In A Journey to the Edges of the Solar System, learn all about the Voyager probes launched in 1977 that returned with exciting new images of Saturn and its rings. Data revealed that its atmosphere is made up of helium and hydrogen, a critical piece in understanding the planet’s evolution. This video is excerpted from BBC’s The Planets, a documentary series hosted by Professor Brian Cox that explores the dramatic lives, formation, and unique features of the eight planets in our Solar System through stunning visuals and scientific insights.
In The Death of Stars, narrator Kate Yule explores how stars reach the end of their lives and can no longer fight against their own gravity. Some stars expand, whereas giant stars contract to form black holes, invisible to telescopes. Learn how Jocelyn Bell Burnell built a new telescope which detected pulsars, which emit no visible light, but send out radio waves. 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.
In Pizza and the pH of Cheese presenter Cherry Healey visits a lab at the University of Reading to learn why mozzarella cheese is the most popular cheese when it comes to pizza. Could any other cheese have the right properties to be pizza-worthy? Learn how it all depends on pH, water concentration, and stretchability. This video is excerpted from BBC’s Inside the Factory, a series that takes viewers behind the scenes in the factories that make our favorite products.
In How a Poisonous Lake Reveals an Ancient Catastrophe, geologist Iain Stewart highlights scientists exploring a toxic mystery behind the Permian mass extinction. While the surface teems with life, the lake’s bottom holds deadly hydrogen sulfide, turning the water pink with millions of purple bacteria. These bacteria are key to understanding how, 250 million years ago, this toxic gas escaped into the air, devastating life on Earth. This video is excerpted from BBC’s Earth: The Power of the Planet, a documentary series in which Dr. Iain Stewart discovers how Earth's forces can shape nature, species, and even the climate.
The article "Understanding Water: The Key to Life on Earth" from BBC's Science Focus explains how water’s physical properties, like hydrogen bonding, allow it to support life on Earth. It highlights the importance of water in living organisms, the water cycle, and the discovery of water in space.
In Inside Planetary Storms, Professor Brian Cox explores the extreme weather conditions on Jupiter, a planet with an incredibly thick atmosphere that fuels its intense storms. Despite being far from the Sun, Jupiter’s storms are powered by immense surface pressure. This atmospheric pressure causes hydrogen gas to transform into a liquid, releasing vast amounts of energy and creating some of the most powerful storms in the Solar System. This video is excerpted from BBC’s Wonders of the Solar System, a spellbinding documentary series that explores the most extreme locations on Earth to explain how the laws of physics carved natural wonders across the Solar System.
