The Infinite Monkey Cage

Under The Night SkyBrian Cox and Robin Ince discover the importance of the night sky to human history and how our relationship with the stars has changed over the centuries. They are joined by star-gazer Jon Culshaw, astronaut Tim Peake, astrophysicist Lisa Harvey-Smith and astronomy writer Stuart Clark as they chart the changing nature of our relationship with the sky above us. They discuss ancient cave paintings depicting Orion's belt, the astronomical revolution that came with our understanding of how planets orbit the Sun, and how astronauts like Tim who have "touched the sky" have seen the stars in a totally unique way. Has our ever expanding knowledge about the stars twinkling above us removed some of the magic, or have modern missions and the incredible images of space we now see brought us closer, quite literally, to the sky above us?Producer: Alexandra Feachem

In Praise of FliesBrian Cox and Robin Ince kick off a new series of Infinite Monkey Cage with a look at probably the least revered or liked group of insects, the flies. They are joined by fly sceptic David Baddiel , fly enthusiast and champion Dr Erica McAlister and maggot expert Matthew Cobb to discover why a life without flies would be no life at all. Can Erica and Matthew persuade David to put his fly gun down and learn to love those pesky pests, or is their reputation for being disgusting and annoying justified? What would a planet without flies look like?Producer: Alexandra Feachem

Brian Cox and Robin Ince are joined by actor and writer Mark Gatiss, theoretical physicists Carlo Rovelli and Fay Dowker to ask timely questions about time. Is time real, does it exist in the fundamental laws of physics, and if it doesn't, why do we experience the sensation of time passing? They look at the idea of the block universe, where our future is as real as our past, which worryingly leads to Robin's favourite question about free will...is that an illusion too? A timely look at the question of time and hopefully just in time...Producer: Alexandra Feachem

Brian Cox and Robin Ince are joined by comedians Jo Brand and Ross Noble, alongside Nobel Prize winner Sir Paul Nurse and geneticist Prof Aoife McLysaght to ask the biggest question of all, what is life and how did it start? They look at the amazing feat of nature that has somehow created all of life from just four fundamental units of simple chemistry. From chickens to butterflies to yeast, we are all far more closely related then we think. But how did the spark of life occur and what has any of this got to do with Ewoks? Producer: Alexandra Feachem

Brian Cox and Robin Ince are joined by Dr Jane Goodall DBE, comedian Bill Bailey and primatologist Dr Cat Hobaiter to find out what we've learnt in the 60 years since Jane first discovered the chimpanzees of Gombe. From tool use, to language and even to culture, her revolutionary work has transformed our understanding of our great ape cousins, and ourselves. The panel chat about how far our understanding has come in that time, and talk about their own unique close-up experiences of chimpanzees, macaques and baboons, and Bill gets a masterclass in how to speak Chimp from a true expert!Producer: Alexandra Feachem

Brian Cox and Robin Ince are joined by a dazzling panel of sun worshippers from actor, comedian and musician Tim Minchin to solar scientist Professor Lucie Green and biologist Professor Steve Jones. They look at how the evolution of life was only possible because of our position relative to the sun and its possibly unique behaviour, and how rare that situation might be across the rest of the universe. They also look at how the sun makes you feel and its vital importance to all creatures, especially snails.Producer: Alexandra Feachem

Brian Cox and Robin Ince are joined by a stellar panel of space travellers as they get tips on surviving isolation from a group with a truly unique insight. They are joined by astronauts Helen Sharman, Chris Hadfield, Nicole Stott and Apollo 9's Rusty Schweickart to talk Space X, the future of space travel and how a trip to Mars will be the ultimate test of our ability to survive isolation.

