Mercury: A Planet Exposed

In Mercury: A Planet Exposed, narrator Professor Brian Cox highlights the brutal environment of the smallest planet in our Solar System. Its small size meant Mercury didn’t have enough gravity to hang on to its atmosphere. Without the protection of even that thin line of gas, temperatures fluctuate from 842°F (450°C) during the day to -290°F (-180C) degrees at night on the rocky planet. This video is excerpted from BBC’s The Planets, a series that explores the dramatic lives of the eight planets in our Solar System.

Einstein’s Theory of General Relativity: An Elegant Equation

In Einstein’s Theory of General Relativity: An Elegant Equation, narrator Kate Yule explores Einstein’s realization that a key feature of space-time is that it could bend and flex. The Sun changes space-time, which Einstein suggests is the true nature of gravity. Learn how Einstein created an equation to express the curvature of space and time. This video is excerpted from BBC’s Einstein & Hawking: Masters of Our Universe, a mind-bending documentary that tells the story of how the two most famous scientists of the 20th Century transformed our understanding of the Universe and changed the world.

The Gravity-Defying Design of the Caracal Cat
In The Gravity-Defying Design of the Caracal Cat, narrator Suranne Jones looks at the perfect design of the caracal, a wild cat, that allows it to leap upwards, defying gravity and catching birds in flight. Even more amazing is how the cat uses its flexible spine to twist its body two different ways so that it can push off itself and land on its feet no matter what. This video is excerpted from BBC’s Life in the Air, a documentary about animals that take to the sky.
