[#Life in the Universe ... and much more] A new-generation #spectrograph called #ANDES will soon be installed on the #ESO's #ELT (Extremely Large Telescope).
Objectives: to analyze the atmosphere of Earth-like #exoplanets in search of signs of life, to analyze the chemical composition of distant objects in the young #Universe, to measure the acceleration of the #expansion of the Universe, and more.
[#RIP on the #Moon, #DORN ...] The lunar phase of the Chang'e6 mission comes to an end ...
The #regolith samples have been successfully collected. #DORN took the expected radon and polonium measurements for almost 23 hours - data analysis is already underway. The upper section of the Chang'e6 probe has re-launched from its base - heading for the lunar orbiter, leaving behind our instrument ...
Congratulations to the @cnes and IRAP teams who designed and operated DORN 👋
Waiting for [#JUICE ...] NASA's #Juno probe recently took images of the surface of #Europe, an icy moon of #Jupiter. And what a surprise! The #ice crust has shifted, distorted, ...
So what happened? Are these changes the result of interactions with the vast oceanic area lying beneath Europa's surface?
This discovery shows that these #sediments were formed in a river, a delta or near the shore of an ancient lake. It raises questions about #oxydation processes on Mars... and reinforces the hypothesis of past #habitability...
[#DORN : Objective #Moon] This Friday, May 3, at around 11 a.m., the Chang' E6 mission will lift off towards the Moon with the DORN instrument on board, designed at IRAP under the supervision of @cnes This mission marks the return of #France to the Moon!
Several stages will mark this mission: lift-off, placing in orbit around the Moon, lunar landing, commissioning of on-board instruments, return of samples to Earth.
[#HDR defense] of IRAP astronomer Sébastien Deheuvels this Monday morning. Topic: the #seismology of #subgiant and red giant stars.
Analysis of seismic data acquired by the #CoRoT and #Kepler space missions has enabled Sébastien Deheuvels and his team to revisit the problem of #chemical element transport and angular momentum in stars, measure the #internal rotation of sub-giants and red giants, detect the presence of #magnetic fields in stellar interiors, ...
RdV [#GrandPublic] L'ère du #NewSpace est arrivée ... Le Centre Spatial Guyanais (CSG) se meut en #PortSpatial destiné à accueillir de nouveaux opérateurs de lancement spatial. Marie-Anne Clair, ancienne directrice du CSG, en présentera les enjeux ce mardi soir.
RdV : 18h, Médiathèque José Cabanis, Toulouse
Organisateur : Académie de l'air et de l'espace - Air and Space Academy
[#FridayReading] Who are the 50 greatest contributors to our current knowledge of the #Sky and the objects that populate it? Who are the men and women who have made remarkable contributions to the development of #astronomy, #astrophysics, #planetology, #cosmology?
History of [#eclipses (3/3)] From now on, there's no need to wait for the next total #Sun#eclipse and to travel the globe to observe it: the development, on the ground and in space, of #coronography - a technique invented in 1931 by Bernard Lyot - makes it possible to reproduce this celestial phenomenon.
Histoire [#éclipses (2/3)] Ce lundi, une éclipse totale de #Soleil se produira au-dessus du continent nord-américain. La #couronne solaire sera alors visible à l'oeil nu et devrait ressembler à l'image ci-dessous, d'après les chercheurs du Predictive Science Inc.
Ces derniers ont conçu un #modèle 3D de la couronne solaire basé sur diverses données d'observation, au sol et dans l'espace - issues notamment de la sonde #SolarOrbiter de l'ESA.
[#ActuScience@IRAP ] A young IRAP PhD student formulates a new #theoretical model of the giant #magnetospheres of the planets #Jupiter and #Saturn: "By considering only the global motion of the #plasma (coming from the moons #Io and #Enceladus), it is possible to understand it simply as... a competition between various rotation resistances!"
[#SpaceSuccess] Following ESA's de-icing operation, the #Euclid satellite has gained 15% in optical sensitivity!
All satellites are assembled on Earth, in clean rooms whose humidity is close to 50°C. As it is propelled into space, its various components gradually cool down... and water condenses. To encourage evaporation, radiators have been installed in Euclid's instrument bay and the mirrors of the #telescope ...
@IRAP#JobOpportunity] We're recruiting a PostDoctoral Researcher in #Astrophysics as part of the European #RadioForegrounds+ program, which aims to provide the best possible characterization of the physical properties of polarized synchrotron galactic emissions and dust in the microwave domain.
[#ScienceNews@IRAP ] In 2029, the ESA and JAXA joint #CometInterceptor mission will take off from the Kourou Space Center aboard an #Ariane6. Objective: to study a #comet in its original state - or even an object of interstellar origin.
On March 5, @IRAP delivered the functional electrical model of the Low-Energy Electron Spectrometer (1 eV-1 keV) which is part of the #DFP (Dust, Fields, Particles) experiment. The future is on the way! 👍