Brian Cox and Robin Ince are joined by comedian and writer Sara Pascoe, biological anthropologist Alice Roberts and space archaeologist Sarah Parcak. They look at how archaeology today looks far more Star Wars than Indiana Jones, as an archaeologist's list of kit can now include satellites and lasers. They discover how searching for clues from space has led to the discovery of several ancient lost Egyptian cities and how the study of ancient DNA and artefacts reveals our similarities, not differences, with our ancient forebears. Producer: Alexandra Feachem

Brian Cox and Robin Ince look at the weird and wacky world of black holes as they ask a question that has been troubling scientists for years: What happens if you push Matt Lucas into a black hole? They are joined by the very game Matt Lucas, alongside cosmologist Sean Carroll and astrophysicist Janna Levin to discover just how strange things might get for our intrepid volunteer, as he ventures into the interior of a black hole. From holograms to spagettification. it turns out science fact is far more bizarre than anything that science fiction could possibly imagine. Producer: Alexandra Feachem

Brian Cox and Robin Ince are back for new series, for now at least, as they take an upbeat look at all the different ways our Universe might end. They are joined by legendary comedians Steve Martin and Eric Idle, alongside astrophysicist Katie Mack and cosmologist Brian Greene, to find out which end the panel might prefer. Will we go with the Big Rip or possibly the Big Crunch, or even death by giant bubble that expands so rapidly it wipes out our universe almost instantly? On that cheery note the panel vote for their favourite apocalyptic ending and wonder what they might be doing and what they hope to have achieved when the final moment comes.Producer: Alexandra Feachem

UFO SPECIALBrian Cox and Robin Ince host a close encounter of the 1st kind with comedian Lucy Beaumont, astronomer Maggie Aderin-Pocock, Director of Jodrell Bank Professor Tim O’Brien, and science presenter Dallas Campbell to ask if UFOs and aliens have visited Earth? They explore why Lucy's home city of Hull appears to have had more than its fair share of alien visitations, as well as learning about the genuine scientific effort to look for intelligent life elsewhere in our universe. This episode is also available to watch, so you can see our truly out of this world panel in full technicolour glory. Just look for The Infinite Monkey Cage UFO TV Special on BBC iplayer.Producer: Alexandra Feachem

Brian Cox and Robin Ince send comedian Lucy Beaumont to investigate UFO sightings in the extra-terrestrial hotspot of... Hull! Lucy is joined by her mum GIll Adams who claims to have experienced a number of close encounters of the third kind and they return to Longhill Estate where a UFO was reported in the 1960s. Local historian Mike Covell takes Lucy through the documented accounts of prolific UFO sightings in and around the East Yorkshire area.

Quantum WorldsBrian Cox and Robin Ince are joined by comedian Katy Brand, and physicists Sean Carroll and Jim Al-Khalili as they enter the strange and bizarre world of quantum mechanics. Schroedinger's famous thought experiment stuck a cat in a box and asked if it is dead or alive. Quantum physics says the cat is both dead and alive, until we open the box. This mind-bending idea may seem the realm of philosophy, but is actually the science that underpins most of modern life as we know it. Once the panel have dealt with the controversial issues surrounding cats in boxes, they explore whether quantum physics is really an accurate description of reality, and if it is, are there, as the theory suggests, infinite copies of you, me and everything in our universe all existing in every possible combination of ways of existing? If that is the strange but true reality of existence, will we ever be able to prove it?

Fire!Brian Cox and Robin Ince are joined by comedian Ed Byrne, forensic chemist Niamh Nic Daeid and biologist Adam Rutherford, as they explore the science of fire and how it has impacted the evolution of life on earth. They also look at whether controlling fire is a uniquely human trait and how other species have evolved to use fire to their advantage.Producer: Alexandra Feachem

The Magic of CoralBrian Cox and Robin Ince are joined on stage by comedian Marcus Brigstocke and marine biologists Professor Callum Roberts and Dr Heather Koldewey as they look at the amazing creatures that create and colonise coral reefs. Just two microscopic organisms are responsible for the creation of these incredible structures, structures so huge that they can be seen from outer-space. Brian, Robin and the panel talk about the vital yet delicate relationship between the coral polyp and and its tiny plant lodger, how they evolved to be so co-dependent, and how this unique partnership has lead to some of the most diverse ecosystems on the planet. They also look at the very real threat to our planet's reefs as our oceans warm, and what, if anything can be done.Producer: Alexandra Feachem

