First Successful Test of Einstein’s General Relativity Near Supermassive Black Hole

Publié le 26 juillet 2018
Press release published by CNRS/UGA/Observatoire de Paris/Université Sorbonne/Université Paris Diderot

Observations of the Galactic Centre team at the Max Planck Institute for Extraterrestrial Physics (MPE) have for the first time revealed the effects predicted by Einstein’s general relativity on the motion of a star passing through the extreme gravitational field near the supermassive black hole in the centre of the Milky Way.
This long-sought result represents the climax of a 26-year-long observation campaign using ESO’s telescopes in Chile.
Obscured by thick clouds of absorbing dust, the (...)

Planck : final data from the mission lends strong support to the standard cosmological model

Publié le 17 juillet 2018
Press release published by CNRS / CNES

Our Universe would be well constituted to 95% of matter and dark energy whose nature remains unknown.
In 2013, ESA’s Planck mission unveiled a new image of the cosmos : an all-sky survey of the microwave radiation produced at the beginning of the Universe. This first light emitted by the Universe provides a wealth of information about its content, its rate of expansion, and the primordial fluctuations in density that were the precursors of the galaxies. The Planck consortium publishes the (...)

First Confirmed Image of Newborn Planet Caught with ESO’s VLT

Publié le 2 juillet 2018
Press release published on July 2, 2018 by ESO

SPHERE, a planet-hunting instrument on ESO’s Very Large Telescope, has captured the first confirmed image of a planet caught in the act of forming in the dusty disc surrounding a young star. The young planet is carving a path through the primordial disc of gas and dust around the very young star PDS 70. The data suggest that the planet’s atmosphere is cloudy.
Astronomers led by a group at the Max Planck Institute for Astronomy in Heidelberg, Germany have captured a spectacular snapshot of (...)

ALMA Discovers Trio of Infant Planets around Newborn Star

Publié le 18 juin 2018
Press release published on june 13, 2018 by the ESO and CNRS

Two independent teams of astronomers have used ALMA to uncover convincing evidence that three young planets are in orbit around the infant star HD 163296. Using a novel planet-finding technique, the astronomers identified three disturbances in the gas-filled disc around the young star : the strongest evidence yet that newly formed planets are in orbit there. These are considered the first planets to be discovered with ALMA.
The Atacama Large Millimeter/submillimeter Array (ALMA) has (...)

ICE MEMORY : new drilling operations in Russia

Publié le 28 mai 2018
Press release published by the Fondation Université Grenoble Alpes

Collecting ice cores from glaciers most at risk from climate change and storing them in Antarctica for future generations of scientists : that is the goal of ICE MEMORY, an international programme aimed at preserving the climate and environmental memory of glaciers.
Following the two successful drillings in the Col du Dôme glacier in French Alps in August 2016 and on the Illimani glacier in Bolivia in June 2017, two further drilling expeditions will be conducted in Russia in May and June (...)

Intermittent rivers affect global CO2 emissions

Publié le 21 mai 2018
Press release published by Irstea / UGA

The results of the first global study of the contribution that intermittent rivers make to carbon cycling
A collaborative study involving 94 international partners was led by researchers from IRSTEA, the Laboratoire d’écologie alpine / OSUG (LECA) , the University of the Basque Country and the Leibniz-Institute of Freshwater Ecology and Inland Fisheries. This research, published on May 21st in Nature Geoscience, represents the first global study of the contribution that intermittent rivers (...)

Similar evolutionary paths in the domestication of goats and sheep

Publié le 6 mars 2018
Press release published by UGA/CNRS/USMB

By comparing the genome changes observed in goat and sheep, researchers has taken the first step towards characterising the genetic basis underpinning the ‘domestication syndrome’.
During domestication processes, humans have shaped the characteristics of wild species in order to exploit them. The genetic mechanisms behind induced changes are still poorly understood to this day, including those that would explain the occurrence of similar traits in different domestic species. However, by (...)

First discovery of an exoplanet by SPHERE

Publié le 7 juillet 2017
Press release published by the CNRS

The astronomical instrument SPHERE, installed since 2014 on the Very Large Telescope (VLT) of the European Southern Observatory (ESO) in Chile, has made its first discovery of a planet around a star other than the Sun, known as an exoplanet.
Only a handful of the 3,600 exoplanets detected since 1995 have been observed directly in this way. With a mass between 6 and 12 times that of Jupiter, HIP65426b is a young massive planet orbiting around a bright star in rapid rotation, located in the (...)

Ice Memory 2 : full success on the Illimani glacier

Publié le 20 juin 2017
Press release published by the Fondation univeristé Grenoble Alpes

The second expedition of the ICE MEMORY project, took place on the Illimani glacier (Bolivia) from May 22nd until June 18th, 2017. It just ended with full success ! The international team at work has successfully extracted two ice cores down to bedrock, at more than 6,300 m above sea level, despite extreme climatic conditions. One of the ice cores will be analyzed while the other one with join the first world heritage vault of ice cores (in Antarctica) obtained from glaciers under threat (...)

The Earth’s core in motion like nothing you’ve seen before !

Publié le 4 juin 2017
Press release published by CNRS / CNES the CNRS

A shield that protects us from solar wind, the Earth’s magnetic field is used as a bearing for airplanes, spacecrafts and even deep-well drilling. A better understanding of the physics behind our planet’s magnetic field, shaped in the outer core 3,000 km beneath our feet is therefore essential.
Like many planets and most stars, Earth produces its own magnetic field, primarily through a dynamo effect caused by the movement of an electrically conducting fluid – in this case, a mix of melted (...)
