Ammonia-rich hail sheds new light on Jupiter's weather
Ammonia-rich hail sheds new light on Jupiter’s weather
New Juno results suggest that the violent thunderstorms taking place in Jupiter's atmosphere may form ammonia-rich hail, or 'mushballs', that play a key role in the planet's atmospheric dynamics. This theory, developed using data from Juno's microwave radiometer by the Juno team, is described in two publications led by a researcher at the Laboratoire Lagrange (CNRS/Observatoire de la Côte d'Azur/Université Côte d'Azur) with support from the CNES.

Unprecedented ground-based discovery of two strongly interacting exoplanets
Unprecedented ground-based discovery of two strongly interacting exoplanets
Several interacting exoplanets have already been spotted by satellites. But a new breakthrough has been achieved with, for the first time, the detection directly from the ground of an extrasolar system of this type.  An international collaboration including CNRS researchers 1 has discovered an unusual planetary system, dubbed WASP-148, using the French instrument SOPHIE at the Observatoire de Haute-Provence (CNRS/Aix-Marseille Université) .

Quasar jets are particle accelerators thousands of light-years long
Quasar jets are particle accelerators thousands of light-years long
An international collaboration bringing together over 200 scientists from 13 countries has shown that the very high-energy gamma-ray emission from quasars, galaxies with a highly energetic nucleus, is not concentrated in the region close to their central black hole but in fact extends over several thousand light-years along jets of plasma.

Mars: where mud flows like lava
Mars: where mud flows like lava
The surface of the planet Mars bears probable traces of -sedimentary volcanism-, a geological phenomenon that leads to the eruption of mud from underground. But how does a mixture of sediment and water behave in the open air on the Red Planet? Conditions there are extremely different from those on Earth - atmospheric pressure is 150 times lower and temperatures are generally negative.

New discovery: first asteroid population from outside our solar system
New discovery: first asteroid population from outside our solar system
Ka`epaoka`awela asteroid 1 surprised the world in 2018: it was the first object in the solar system that was demonstrated to be of extrasolar origin. But now those who discovered it have announced that it is not alone. Published in MNRAS on 23 April 2020, work by Fathi Namouni, a CNRS researcher in the Laboratoire Lagrange (CNRS/Observatoire de la Côte d'Azur/Université Côte d'Azur), and Helena Morais, researcher at UNESP in Brazil, proves that at least 19 other asteroids orbited another star before joining our system.

Where did the antimatter go? Neutrinos shed promising new light
Where did the antimatter go? Neutrinos shed promising new light
We live in a world of matter - because matter overtook antimatter , though they were both created in equal amounts by the Big Bang when our universe began. As featured on the cover of Nature on 16 April 2020, neutrinos and the associated antimatter particles, antineutrinos, are reported to have a high likelihood of differing behaviour that offers a promising path to explaining the asymmetry between matter and antimatter.

Mars: water could disappear faster than expected
Mars: water could disappear faster than expected
The small red planet is losing water more quickly than what theory as well as past observations would suggest. The gradual disappearance of water (H2O) occurs in the upper atmosphere of Mars: sunlight and chemistry disassociate water molecules into hydrogen and oxygen atoms that the weak gravity of Mars cannot prevent from escaping into space.

Pollution : New ammonia emission sources detected from space
Paris, December 5, 2018 Researchers from the CNRS 1 and the Université Libre de Bruxelles (ULB) have prepared the first global map of the distribution of atmospheric ammonia (NH3) by analyzing measurements taken by satellites between 2008 and 2016. The IASI interferometer developed by the CNES allowed them to catalog more than 200 ammonia sources, two-thirds of which had never been identified before.

Planck : final data from the mission lends strong support to the standard cosmological model
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 laws of star formation challenged
The laws of star formation challenged
An international team led by researchers at CNRS, Université Grenoble Alpes and the French Alternative Energies and Atomic Energy Commission (CEA) has challenged currently held ideas about star formation. The unprecedented resolution of the observations obtained using the Atacama Large Millimetre/Submillimetre Array (ALMA) enabled them to measure the quantity of high-mass star-forming cores in a remote, very active region of our Galaxy, and show that there is a higher proportion of them there than expected.