Brian Cox and Robin Ince are joined on stage by comedian Shazia Mirza, science writer and cancer researcher Dr David Robert Grimes and psychologist Prof Karen Douglas to look at the weird world of conspiracy theories. From Flat Earth believers to people who refuse to accept that humans have ever been to the moon, why is fiction often so much easier to believe than fact - and does it matter? They discuss the psychology and profile of people who are more likely to believe in conspiracies and the devastating effect some, like the anti-vaccine movement, have had on public health. They ask whether being irrational is our default setting and how to convince the most hard-core believers with the power of evidence and critical thinking. Although they would say that wouldnt' they? Producer: Alexandra Feachem

The Science of LaughterBrian Cox and Robin Ince return for a new series of science/comedy chat. They are joined on stage, appropriately enough, by comedian Frank Skinner, as they look at the science of what makes us laugh, why we laugh at all, and whether humour and laughter are uniquely human traits. Joining the panel are experts in what makes us chuckle, Prof Sophie Scott and Professor Richard Wiseman. They look at why laughter is not only an ancient human trait that goes a long way to making us the social animal we are today, but that rats and apes also enjoy a good chuckle. They discover whether science can come up with the perfect joke and why a joke with the punchline "quack" is funnier than one with the punchline "moo". Producer: Alexandra Feachem

Brits in Space!Brian Cox and Robin Ince are joined by astronaut and author of "The Astronaut Selection Test Book", Tim Peake, first British astronaut Helen Sharman and comedian Mark Steel for a Brits in Space Special. Tim and Helen talk about their different experiences of training to be an astronaut and the challenges of life in space. They also look to the future as the panel talk about the various options being considered for long term space flight with planned future missions to the Moon and ultimately Mars.

The Periodic Table How well do you know your Fe from your Cu, and what the heck is Np?? Brian Cox and Robin Ince are joined by comedian Katy Brand, Prof Polly Arnold and Prof Andrea Sella to celebrate the 150th anniversary of Dmitri Mendeleev's great achievement. They find out how scientists first realised that the elements that form the ingredients that make up our planet , are able to be organised in such a logical and ordered way, and whether its still a useful tool today. They also discover why one of the guests has been called the Free Solo equivalent of chemists because of the skill and danger involved in their work. Producer: Alexandra Feachem

Brian Cox and Robin Ince are joined by comedian Bridget Christie, neuroscientist Professor Penny Lewis and psychologist Richard Wiseman to explore the science of dreaming. Our dreams have fascinated humans for millennia and then Freud came along and told us they really did mean something, and mostly they were about sex and anger. Was he right? Why do we dream and can we find meaning in the content of our dreams? Can our dreams help us solve problems, give us new ideas, help us write a symphony, even if they can't predict the future? The panel also discuss what is going on in the brain whilst we sleep, and how memories are formed and consolidated while we snooze. It turns out the phrase "better to sleep on it" has a strong scientific argument.Producer: Alexandra Feachem

Those Clever CreaturesBrian Cox and Robin Ince are joined on stage by comedian and author Danny Wallace, ornithologist Professor Tim Birkhead and marine biologist Helen Scales to look at animal intelligence. We have all heard about clever chimps that can count, and about how we can compare the intelligence of humans and the great apes - but have we underestimated many of the other animal species? It would seem so, with remarkable examples of cunning, smart behaviour from animals as diverse as birds, octopuses and even fish. So how do you test a guppies IQ and can a crow really outsmart a gorilla, or even a human...prepare to be amazed. Producer Alexandra Feachem

Brian Cox and Robin Ince return for a new series of their multi-award winning science/comedy show. They kick off with arguably any child's first interest in science - dinosaurs! They are joined by comedian Rufus Hound and palaeontologists Susannah Maidment from the Natural History Museum and Steve Brusatte from the University of Edinburgh to find out what the latest research and exciting fossil finds have revealed about these epic creatures. Are we in a new age of dinosaur discovery? What are the big questions that dinosaur hunters are hoping to uncover, and did they go extinct at all? Producer: Alexandra Feachem

