Pérou, le secret des lignes nazcas
Les plaines désertiques du Pérou sont connues pour leurs mystérieuses lignes nazcas. Ces géoglyphes sont les vestiges d'une civilisation qui, pendant un millénaire, a laissé son empreinte dans le paysage. Cette civilisation ne possédait pas de langue écrite et, depuis leur découverte, ces lignes et des dessins représentant principalement des animaux ont toujours laissé les archéologues perplexes. Quelle est leur signification ? Et pourquoi cette tradition s'est-elle éteinte ? Des chercheurs du monde entier ont fait appel aux technologies les plus avancées pour réexaminer ces paysages et avancer de nouvelles hypothèses.
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.
