In just half a century, the human population has doubled to 7.4 billion, and during that time, astronaut and satellite photos have been capturing the startling changes on our planet. See how humans have made their mark reshaping the planet in our quest for new sources of food, power, and shelter.
From glimmering new megacities like Shenzhen, China to areas affected by climate change like Mt. Kilimanjaro and Florida, witness Earth's changing look--the spectacular and the shocking--from 250 miles up.

Ferdinand Magellan and Juan Sebastian Elcano set sail to gain control of the global spice trade, but end up becoming the first expedition to circumnavigate the earth. The yearslong voyage—along with the suffering, the violence and the loss of life and property—were all in pursuit of a shorter route to the so-called Spice Islands (now the Maluku Islands) and their much-coveted aromatics.
The film puts in perspective the 16th century—the Age of Exploration, the Age of Discovery and the Age, problematically, of Colonialism. It also was an age of heroes. As the documentary insists, the journeys undertaken by the men whose names we learned in grade school and whose exploits straddled the 1400s and 1500s—including Ponce de Leon, Vasco da Gama, Lope de Aguirre and even Columbus—were about money, sometimes trade, sometimes plunder. But just as advances in medicine have often been propelled by war, knowledge about the world has been a byproduct of profit-seeking. Likewise, heroism.

In August 1977, the Big Ear Radio-telescope in Ohio received a strange signal from the Sagittarius constellation while searching for intelligent extra-terrestrial life. It had a duration of 72 seconds and an intensity 30 times higher than usual. Named the Wow signal, it is still being considered as one of the best examples of having being sent by intelligent extraterrestrial life. But, nothing has revolutionised the search of extra-terrestrial intelligent life as much as the recent discovery by the Kepler Satellite, of thousands of Earth-like planets where life could be possible. Join the debate with this stunning documentary, as we ask Is Anybody Out There?

The world’s first flying car might be on the market sooner than we think, and as a new, cutting-edge invention goes through a series of gruelling tests, behind-the-scenes access reveals the secrets of this sci-fi innovation. With the ability to carry up to 250 kg (551 lb) of payload at speeds up to 80 km/h (50 mph), the 12-rotor Seraph is developed by the Bristol-based company aptly named Vertical Aerospace, and is the Britain's leading electric VTOL (vertical take-off and landing) air taxi candidate.

The film explores the revolutionary gene-editing tech now giving humankind the freedom to redraw the blueprint of biological life itself. We investigate not only the tremendous potential the technology holds, whether in the fight to eliminate diseases or in transforming agriculture to adapt to unprecedented climate extremes, but also probe the inherent risks involved and the potential for widespread abuse, dangers that could take our future down a very dark, dystopian path.

This scientific detective tale tells the story of a remarkable group of pioneers who wanted to reach the ultimate extreme: absolute zero, a place so cold that the physical world as we know it doesn't exist, electricity flows without resistance, fluids defy gravity and the speed of light can be reduced to 38 miles per hour. Absolute zero became the Holy Grail of temperature physicists and is considered the gateway to many new technologies, such as nano-construction, neurological networks and quantum computing. The possibilities, it seems, are limitless. The first episode Chronicles the major discoveries leading towards the mastery of cold, beginning with King James I's court magician, Cornelius Drebbel, who managed to air condition the largest interior space in the British Isles in 1620. Other stories will include the first "natural philosopher," Robert Boyle, a founder of the Royal Society in Great Britain; the Grand Duke Ferdinand II de Medici's involvement in the creation of the first thermometer; the establishment of the laws of thermodynamics by three young scientists, Sadi Carnot, James Joule and William Thomson; and Michael Faraday's critical achievement in liquefying several other gases which set the stage for the commercial application of cold to refrigeration and air conditioning.