A special hour long episode of the hugely popular science/comedy show, celebrating the 50th Anniversary of the Apollo moon landings. Recorded at Cocoa Beach, Florida just down the road from Cape Canaveral, Brian Cox and Robin Ince are joined by some of the key players involved in landing the first people on the moon, on this day, 1969. Apollo 9 Astronaut Rusty Schweickart, Apollo flight director Gerry Griffin and Apollo children Jan and Andy Aldrin give their perspectives on arguably one of the greatest scientific and engineering achievements of all time. Keep listening for a very special guest appearance by Duran Duran's Nick Rhodes.Presenters: Brian Cox and Robin Ince Producer Alexandra Feachem

How to Measure the UniverseBrian Cox and Robin Ince are joined on stage by comedian Jo Brand, and physicists Prof Jo Dunkley and Dr Adam Masters to look at how we go about measuring our universe, from measuring the contents of atmospheres of planets and moons at the outer edges of our solar system to looking far back in time to study the very earliest beginnings of the cosmos. Our ability to learn about phenomena and worlds that seem almost impossibly out of reach, now give us an incredible insight into the universe we occupy, and how we got here. Brian and Robin find out about some of the big new missions providing information into our own solar system and beyond, and find out what big questions in cosmology still remain a tantalising challenge?Producer: Alexandra Feachem

How to Build a Bionic Human.Brian Cox and Robin Ince are joined on stage by "supervet" Noel Fitzpatrick, Dr Kevin Fong and comedian Lucy Beaumont to learn how to build a bionic human. They'll be looking at the development of artificial limbs and organs that have been pioneered during times of war and at the extreme end of emergency medicine, and find out how Noel Fitzpatrick is developing new techniques and bionic devices at his veterinary practice, that could eventually be used on humans.

Are humans still evolving?Brian Cox and Robin Ince are joined by comedian and author David Baddiel, Professor of Evolutionary Genetics Aoife McLysaght, and geneticist and broadcaster Adam Rutherford to ask whether human beings are still evolving? Has the invention of modern medicine, and technology meant that survival of the fittest is a thing of the past or are humans evolving new adaptations that will help us cope and survive better in our ever changing world (better thumbs for texting anyone?). If evolution happens over 1000's of years, could we even tell if we were evolving as a species, or have humans reached peak human?Producer: Alexandra Feachem

The origin of numbers and can fish count?Brian Cox and Robin Ince are joined by mathematician Dr Hannah Fry, comedian Matt Parker and neuroscientist Prof Brian Butterworth to ask where numbers come from and can fish count? They'll be looking at the origin of numbers and whether counting is a uniquely human trait that actually started before the evolution of language.

The Future of Humanity Brian Cox and Robin Ince take on the entire future of our civilisation, as they are joined by Astronomer Royal and former head of the Royal Society Lord Rees, Baroness Cathy Ashton and comedian, actor and director Chris Addison. They'll be talking about the biggest challenges facing humanity at the moment, and whether science offers the solution to some of these great problems, from Climate Change to the rise of AI.

Microbes: Secret Rulers of the World?Brian Cox and Robin Ince return for a new series of the hugely popular, award-winning science/comedy show. This week they are joined by comedian Ed Byrne, oceanographer Dr Jon Copley and planetary scientist Prof Monica Grady to ask whether the real master-race on planet Earth is not human but microbe. They'll be looking at how microbes are found in every extreme environment on the planet, how and when they first arrived on the Earth and why the hunt is on to find evidence of microbes in space.

The Code BreakersBrian Cox and Robin Ince are joined by comedian Katy Brand, as they transport the cage of infinite proportions to the home of modern day cryptography and codebreaking., GCHQ. They'll be discovering how far we've come from the days of the humble code book and the birth of machines like Enigma. and how the new digital era has turned us all into modern day code breakers and cryptographers, without us even realising it. Producer: Alexandra Feachem.

Brian Cox and Robin Ince reminisce about their favourite moments from 100 episodes of The Infinite Monkey Cage.

