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.

Gravitational waves detected for first time from two stars colliding
This discovery of neutron stars colliding is just the beginning. We want to one day look back to the beginning of time - just after the Big Bang, which we can't do with light. Scientists from ANU and around the world have detected for the first time ripples in space and time, known as gravitational waves, from the collision of two very dense stars, called neutron stars, about 130 million light years away.

First detection of gravitational waves from colliding neutron stars
Scientists have for the first time directly observed gravitational waves, in addition to light, emitted from the spectacular collision of two neutron stars. The detection marks the first time that a cosmic event has been viewed in both gravitational waves and light. The gravitational wave signal, named GW170817, was detected at 1:41pm UK time on 17 August by two identical detectors in Washington and Louisiana and a third detector in Pisa, Italy.

First detection of gravitational waves and light produced by colliding neutron stars
First detection of gravitational waves and light produced by colliding neutron stars
In a galaxy far away, two dead stars begin a final spiral into a massive collision. The resulting explosion unleashes a huge burst of energy, sending ripples across the very fabric of space. In the nuclear cauldron of the collision, atoms are ripped apart to form entirely new elements and scattered outward across the Universe. What I am most excited about, personally, is a completely new way of measuring distances across the universe.

Latest gravitational-wave detection opens new era for astronomy
The discovery of a gravitational wave caused by the merger of two neutron stars, reported today by a collaboration of scientists from around the world, opens a new era in astronomy. It marks the first time that scientists have been able to observe a cosmic event with both light waves - the basis of traditional astronomy - and gravitational waves, the ripples in space-time predicted a century ago by Albert Einstein's general theory of relativity.

Intense storms batter Saturn’s largest moon, UCLA scientists report
Titan, the largest of Saturn's more than 60 moons, has surprisingly intense rainstorms, according to research by a team of UCLA planetary scientists and geologists. Although the storms are relatively rare — they occur less than once per Titan year, which is 29 and a half Earth years — they occur much more frequently than the scientists expected.

New crew and new research in Antarctica
New crew and new research in Antarctica
The Concordia research station in Antarctica is a place of extremes: for nine months no supplies can be delivered, the nearest living beings are 600 km away at the Russian Vostok station, and the Sun does not rise above the horizon for four months in the winter. One thing is for sure: it is cold, dropping below -80C, and the high altitude offers reduced oxygen in the air.

New research uncovers 90 million years of history of Martian volcano
Analysis of Martian meteorites has uncovered 90 million years' worth of new information about one of the red planet's volcanoes - and helped pinpoint which volcano the meteorites came from. Geologists based in the UK and the USA have used advanced mass spectrometry techniques to learn more about the origins of six meteorites known as ‘nakhlites' - pieces of Martian terrain which were blasted from the face of the red planet by an impact event 11 million years ago, then drifted through space before landing on Earth.

Traces of Methyl Chloride around Infant Stars and Nearby Comet
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have detected the faint molecular fingerprint of methyl chloride - a chemical commonly produced by industrial and biological processes here on Earth - around an infant star system known as IRAS 16293-2422. Traces of this organic compound were also discovered in the thin atmosphere of comet 67P/Churyumov-Gerasimenko (67P/C-G) by the Rosetta space probe.
