0.0Science Breakthroughs: Homo Naledi Discovered in 2013, new and puzzling finding of small-skulled fossils of Homo Naledi has scientists trying to understand whether Homo Sapiens lived at the same time as Homo Naledi, and how Homo Naledi communities may have lived.
6.7This documentary delves into the mysteries surrounding the Neanderthals and what their fossil record tells us about their lives and disappearance.
7.2At the edge of our solar system supposedly lies an immense planet. Five to ten times the size of the Earth. Several international teams of scientists have been competing in a frantic race to detect it, in uncharted territories, far beyond Neptune. The recent discovery of several dwarf planets, with intriguing trajectories, have put astronomers on the trail of this mysterious planet. Why is this enigmatic planet so difficult to detect? What would a ninth planet teach us about our corner of the universe? Could it help us unlock some of the mysteries of our solar system?
7.2New planets are now being discovered outside our solar system on a regular basis, and these strange new worlds are forcing scientists to rewrite the history of our own solar system. Far from a simple story of stable orbits, the creation of our solar system is a tale of hellfire, chaos and planetary pinball. It's a miracle our Earth is here at all.
0.0Computer animation and footage from NASA space missions explain how our solar system evolved and the place Earth has within the system.
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.
6.5Nowadays we associate Johannes Kepler with his famous laws of planetary motion. But the history of his discoveries is a drama of Shakespearian proportions - full of intrigue, passion, depravity and corruption.
7.5Neandertal man disappeared abruptly 30,000 years ago. Who was that "other" man and what is the most plausible hypothesis leading to his extinction? An investigation using all current knowledge available tries to answer these questions.
0.0NOVA's groundbreaking investigation explores how new discoveries are transforming views of our earliest ancestors. Becoming Human explores the origins of us -where modern humans and our capacities for art, invention, and survival came from, and how our social history led to 3-5% of our genetic heritage being Neanderthal. Featuring interviews with world-renowned scientists, footage shot in the trenches as fossils were unearthed, and stunning computer-generated animation, Becoming Human brings early hominids to life, examining how they lived and how we became the creative and adaptable modern humans of today. In gripping forensic detail, we meet: Selam, the amazingly complete remains of a 3 million year-old child, packed with clues to why we split from the apes, came down from the trees, and started walking upright; Turkana Boy -a tantalizing fossil of Homo erectus, the first ancestor to leave Africa and colonize the globe. What led to this first great African exodus?
0.0Blue 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.
7.040, 000 years ago the steppes of Eurasia were home to our closest human relative, the Neanderthals. Recent genetic and archaeological discoveries have proven that they were not the dim-witted cave dwellers we long thought they were. In fact, they were cultured, technologically savvy and more like us than we ever imagined! So why did they disappear? We accompany scientists on an exciting search for an answer to this question and come to a startling conclusion …
7.5The great follow-up to 'Walking with Dinosaurs' and 'Walking with Beasts', presented by Professor Robert Winston, explains the story of human evolution.
7.1Explores the story behind the discovery of an early primate fossil, Darwinius masillae, nicknamed Ida, in a shale quarry in Germany. The fossil is believed to be around 47 million years old, and is extraordinarily well-preserved. Originally unearthed in 1983, Ida lay in the hands of a private collector for 20 years before it was shown to a Norwegian paleontologist, Dr Jørn Hurum. Realising that Ida could turn out to be a significant missing link between modern primates, lemurs and lower mammals, he persuaded the Natural History Museum in Oslo to purchase the fossil and assembled an international team of experts to study it. Their findings were announced in a press conference and the online publication of a scientific paper on 19 May 2009.
5.0Long before the arrival of Homo Sapiens, the Neanderthals wandered the vast European plains, and regularly drowned into the Ice Ages. Several discoveries, in France and England, and especially on the island of Jersey, now allow archaeologists to understand the lifestyle of those first great nomads of Europe, that lasted 300.000 years.
8.5A brief visualisation of NASA’s historic spacecrafts Mariner, Pioneer, Voyager, and Dawn, exploring the solar system, culminating in the New Horizons mission.
6.0Astrophysicist Jean Surdej brings a small group of teenage pupils on a trip to the Lofoten islands in northern Norway, for a very special class on the solar system. Using the geography of the archipelago to illustrate the distances between the planets, they journey through space by car and ferry, with the picturesque landscapes standing in for the black emptiness that surround the heavenly bodies. A masterstroke of both pedagogy and filmmaking, Children of Stars is a captivating documentary about humanity's place in the grand scheme of things.