The Human VoiceBrian Cox and Robin Ince are joined by comedian and beatboxer Beardyman, acoustic engineer Prof Trevor Cox and neuroscientist Prof Sophie Scott to explore the amazing capabilities of the human voice. They chat about chatting, vocalise about voices and explore the extraordinary and unique way the human voice works from opera singing to laughter, and discovery why our voice has been so key to our success and survival as a species. Producer: Alexandra Feachem.

The Immune SystemBrian Cox and Robin Ince are joined by comedian Shappi Khorsandi, Prof Dan Davis and Prof Steve Jones to look at our amazingly complex and clever immune system. They look at how the human body fights disease, and why it has been so little understood until now. Fear not though, a new revolution in understanding is underway, with some extraordinary insights into the cunning of our little white cells. The panel look at how this new understanding is already leading to some real breakthroughs in treatment for diseases such as cancer, and Shappi reveals the crucial role she played in one such discovery.Producer: Alexandra Feachem.

Invasion!Brian Cox and Robin Ince are joined by comedian Phill Jupitus, bat expert and ecologist Professor Kate Jones and forensic botanist Dr Mark Spencer to look at the problems caused by alien invasions, although not of the little green men kind. They look at why such innocent and innocuous sounding plants such as floating pennywort strike terror and fear in the heart of environmentalists up and down the country, and how clever microbes and diseases are able to jump from animals such as bats to humans causing devastating consequences. Producer: Alexandra Feachem.

Brian Cox and Robin Ince are joined on stage by Danny Wallace, mathematician Hannah Fry and science writer Timandra Harkness. They'll be going big on Big Data, and asking just how big is it? They'll be looking at where Big Data comes from, should we be worried about it, and what mysteries are hidden within the seemingly endless amounts of information that is collected about us as we go about our daily lives.

Monkey Cage 100!Brian Cox and Robin Ince celebrate the 100th episode of the hit science/comedy show, by inviting some very well known monkey cage alumni to join them. Brian Blessed, Eric Idle, Katy Brand, Dave Gorman and Andy Hamilton (to name a few) take to the stage to consider what has been learnt since Episode 1, back in November 2009. Joining them on stage, will be science royalty, including Alice Roberts, American Astrophysicist Neil De Grasse Tyson, Professor Sue Black and Prof Fay Dowker, to look at the big scientific discoveries that have happened in the time since Brian and Robin first hit the airwaves, from the Higgs Boson, to Gravitational Waves, to our understanding of how human evolved. What epic discoveries might be made over the course of the next 100 episodes? For the first time, You can watch the 100th episode of The Infinite Monkey Cage, recorded live in the iconic BBC Radio Theatre, on BBC iPlayer for 30 days from Wednesday July 11th, and on the BBC Red Button at various times for 7 days from Monday 16th July.Producer: Alexandra Feachem Producer (Vision): Michael Gray.

Volcano!Brian Cox and Robin Ince are joined by comedian Jo Brand and Volcano experts Professor Tamsin Mather and Professor Clive Oppenheimer. They look at the very latest technology that is used to predict the next big volcanic eruption, as well as the history and importance of volcanoes and volcanic activity on our planet. Producer: Alexandra Feachem.

How Animals BehaveBrian Cox and Robin Ince are joined by comedian Rufus Hound, Zoologist and broadcaster Lucy Cooke and Professor Rory Wilson to discover how we learn about what animals are up to when we are not looking, and some of the hilarious mistakes we've made in the process of discovery. They'll be hearing about why the sex life of eels has remained so enigmatic, how the mystery of the wandering albatross has been solved, and why making underwear for frogs finally solved the riddle of how babies are made.

