Pollution : New ammonia emission sources detected from 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.

A new method for weighing super-massive black holes
A new method for weighing super-massive black holes
Paris, 29 November 2018 Scientists have revealed, for the first time outside our Galaxy, the properties of rapidly moving gas clouds in the immediate vicinity of a super-massive black hole, enabling the mass of the black hole to be measured with unprecedented accuracy.

Parker Solar Probe : French research takes off for the Sun
Parker Solar Probe : French research takes off for the Sun
Parker Solar Probe will soon become the spacecraft to travel the closest to the Sun, by positioning itself a little over 6 million kilometers from our star's surface. During its journey within the solar corona, the NASA probe will notably have an on-board instrument developed by researchers from the CNRS, université d'Orléans, and the CNES.

GRAVITY confirms predictions of general relativity near the Galactic Centre Massive Black Hole
GRAVITY confirms predictions of general relativity near the Galactic Centre Massive Black Hole
Observations made with the Very Large Telescope (VLT) of the European Southern Observatory (ESO) have, for the first time, detected the effects of general relativity predicted by Einstein, in the movement of a star passing into the intense gravitational field of Sagittarius A * , a massive black hole at the centre of the Milky Way.

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

First light for SPIRou, exoplanet hunter
First light for SPIRou, exoplanet hunter
SPIRou, the new planet-hunting spectropolarimeter developed for the Canada-France-Hawaii Telescope (CFHT), has successfully recorded its first starlight. Ten years after it was first designed and following four intensive months of installation at CFHT, this international instrument in which France has played a leading role is on the point of initiating its scientific operations, namely the detection of exoplanets around nearby red dwarf stars and the study of newborn stars and planets.

Discovery of the first body in the Solar System with an extrasolar origin
Discovery of the first body in the Solar System with an extrasolar origin
Asteroid 2015 BZ509 is the very first object in the Solar System shown to have an extrasolar origin. This remarkable discovery was made by CNRS researcher Fathi Namouni and her Brazilian colleague Helena Morais, and is published on 21 May 2018 in MNRAS . Could some bodies in our Solar System come from the vicinity of other stars' Astronomers are in disagreement about comets, with some arguing that certain comets may have formed around other stars before being captured by the Sun, although they have never been able to prove it.

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.

The largest catalog ever published of very high energy gamma ray sources in the Galaxy
The largest catalog ever published of very high energy gamma ray sources in the Galaxy
The HESS international collaboration, to which CNRS and CEA contribute, has published the results of fifteen years of gamma ray observations of the Milky Way. Its telescopes installed in Namibia have studied populations of pulsar wind nebulae and supernova remnants, as well as microquasars, never before detected in gamma rays.

Comet Chury formed by a catastrophic collision
Comet Chury formed by a catastrophic collision
Comets made up of two lobes, such as Chury, visited by the Rosetta spacecraft, are produced when the debris resulting from a destructive collision between two comets clumps together again.

A French nano satellite to unveil the mysteries of Beta Pictoris
PicSat will be launched into Earth orbit on 12 January 2018 to study the star Beta Pictoris, its exoplanet and its famous debris disk, thanks to a small telescope 5 cm in diameter.

New early signals to quantify the magnitude of strong earthquakes
After an earthquake, there is a disturbance in the field of gravity almost instantaneously. This could be recorded before the seismic waves that seismologists usually analyze. In a study published in Science on December 1, 2017, a team formed of researchers from CNRS, IPGP, the Université Paris Diderot 1 and Caltech has managed to observe these weak signals related to gravity and to understand where they come from.

Gravitational waves shed first light on mergers of neutron stars
This is a major breakthrough in more than one respect. The scientists of the LIGO-Virgo Collaboration (which includes the CNRS) have for the first time observed the gravitational waves emitted by the merger of two neutron stars, rather than of two black holes as in previous cases. In another first, the light emitted from the source of gravitational waves was observed in the following hours, days and weeks, by 70 other groundand space-based observatories.

Highest-energy cosmic rays have extragalactic origin
Highest-energy cosmic rays have extragalactic origin
A 50-year-old debate has at last been settled: the highest-energy cosmic rays do not originate in our own Galaxy but in galaxies located tens or even hundreds of millions of light years away.

Does the organic material of comets predate our Solar System ?
Does the organic material of comets predate our Solar System ?
The Rosetta space probe discovered a large amount of organic material in the nucleus of comet “Chury.” In an article published by MNRAS on August 31, 2017, two French researchers advance the theory that this matter has its origin in interstellar space and predates the birth of the Solar System. The ESA's Rosetta mission, which ended in September 2016, found that organic matter made up 40% (by mass) of the nucleus of comet 67P Churyumov-Gerasimenko, a.k.a.

The Sun's core makes a complete rotation in one week
The Sun’s core makes a complete rotation in one week
The rotation rate of the Sun's core has been accurately measured for the first time. The Sun, which has been remarkably stable for the past 4.6 billion years, is held together by the almost perfect equilibrium between the force of gravity, which tends to cause it to collapse, and the pressure of the thermonuclear reactions in its core.

First discovery of an exoplanet by SPHERE
First discovery of an exoplanet by SPHERE
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.
