Terres extrêmes : Chili
Depuis le désert de l’Atacama, le plus aride au monde, jusqu’à la Patagonie battue par des pluies constantes, Heidi arpente les zones les plus hostiles du Chili. Après avoir parcouru le désert de l’Atacama pour appréhender son extrême aridité, Heidi rencontre des scientifiques qui ont su tirer parti de ce lieu unique. Sur les hauts plateaux à 5200 mètres d’altitude, elle découvre ALMA, le plus grand radiotélescope au monde. Des découvertes fascinantes sur les origines de l’univers ont pu être observées ici. Heidi se rend ensuite dans une base expérimentale, alimentée en eau par d’étonnants « attrapes-nuages ». L’idée astucieuse étant de récupérer de l’eau à partir de l’humidité contenue dans les nuages. 4000 km plus au sud, notre scientifique rejoint une équipe de glaciologues britanniques. Dans une vallée reculée de Patagonie, ils explorent sur le terrain le rôle joué par les glaciers dans l’écosystème de notre planète.
Season 11 of Science grand format premieres in 12 days, on September 10, 2026, and the timing could not be better for viewers who like their prime-time television to feel both spectacular and genuinely informative. The long-running French documentary collection returns with a new run dedicated to major discoveries, scientific mysteries and historical investigations, opening with an ambitious space odyssey before turning to one of the most mythologized episodes in European history: Julius Caesar’s victory over the Gauls and Vercingetorix. If you follow factual series on BetaSeries, this is exactly the kind of premiere you will want to track early, because Season 11 already looks designed for viewers who enjoy documentaries that combine accessible storytelling with cutting-edge research.
For lapsed viewers, here is all you really need to remember before the new season begins. Science grand format is not a traditional serialized show with characters, cliffhangers or a single ongoing plot. Across its previous ten seasons and hundreds of episodes, the series has built its identity around standalone documentary events: French productions and international co-productions that explore archaeology, space, nature, ancient civilizations, technology and the big scientific questions shaping how we understand the world. It sits comfortably alongside programs such as Découverte, Le Monde de Jamy, Zeste de Science, The Complete Cosmos, Exploring Space or Ancient X-Files, but with a prime-time scale and a taste for immersive investigations.
That format is a real advantage heading into Season 11. You do not need to rewatch 349 episodes to be ready for the premiere. Instead, you can jump straight into the new season and let each episode function as its own expedition. What carries over from past seasons is the series’ core promise: experts, researchers, archaeologists, historians and scientists guide viewers through discoveries in progress, often challenging received ideas. The pleasure of Science grand format is not simply learning a fact; it is watching knowledge being tested, reconstructed and sometimes overturned.
