You find fungi in Antarctica and in nuclear reactors. They live inside your lungs and your skin is covered with them. Fungi are the most under appreciated and unexplained organisms, yet they could cure you from smallpox and turn cardboard boxes into forests. They could even transform Mars into Eden. There are vastly more fungi species than plants and each and every one of them plays a crucial role in life’s support systems. Join us on a journey into the mysterious world of Fungi to witness their beauty, unravel their mysteries and discover how this secret kingdom is essential to life on Earth, and may in fact hold the key to our future.

This episode is centered around how science, in particular the work of Clair Patterson (voiced in animated sequences by Richard Gere[33]) in the middle of the 20th century, has been able to determine the age of the Earth. Tyson first describes how the Earth was formed from the coalescence of matter some millions of years after the formation of the Sun, and while scientists can examine the formations in rock stratum to date some geological events, these can only trace back millions of years. Instead, scientists have used the debris from meteor impacts, such as the Meteor Crater in Arizona, knowing that the material from such meteors coming from the asteroid belt would have been made at the same time as the Earth. Patterson also examined the levels of lead in the common environment and in deeper parts of the oceans and Antarctic ice, showing that lead had only been brought to the surface in recent times. He would discover that the higher levels of lead were from the use of tetraethyllead in leaded gasoline resulting in government-mandated restrictions on the use of lead.

This is one of the most ambitious animated programmes ever attempted for broadcast TV, recreating every detail of these extraordinary animals in an entirely digital production that stretches the boundaries of broadcast 3D with a scale and ambition normally reserved for Hollywood feature films. Planet Dinosaur 3D is a thrilling and immersive journey into a lost world. Pulling together cutting edge research from around the world this programme uses the latest, stunning fossil evidence to chart the rise and fall of the 'Ultimate Killers'; from the iconic Spinosaurus, the largest predator ever to walk the Earth, to Microraptor and the feathered, flying dinosaurs from China. At last, thanks to the advances in technology, and for the first time ever, these monsters can be experienced in all their full, magnificent wonder.

For thousands of years, humans have believed that there were once flying monsters. But did they really exist beyond our nightmares? 220 million years ago dinosaurs were beginning their domination of Earth. But another group of reptiles was about to make an extraordinary leap: pterosaurs were taking control of the skies. The story of how and why these mysterious creatures took to the air is more fantastical than any fiction. In Flying Monsters 3D, David Attenborough the worlds leading naturalist, sets out to uncover the truth about the enigmatic pterosaurs, whose wingspans of up to 40 feet were equal to that of a modern day jet plane. Attenborough works with scientists to understand the incredible story of the evolution of the pterosaurs, a story that unfolds in such stunning locations as New Mexico, the Jurassic Coast of Lyme Regis in Britain, an ancient pterosaur landing site in Southern France and a fossil pit in Germany where near perfect pterosaur specimens have been found. The central question and one of the greatest mysteries in palaeontology is: how and why did pterosaurs fly? How did lizards the size of giraffes defy gravity and soar through prehistoric skies? Driven by the information he finds as he attempts to answer these questions, Attenborough starts to unravel one of sciences more enduring mysteries, discovering that the marvel of pterosaur flight has evolutionary echoes that resonate even today. Flying Monsters 3D is a groundbreaking film that uses cutting-edge 3D technology and CGI to bring the story of giant flying monsters and their prehistoric world to life. Audiences of all ages will be in awe as they enter the world and experience, as never before, REAL Flying Monsters in 3D.

The constellation of the Pleiades provides a vehicle for us to explore a series of paradoxes and epochal discoveries for humanity. The untold story of the modern "sisters of the sun," the early 20th century female astronomers, led by two deaf women, at Harvard who catalogued the stars. It's also the story of the young British woman who joined forces with them, her defiance of the world's leading expert, and how she taught the world what the stars are really made of.

The episode begins with Tyson describing how pattern recognition manifested in early civilization as using astronomy and astrology to predict the passing of the seasons, including how the passage of a comet was often taken as an omen. Tyson continues to explain that the origin of comets only became known in the 20th century due to the work of Jan Oort and his hypothesis of the Oort cloud. Tyson then continues to relate the collaboration between Edmond Halley and Isaac Newton in the last part of the 17th century in Cambridge. The collaboration would result in the publication of Philosophiæ Naturalis Principia Mathematica, the first major work to describe the laws of physics in mathematical terms, despite objections and claims of plagiarism from Robert Hooke and financial difficulties of the Royal Society of London. Tyson explains how this work challenged the prevailing notion that God had planned out the heavens, but would end up influencing many factors of modern life, including space flight. Tyson further describes Halley's contributions including determining Earth's distance to the sun, the motion of stars and predicting the orbit of then-unnamed Halley's Comet using Newton's laws. Tyson contrasts these scientific approaches to understanding the galaxy compared to what earlier civilizations had done, and considers this advancement as mankind's first steps into exploring the universe. The episode ends with an animation of the Milky Way and Andromeda galaxies' merging based on the principles of Newton's laws.
