Surface melting in West Antarctica is triggered by atmospheric rivers that transport heat and moisture from the mid-latitudes and sub-tropics to the polar regions according to a new study from researchers [1] from the University Grenoble Alpes, CNRS, Sorbonne University, and from Portugal and the United Kingdom. Their study will be published in the journal Nature Geoscience on 28 october 2019.

The MEET project (Monitoring Earth Evolution Through Time) will receive 12.8€ over 6 years to investigate Earth’s evolution since its creation. The project is led by 3 researchers from 3 institutions in France, Germany and USA, and is held by the Université Grenoble Alpes’ Alexander Sobolev, professor at the ISTerre laboratory (OSUG - CNRS/IRD/UGA/USMB/IFFSTTAR).
This project will investigate two main questions: How has Earth’s chemical composition evolved over time? And what physical (...)

A team of astronomers led by Anne-Marie Lagrange, a CNRS researcher at the Institut de planétologie et d’astrophysique de Grenoble (OSUG - CNRS/Université Grenoble Alpes), has discovered a second giant planet in orbit around b Pictoris, a star that is relatively young (23 million years old) and close (63.4 light years), and surrounded by a disk of dust
The β Pictoris system has fascinated astronomers for the last thirty years since it enables them to observe a planetary system in the process (...)

Small enough to be an aircraft carry-on, the Juventas spacecraft nevertheless has big mission goals. Once in orbit around its target body, Juventas will unfurl an antenna larger than itself, to perform the very first subsurface radar survey of an asteroid.
ESA’s proposed Hera mission for planetary defence will explore the twin Didymos asteroids, but it will not go there alone: it will also serve as mothership for Europe’s first two ‘CubeSats’ to travel into deep space.
CubeSats are (...)

While testing a new subsystem on the SPHERE planet-hunting instrument on ESO’s Very Large Telescope, astronomers were able to capture dramatic details of the turbulent stellar relationship in the binary star R Aquarii with unprecedented clarity — even compared to observations from Hubble. This project involved researchers from IPAG / OSUG (CNRS, University Grenoble Alpes).
This spectacular image — the second instalment in ESO’s R Aquarii Week — shows intimate details of the dramatic stellar (...)

ESO’s exquisitely sensitive GRAVITY instrument has added further evidence to the long-standing assumption that a supermassive black hole lurks in the centre of the Milky Way. New observations show clumps of gas swirling around at about 30% of the speed of light on a circular orbit just outside its event horizon — the first time material has been observed orbiting close to the point of no return, and the most detailed observations yet of material orbiting this close to a black hole.
ESO’s (...)

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 (...)

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 (...)

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 (...)

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) — the gas- (...)
