How can scientists study a faraway black hole that emits no light? By observing its quasar. As objects get pulled onto the accretion disk orbiting a supermassive black hole, friction creates a bright light known as a quasar. In this video, researchers use a “galaxy-sized lens” to analyze light from a distant quasar—revealing a supermassive black hole with a truly voracious appetite.

Amidst radical changes in nicotine use globally, one filmmaker's journey through the confusion & fear leads to a startling discovery about Earth's most hated stimulant. Society may be changed forever.
Tobacco, climate change, pesticides,... Never has scientific knowledge seemed so vast, detailed and shared. And yet it appears to be increasingly challenged. It is no longer surprising to see private corporations put strategies in place to confuse the public debate and paralyze political decision-making. Overwhelmed by excess of information, how can we, as citizens, sort out fact from fiction? One by one, this film dismantles the workings of this clever manoeuvre that aims to turn science against itself. Thanks to declassified archives, graphic animations and testimonies from experts, lobbyists and politicians, this investigation plunges us into the science of doubt. Along with a team of experts (philosophers, economists, cognitive scientists, political men, or even agnotologists), we explore concrete examples of doubt making and try to understand the whole process and the issues behind it.
Wildlife photographer Richard Sidey joins an international team of whale research scientists in Antarctica to document their work on how Humpback Whales are adapting to a changing ocean.
An African narrator tells the story of earth history, the birth of the universe and evolution of life. Beautiful imagery makes this movie documentary complete.
This documentary examines theories behind the creation of gamma ray bursts, destructive explosions in space that can wipe out entire star systems.
Fascinating -- and unintentionally funny -- experiments at Austria's famed Institute for Experimental Psychology involve a subject who for several weeks wears special glasses that reverse right and left and up and down. Unexpectedly, these macabre and somehow surrealist experiments reveal that our perception of these aspects of vision is not of an optical nature and cannot be relied on, while the unfortunate, Kafkaesque subject stubbornly struggles through a morass of continuous failures.
Prof. Jim Al-Khalili tackles the biggest subject of all, the universe. Through a series of critical observations and experiments that revolutionised our understanding of our world Jim guides us through the greatest cosmic detective story of all. He takes us from the beginning of the universe to the end time and answers the question: where did the universe come from and how will it end?
The Scorpions belong to the oldest land-based arachnides with over 1800 different species known to exist. Usually, they do not surpass the size of 10cm in length, but exceptions are know, such as the Emperor Scorpion (Pandinus imperator) which can grow up to become over 20cm in size. Scorpions are mostly active at night and hide away during the day. Take a look into the live of these amazing creatures!
A celebration of the universe, displaying the whole of time, from its start to its final collapse. This film examines all that occurred to prepare the world that stands before us now: science and spirit, birth and death, the grand cosmos and the minute life systems of our planet.
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.
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.
From Raymond Baxter live on Tomorrow's World testing a new-fangled bulletproof vest on a nervous inventor to Doctor Who's contemporary spin on the War on Terror, British television and the Great British public have been fascinated with the brave new world offered up by science on TV. Narrated by Robert Webb, this documentary takes a fantastic, incisive and funny voyage through the rich heritage of science TV in the UK, from real science programmes (including The Sky At Night, Horizon, Tomorrow's World, The Ascent of Man) to science-fiction (such as The Quatermass Experiment, Doctor Who, Doomwatch, Blake's 7, The Hitchhiker's Guide to the Galaxy), to find out what it tells us about Britain over the last 60 years.
Dr Helen Czerski delves into the Horizon archive to chart the transformation of a little-known theory into one of the greatest scientific undertakings in history.
Of the Seven Wonders of the Ancient World, the Pyramid is the only one to survive. Many believe that even with our 21st-century technology, we could not build anything like it today. Based on the most up-to-date research and the latest archaeological discoveries, here is how the Pyramid came to be.
Chaos theory has a bad name, conjuring up images of unpredictable weather, economic crashes and science gone wrong. But there is a fascinating and hidden side to Chaos, one that scientists are only now beginning to understand. It turns out that chaos theory answers a question that mankind has asked for millennia - how did we get here?
An examination of the extinction threat faced by frogs, which have hopped on Earth for some 250 million years and are a crucial cog in the ecosystem. Scientists believe they've pinpointed a cause for the loss of many of the amphibians: the chytrid fungus, which flourishes in high altitudes. Unfortunately, they don't know how to combat it. Included: an isolated forest in Panama that has yet to be touched by the fungus, thus enabling frogs to live and thrive as they have for eons.
Four young Americans who've each suffered a Traumatic Brain Injury emerge from their comas at a New Jersey medical facility. Their eyes may be open, but now the real challenge for each of the patients, their families, their doctors and their therapists begins. Brain healing isn't predictable, we're told, and certainly is not guaranteed. So with each 'major' step forward that is observed (opening one's eyes, bending a thumb upon command, vocalizing a word, answering a question correctly) comes a sense of jubilant relief and hope from the families of these patients, but as we soon see, the more a patient progresses, the more difficult things can be for all involved. Moments of faith & hope contrast with disappointments & frustrations, moments of confidence with moments of doubt. It's difficult to watch, and unimaginable to have to ever live through.
Concern over global climate change may be at an all-time high, but climate change is nothing new - the earth's climate always followed natural cycles of warming and cooling. In Unstoppable Solar Cycles, Dr. Willie Soon and Dr. David Legates challenge the popular idea that human-generated CO2, is causing catastrophic global warming. These scientists propose an alterantive theory - that the current warming has more to do with solar activity than with human activity.
Most people fully accept paranormal and pseudoscientific claims without critique as they are promoted by the mass media. Here Be Dragons offers a toolbox for recognizing and understanding the dangers of pseudoscience, and appreciation for the reality-based benefits offered by real science.