The Teenage BrainBrian Cox and Robin Ince are joined by impressionist Rory Bremner, Professor of Cognitive Neuroscience at UCL Sarah-Jayne Blakemore and Professor of Zoology at Manchester University Matthew Cobb to look at the working of the teenage brain, and why teenagers are so, well, teenagery. Stomping off to your bedroom, being embarrassed by your parents, wanting to fit in with your peers and a love of risky behaviour are all well known traits associated with our teenage years, exasperating parents through the ages. But new research into dynamic changes going on in the brain during these key years has revealed that it's not just hormones that are responsible for these behaviours. Could a better understanding of what is going on during these formative years not only help teenagers themselves, but inform our education system and even help prevent many of the mental health problems that often begin during adolescence?

Antibiotics Brian Cox and Robin Ince are joined by comedian Chris Addison, Chief Medical Officer, Dame Sally Davies, and Professor Martha Clokie to look at the history and future for antibiotics. Producer: Alexandra Feachem.

The Secret Life of BirdsBrian Cox and Robin Ince are joined by guests including Katy Brand, Steve Backshall and Professor Tim Birkhead to uncover the secret life of birds. They'll be looking at some of the extraordinary and cunning behaviour exhibited by many species of birds, both male and female, in an effort to attract a mate. They also get a special visit from Brann the Raven, who takes to the stage to demonstrate just how intelligent some species of birds can be. Producer: Alexandra Feachem.

When Two Stars CollideBrian Cox and Robin Ince are joined on stage by comedian Dara O'Briain, Professor Sheila Rowan of Glasgow University and Professor Nils Andersson of Southampton University to look at last summer's spectacular discovery of gravitational waves from two colliding neutron stars. The observation of this huge cosmic event not only confirmed one of Einstein's great predictions, some 100 years ago, but also revealed the source of gold in our universe. Brian, Robin and guests look at how this momentous discovery brought together nearly 1/3 of the world's astronomers and astrophysicists as they raced to point their telescopes at the collision, but also confirmed the presence of gravitational waves, first predicted in Einstein's theory of general relativity back in 1915. They also discover why the source of our heavier elements such as gold and platinum has been so difficult to prove, until now. Producer: Alexandra FeachemThe Infinite Monkey Cage book "How to Build A Universe (Part 1)" is out now and available to buy from all the usual places.

The Infinite Monkey Cage Christmas Special: The Science of MagicThe Infinite Monkeys bring their own brand of yule friendly science and comedy to the BBC Radio 4 Christmas schedule, and this year add an extra sprinkling of festive magic. Brian Cox and Robin Ince will be joined on stage by some very special guests to look at the science behind some of our best loved magic tricks and illusions. Actor, writer and illusionist Andy Nyman,actor and comedian Diane Morgan, Professor of Psychology and magician Richard Wiseman, and theologian and broadcaster Professor Francesca Stavrakopoulou will all be demonstrating how basic human psychology and evolution allow us to see and believe the seemingly impossible. They'll be exploring how some basic psychology can lead to some truly impressive deceptions, and ask how easy it is to trick the human mind, even a mind like Brian's. Prepare to be amazed.Producer: Alexandra Feachem.

The Mind V The Brain.It's one of the hardest problems in neuroscience. How do the chemical processes and electric signals produced by our brains result in the complex and varied experiences and sense of self that we might describe as our mind? Brian Cox and Robin Ince are joined on stage by comedian Katy Brand, and neuroscientists Professor Uta Frith and Professor Sophie Scott to ask whether the mind is simply a product of the biology of our brain, or is there more to it than that? Can you have a brain without a mind, and is the mind simply an unexpected consequence, an emergent property, of our highly evolved and sophisticated brain. They'll also be tackling the question of free will, and whether we really have any, and if you could in theory simulate a fully working brain, with all its signals and complexity, would a mind naturally emerge?Producer: Alexandra Feachem.

Are we living in a simulation?Elon Musk thinks we definitely could be, and it seems he is not alone. The idea that we might simply be products of an advanced post-human civilisation, that are simply running a simulation of our universe and everything it contains, has taken hold over the last few years. Brian Cox and Robin Ince are joined on stage by comedian Phill Jupitus, Philosopher Professor Nick Bostrom and Neuroscientist Professor Anil Seth to ask what the chances are that are living in some Matrix like, simulated world and more importantly, how would we ever know?Producer: Alexandra Feachem.

