Exoplanets, the search for new worlds?

In October 1995, a team of astrophysicists led by Michel Mayor and Didier Queloz at the Haute-Provence Observatory in southeastern France became the first to formally discover an exoplanet, a hot Jupiter dubbed 51 Pegasi b. Since then, more than 3,000 exoplanets have been officially identified, while researchers still have to confirm the discovery of a further 2,400.

Solar Energy

What is the current state of solar energy in France and around the world? What are the technologies that will drive its development? What are the obstacles involved? What are the latest scientific breakthroughs in this field? The 20th report in the CNRS/sagascience collection focuses on solar energy and its prospects for the future, in particular at a time when the energy transition is an important topic of debate in France. Conceived for the general public, this multimedia presentation sheds light on the key challenges in the use of solar power, which has the potential to meet most of our energy needs if solutions can be developed for converting sunlight efficiently and at low cost.

Nuclear Energy

Coinciding with France's ongoing debate on energy transition, the CNRS/sagascience collection releases a report on the current state of nuclear energy.
This multimedia report is structured around four main themes: discovery of natural radioactivity; nuclear energy production; social aspects of nuclear energy in the wake of Fukushima; future energy production, fuel reprocessing and waste storage technologies.

Image Climate

The Earth's climate

Why is it that life on Earth as we know it would not have been possible without the natural "greenhouse effect"? Why do we have seasons? What exactly is solar radiation, the driving force behind the climate? How do atmospheric and oceanic circulation patterns determine terrestrial climates? How do the planet's major biomes depend on the climate?

All these questions are answered in a multimedia animation enlivened with computer graphics, interactive maps, films and photos.

Greening the City

Greening the City takes an inside look at urban areas and their natural spaces, exploring the little-known but existing links among their various inhabitants: people, animals and plants. How does biodiversity benefit city dwellers? What is an eco-friendly neighborhood? What role should nature play in the city? Will the city of tomorrow be green?

This multimedia animation was created to accompany two major events in 2010: the International Year of Biodiversity and Expo 2010 in Shanghai, China, whose theme was "Better City, Better Life."

Darwin, a naturalist's voyage around the World

Set sail aboard the H.M.S. Beagle and relive Charles Darwin's adventure around the world. Discover, in 14 stages, the epic journey that enabled the famous naturalist (1809-1882) to formulate his theory of evolution by means of natural selection.

This animation site was created to mark the Year of Darwin (2009), which celebrated the bicentennial of his birth as well as the 150th anniversary of the publication of his seminal work on The Origin of Species.
