There is a region of space that is dangerous for reasons we don't yet understand completely. We see an increased flux of energetic particles in this area and higher-than-usual levels of radiation. It's called the South Atlantic Anomaly. Some scientists now think the long-term effects of this danger zone may be far wider reaching than anyone ever expected, and it may even have implications for the future of humanity in space and on Earth.

The season 8 of Space Deepest Secrets shares the stories of deep-space explorers who are risking their careers, and even their lives, to lead humanity to worlds yet to be seen.
In the first episode, astronomers are laying the groundwork to locate a new planet for the human race to inhabit, and the more alien worlds they discover and encounter, the more they unmask the mysterious and truly destructive nature of the cosmos.

In the past few decades, scientists have learned that the basis of everything they thought they knew about bird brains—that they were largely comprised of the most primitive and instinctual of brain structures—was wrong. Fully 75 percent of the brains of parrots and thousands of other species of birds is actually made up of a sophisticated information processing system that works much the same way as the locus of human higher-mindedness, the cerebral cortex.
The film shows scientists putting birds to the test. Can they solve problems? Can they cooperate? Do they feel emotion? New research demonstrates just how clever they can be.

Using cutting-edge research, a dedicated team of archaeologists has compiled the evidence to fill in a 400-year gap in man's knowledge of the bluestones of Stonehenge. By combining innovative 3D scanning techniques, traditional field archaeology and novel laboratory analysis, the team has discovered where the stones were quarried and where they first stood.
Professor Alice Roberts shows how the team made its discoveries and joins Professor Mike Parker Pearson to piece together the final parts of the puzzle, solving one of the toughest challenges ever faced by archaeologists.

Ma Anand Sheela emerges as a provocative spokeswoman. The Rajneesh control Antelope city council and they establish a police force in the city. Bhagwan tells Sheela it is time to control Wasco County. As Election Day approaches, the Rajneeshees recruit thousands of homeless people to fortify their ranks.

Dinosaurs ruled the earth for 150 million years, then suddenly they were gone. Their disappearance is one of the planet’s greatest mysteries – unimaginable, until now. The film proposes a minute-by-minute chronology of the Chicxulub impact and its effect on the dinosaurs and other animals around the world. A blow-by-blow account of the cataclysm that ended the reign of the dinosaurs, and forever changed the course of life on Earth.
