeneities in the mantle and their preservation until today. When and how did these reservoirs form and how could they survive to the present day? What were the major events affecting the chemistry of Mars and interior dynamics? What can be learned from studies of surface material and meteorites that document the major, trace and volatile element composition of magmas and fluids, the thermodynamic conditions (fO2, temperature, pressure) and timing of magmatic events? This session welcomes contributions based on remote sensing and Space mission observations, numerical models, in-situ or laboratory analyses and experimental data that explore the formation and evolution of chemical heterogeneities created in the early history of Mars and the subsequent dynamical and chemical evolution of this planet.
Abstract submission deadline is April 1st 2017 (23:59 CET). Please do not hesitate to forward this e-mail to your team.
We are looking forward to seeing you in Paris.
