A look at relevant scientific issues

Historian Patrick Boucheron revisits the most important dates in history through the prisms of memory and collective imagination.

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 intriguing trajectories, have put astronomers on the trail of this mysterious planet. Why is this enigmatic planet so difficult to detect? What would a ninth planet teach us about our corner of the universe? Could it help us unlock some of the mysteries of our solar system?

This series is based on the close relationship between Hergé’s drawings, and real people and places. Arresting and inspiring sequences of images, video and sound from exotic countries, alongside pictures from Tintin’s adventures and all kinds research material accumulated by Hergé during his lifetime, make for an unforgettable experience. If you really want to step into Hergé’s universe, what better way to do so than to follow his adventures first-hand, by foot, on horseback, by camel, by car, by boat, by train and by aeroplane!

Shows how today's Egyptian filmmakers, through fiction, documentary or participatory journalism, take action in the long and difficult process of transformation that is Revolution in their country.

Over the past few decades, significant discoveries have been made on the very site where the pyramids were built. But now, hundreds of kilometers from the pyramids themselves, we are gaining more insight into just how they were built. Two teams of Egyptologists, one based in the middle of the desert, the other located on the Red Sea coast, are currently discovering more about the Egypt of Khufu’s time, than at the foot of the pyramids. What they found help them figure out how ancient Egyptians worked. This film has been shot from within, immersed for several weeks within these 2 archaeological missions. Authentic archaeological experiments have been filmed in real time, revealing ancient techniques and methods, unlocking certain secrets of these ancient great builders.

Three years after the devastating fire at Notre-Dame Cathedral in Paris, archaeological excavations uncovered treasures that had been hidden beneath the building for centuries: In addition to numerous sculpture fragments, there were also two human-shaped lead coffins. Who are the dead in these sarcophagi? What did the sculptures represent and why are they buried under the church? By venturing into previously inaccessible areas of the Gothic sacred building, the archaeologists uncovered a forgotten part of its history. An interdisciplinary team of scientists is undertaking extensive work to uncover the secrets of Notre-Dame.
