The Secret Life of the Sun
Kate Humble and Helen Czerski reveal the inner workings of the sun and investigate why scientists think changes in the sun's behaviour may have powerful effects on our climate.
How Far Can Light Travel In 45 Minutes?
In our terrestrial view of things, the speed of light seems incredibly fast. But as soon as you view it against the vast distances of the universe, it's unfortunately very slow. This animation illustrates, in realtime, the journey of a photon of light emitted from the surface of the sun and traveling across a portion of the solar system, from a human perspective. Liberties were taken with certain things like the alignment of planets and asteroids, as well as ignoring the laws of relativity concerning what a photon actually "sees" or how time is experienced at the speed of light, but overall the size and distances of all the objects were kept as accurate as possible. It was also decided to end the animation just past Jupiter to keep the running length below an hour.

Blue Peter presenters Helen Skelton and Barney Harwood want to learn more about the solar system so they challenge scientists Helen Czerski and Jem Stansfield to find out more. They look at how to make telescopes and rockets, and use a toilet roll to measure the distances between planets.
How's it all gonna end? This experience takes us on a journey to the end of time, trillions of years into the future, to discover what the fate of our planet and our universe may ultimately be. We start in 2019 and travel exponentially through time, witnessing the future of Earth, the death of the sun, the end of all stars, proton decay, zombie galaxies, possible future civilizations, exploding black holes, the effects of dark energy, alternate universes, the final fate of the cosmos - to name a few.
The Academy Award® nominee Cosmic Voyage combines live action with state-of-the-art computer-generated imagery to pinpoint where humans fit in our ever-expanding universe. Highlighting this journey is a "cosmic zoom" based on the powers of 10, extending from the Earth to the largest observable structures in the universe, and then back to the subnuclear realm.
Just outside Paris, France, inside a high-tech vault, requiring three independently controlled keys, rests a small metallic cylinder about the diameter of a golf ball. Encased within three vacuum-sealed bell jars it may not look like much, but it is one of the most important objects on the planet. It affects nearly every aspect of our lives from the moment we are born, to the food we eat, the cars we drive, and even the medicines we take. The Last Artifact follows the high-stakes race to redefine the weight of the world reveals the untold story of one of the most important objects on the planet. The kilogram, the base unit of mass in the International System of Units, helped send humans to the moon and satellites into space. This small hunk of metal is the object against which all others are measured. Yet over time, its mass mysteriously eroded by the weight of an eyelash. A change that, unbeknownst to most, unleashed a crisis with potentially dire consequences.
Richard Feynman was a scientific genius with - in his words - a "limited intelligence". This dichotomy is just one of the characteristics that made him a fascinating subject. The Pleasure of Finding Things Out exposes us to many more of these intriguing attributes by featuring an extensive conversation with the acclaimed Nobel Prize winner. During the course of the interview, which was conducted in 1981, Feynman uses the undeniable power of the personal to convey otherwise challenging scientific theories. His colorful and lucid stories make abstract concepts tangible, and his warm presence is sure to inspire interest and awe from even the most reluctant student of science. His insights are profound, but his delivery is anything but dry and ostentatious.
This shows physicist Stephen Hawking's life as he deals with the ALS that renders him immobile and unable to speak without the use of a computer. Hawking's friends, family, classmates, and peers are interviewed not only about his theories but the man himself.
A short documentary about an engineer in a Chilean observatory.
A short documentary interviewing a renown astronomer and astrophysicist.
The show tells a thrilling story of the most remarkable space mission in human history.
Physicist Dr Helen Czerski takes us on a journey into the science of bubbles - not just fun toys, but also powerful tools that push back the boundaries of science.
This documentary examines theories behind the creation of gamma ray bursts, destructive explosions in space that can wipe out entire star systems.
Three billion miles away a grand-piano-sized spacecraft is speeding through the outer solar system at nearly 1,000 miles per minute. After nearly a decade in space, the New Horizons space probe will have just 86 seconds to complete its primary mission: Discover the planet Pluto. This time-sensitive special will showcase the first quality pictures of Pluto that the probe will capture.
Man has always sought to seek further afield. After the seafaring explorers of the 16th century, 21st century cosmologists today navigate more celestial oceans, with each mission providing an ever-broader and more impressive cartography of our surroundings. At the avant garde of modern technology, these strange travellers are actually immobile, and their vessels are powerful and spectacular telescopes, on the Earth or in space, constantly widening the limits of our knowledge and giving form to our dreams of infinity. From Hawaii to Australia, via South Africa and China, we set out on an incredible scientific and human adventure to visit the planet's greatest cosmic exploration centres to discover the new challenges involved in understanding the universe. A journey on Earth and in the heavens that will take your breath away!
A group of renowned cosmologists and astrophysicist are in search of a realistic picture of the universe. Their research and observational discoveries point in a direction diametrically opposed to the predominant Bog Bang theory - this leads to a series of sociological situations that verge on the extreme dogma controls wielded against Copernicus and Galileo in the past; only now against our protagonists of the 21st century. This is a controversial science documentary touching on the nerve of everything astronomers and cosmologist claim they know about the universe today. - Written by Meyers, Randall
The captivating tales of the people and events behind one of humanity's greatest achievements in exploration: NASA's Voyager mission.
Although the mountain volcano Mauna Kea last erupted around 4,000 years ago, it is still hot today, the center of a burning controversy over whether its summit should be used for astronomical observatories or preserved as a cultural landscape sacred to the Hawaiian people. For five years the documentary production team Nā Maka o ka 'Āina ("the eyes of the land") captured on video the seasonal moods of Mauna Kea's unique 14,000-foot summit, the richly varied ecosystems that extend from sea level to alpine zone, the legends and stories that reveal the mountain's geologic and cultural history, and the political turbulence surrounding the efforts to protect the most significant temple in the islands: the mountain itself.
A world leading team of ultra-low temperature physicists at Lancaster University decided to place a LEGO figure and four LEGO blocks inside their record-breaking dilution refrigerator. This machine - specially made at the University - is the most effective refrigerator in the world, capable of reaching 1.6 millidegrees above absolute zero (minus 273.15 Centigrade), which is about 200,000 times colder than room temperature and 2,000 times colder than deep space.
Canada is leading the way when it comes to dark sky preservation and the fight against light pollution. See how dark sky preserves in Wood Buffalo, Jasper and Elk Island National Parks educate the public about the importance of protecting the night sky for the health of humans and wildlife. Then visit star parties in British Columbia and Alberta where amateur astronomers and astrophotographers watch and celebrate the night sky.
