In Breathing Life Into Earth, geologist Iain Stewart explains how oxygen left the ocean and filled the atmosphere, creating a huge turning point in the story of life on Earth. This oxygen helped form the ozone layer, which acts like a protective shield, blocking harmful radiation from the Sun and allowing life to thrive. Without oxygen, Earth wouldn’t have been able to support all the amazing life forms we know. 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.
In Earth's Epic Comebacks, geologist Iain Stewart explores how Earth's history of disasters has shaped life and sparked evolution. From dinosaurs thriving after a mass extinction to bacteria surviving an ice age, Earth has always found a balance between stability and chaos. Now, humans are changing the climate and marking a new era called the Anthropocene. The question is: can we protect the planet that makes life so incredible? 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.
In Early Elements: Mars and Earth, Professor Brian Cox explains what Mars and Earth looked like when they were formed. Learn which was the original “blue 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.
In Energy From the Earth: The Conditions for Life, Professor Brian Cox brings us to Taal Lake in the Philippines. Watch energy bubble up from below the Earth’s surface and learn how this energy creates a natural battery that can be used to power a motor. Where else on Earth can we find these high energy conditions? This video is excerpted from BBC’s The Planets, a series that explores the dramatic lives of the eight planets in our Solar System.
In Two Planets, Two Paths: Inside Earth and Mars, Professor Brian Cox explains what happened 4.6 billion years ago when Mars and Earth formed. The formation set these two planets, which were made of similar material, on very different paths. Learn how the magnetic field around Earth provides protection and how Mars’s magnetic field died out. This video is excerpted from BBC’s Brian Cox’s Adventures in Space and Time, a series that seeks to explain our place in the Universe. Professor Brian Cox looks back on decades of discovery and toward the next frontier in space, pondering the question: What’s next?
In How Rare Is Our Planet: Earth’s Uniqueness in the Universe, Dr. Lynn Rothschild explains the delicate balance that makes Earth unique. She focuses on the habitable zone — the perfect distance from the Sun that allows liquid water to exist allowing life to thrive. This exact positioning results in a tiny wobble in the star, which makes it extremely challenging to find another planet with conditions similar to Earth’s.
In Once a Red Planet, Always a Red Planet? The Birth of Mars, Professor Brian Cox explains how when Mars and Earth were born, they had similar atmospheres and were made of similar material, but the two planets took dramatically different paths. Learn how different Mars is from Earth, and how much Mars has changed in 4.6 billion years. This video is excerpted from BBC’s The Planets, a series that explores the dramatic lives of the eight planets in our Solar System.
In The Moon and the Tides, Ranger Hamza and the Ramblers observe that the tide has gone out. Join the Ramblers as they learn how the Moon impacts the tides all around the Earth. This video is excerpted from BBC's Ranger Hamza’s Eco Quest, a nature exploration show in which Ranger Hamza and the Ramblers go on quests to discover nature’s wonders and the important role they play in our environment.
In Tides: How Low Can You Go?, Ranger Hamza and the Ramblers explore a promenade by the ocean. They know the tide comes in and out, but is it high tide or low tide? This video is excerpted from BBC's Ranger Hamza’s Eco Quest, a nature exploration show in which Ranger Hamza and the Ramblers go on quests to discover nature’s wonders and the important role they play in our environment.
In Don't Miss the Solar Eclipse!, the Go Jetters watch a solar eclipse. Ubercorn explains what’s happening during an eclipse and why we should protect our eyes while watching one. This video is excerpted from BBC’s Go Jetters, a series that follows the adventures of four international heroes as they travel the globe visiting landmarks and solving environmental problems with Ubercorn, a disco-dancing unicorn.