Will Insects Inherit the Earth?Brian Cox and Robin Ince are joined on stage by comedian Dave Gorman, zoologist Tim Cockerill and forensic entomologist Amoret Whitaker. They'll be discovering the joy of creepy crawlies, why the flea is the ultimate master of Darwinian evolution, and whether those pesky cockroaches will really have the last laugh if we are unlucky enough to be wiped out by a nuclear explosion. They'll be discovering how and why insects have been by far the most successful group of organisms during the history of life on planet earth, and why we simply couldn't do without them.

Oxygen: a matter of life and death.Brian Cox and Robin Ince are joined on stage by chemist Andrea Sella, science broadcaster and writer Gabrielle Walker and comedian Sara Pascoe to look at the life and death properties of oxygen. It's the molecule we simply can't live without, but as fate would have it, oxygen is also the molecule that eventually leads to our death. Hailed as an elixir of life, and foundation of the atmosphere, oxygen is the revolutionary element that quickens life and hastens death through its ferocious reactivity. It's the molecule our cells need, but is actually highly toxic to them, and is in the end what causes us to age. Brian and Robin get to grips with the chemistry of this contradictory molecule, and Andrea Sella tries not to cause too big an explosion by demonstrating oxygen's reactive nature using a digestive biscuit. Producer: Alexandra Feachem.

Astronaut SpecialBrian Cox and Robin Ince transport the cage to Trondheim Norway, host of this year's Starmus Festival, for an extraordinary gathering of astronauts. They are joined on stage by NASA astronauts Sandra Magnus and Terry Virts, ESA astronaut Claude Nicollier, and Apollo 16's Charlie Duke, one of the last people to have walked on the moon. They talk about their personal journeys to fulfill their long-held dreams, and literally reach for the stars. They hear from Charlie Duke about the extraordinary Apollo missions he was part of, including his role as Capsule Communicator for the very first moon landing, before taking his own first steps on the lunar surface as part of Apollo 16. They explore the different experience of astronauts from Charlie's era, and those who now become residents of space, spending months and months aboard the International Space Station, and the challenges each mission brings. And Claude Nicollier describes his epic spacewalk to repair the Hubble Telescope. Producer: Alexandra Feachem.

"What Particles Remain to be Discovered?"Brian Cox and Robin Ince return for a new series of the hugely popular, multi-award winning science/comedy show. Over the series a variety of scientists and comedy science enthusiasts will take to the stage to discuss everything from the glory of insects to whether free will is just an illusion. They'll be joined by the usual eclectic selection of guests over the series, including comedian Sara Pascoe, Dane Baptiste, Katy Brand and Eric Idle, as well as astronauts Sandra Magnus and Apollo astronaut and moon walker Charlie Duke, for a space traveller special.The first show will see Python legend and Monkey Cage theme tune creator Eric Idle take to the stage alongside physicists Jonathan Butterworth and Catherine Heymans to ask "what particles remain to be discovered?" . They'll be looking at life beyond the Higgs Boson and asking whether a new, as yet undetected particle could answer arguably the greatest question in physics and finally uncover the mysterious unknown elements that make up the 95% of our Universe that are known as Dark Matter and Dark Energy.

Making the Invisible, Visible Brian Cox and Robin Ince are joined by comedian Katy Brand, Cosmologist Prof Carlos Frenk, and biologist Prof Matthew Cobb to discover how to make the seemingly invisible, visible. They look at how the history and development of the telescope and the microscope have allowed us to look at the impossibly big to the seemingly impossibly small, to gain insight into the history of our universe and the inner workings of the human body. They look at how radio and space telescopes have allowed us to look back in time and "see" the big bang, and understand the age and content of the early universe, and how space telescopes have thrown light on the mysterious substance known as dark matter. They also look at the way microscopes and new biological techniques have allowed us to understand the seemingly invisible processes going on inside our cells. They also ask what, if anything, will always remain invisible to us - are there some processes or concepts that are impossible for us to "see". Producer: Alexandra Feachem.
