At the edge of our solar system supposedly lies an immense planet. Five to ten times the size of the Earth. Several international teams of scientists have been competing in a frantic race to detect it, in uncharted territories, far beyond Neptune. The recent discovery of several dwarf planets, with...
Several hundred million kilometers away, the space probe "Rosetta" and the small lander "Philae" orbit the sun on the comet "Churyumov-Gerasimenko", without any contact with Earth. On September 30, 2016 - two years after the launch of "Philae" - the landing of "Rosetta" on the comet marked the end...
For several decades, geoscientists have been observing that the Earth is changing rapidly due to human intervention. This action has such a great impact on the biological, geological and atmospheric processes of the Earth that some scientists speak of the dawn of a new epoch: the Age of Man or the...
It was November 12, 2014, at 5:03pm. Humanity had just accomplished a feat that will forever mark its history. Philae, the miniature laboratory integrated into the Rosetta probe, landed softly on comet 67P Chourioumov-Guérassimenko, better known as Tchouri. The culmination of a project decided...

3.62015HD
Albert Einstein's theory of general relativity has revolutionised our understanding of gravity, space and time. Initially acclaimed, then forgotten, and now rediscovered, the adventure of this hundred-year-old theory has marked the scientific history of the 20th century. From its inception, a...
Here is the “lower-risk consumption room”, the drug injection room that opened in October 2016 in a building at Lariboisière Hospital in Paris. A place that the film never quits, except for a few seconds out on a stretch of pavement, as the credits open. One or two shots are enough to...
In 1924, a garden city, called “Ungemach”, was inaugurated in Strasbourg; it was restricted to couples who bore “healthy and fertile strains”. This officially eugenicist experience was endorsed by both political and scientific authorities, and the selection system lasted until the 1980s! To...
By the time mankind is beginning to experience the first significant effects of climate change announced for decades by scientists, a major scientific campaign of clouds observation is taking place in the Caribbean, bringing together researchers from all over the world. It is no longer a question...
