The world of bugs normally passes beneath our notice, yet shrink yourself to their size, see them in 3D and you’ll enter a world you’d never believe existed. Big Bugs in 3D uses specially developed 3D technology to take the viewer on a global journey, from Mexico and the rainforests of Asia to our own backyards. There are perhaps four and a half million different kinds of bugs sharing the planet with us. They exist in a bewildering variety of forms, some more like creatures from an alien world. Big Bugs asks how and why these creatures have become so successful.

Carlsbad Caverns are located in the Chihuahuan Desert of southern New Mexico, within the Carlsbad Caverns National Park. There are more than 100 caves. The Natural Entrance is a path into the namesake Carlsbad Cavern. Stalactites cling to the roof of the Big Room, a huge underground chamber in the cavern.

It's a natural history epic. It's a compelling detective story. It's a scientific adventure at its best. It took Dr Fred Urquhart almost 40 years to discover the monarch butterflies' secret hideaway and prove the most incredible migration on Earth. Following the year-long annual migration cycle of the butterflies, the award-winning production team filmed hundreds of millions of monarchs in their remote overwintering sanctuaries in Mexico in 2011 and again in 2012 and also along their migratory routes from Canada, across the U.S. and into Mexico. The film immerses you in the astounding migration experience as two generations of the butterflies migrate north and then a Super Generation miraculously finds its way from Canada to a few isolated mountaintops in Mexico.

Experts suspect that the dinosaurs were wiped out after a city-sized asteroid smashed into the Gulf of Mexico causing a huge crater. But until now, they haven't had any proof. In a world first, evolutionary biologist Ben Garrod joins a multi-million pound drilling expedition into the exact spot the asteroid hit to get hard evidence of the link. The team overcomes huge obstacles as it attempts to drill 1,500 metres beneath sea level to pull up rock from the Chicxulub crater. Meanwhile, paleopathologist Professor Alice Roberts travels the globe meeting top scientists and gaining exclusive access to a mass fossil graveyard in New Jersey - believed to date from the same time the asteroid hit. Alice also treks by horseback across the remote plains of Patagonia, to see if the effects of the asteroid impact could have wiped out dinosaurs across the world - almost immediately.

A global adventure of science and discovery--featuring the earliest dinosaurs of the Triassic Period to the monsters of the Cretaceous 'reincarnated' life-sized for the screen. Audiences will journey with some of the world's preeminent palaeontologists as they uncover evidence that the descendents of dinosaurs still walk (or fly) among us. From the exotic, trackless expanses and sand dunes of Mongolia's Gobi Desert to the dramatic sandstone buttes of New Mexico, the film will follow American Museum of Natural History palaeontologists as they explore some of the greatest dinosaur finds in history. Through the magic of scientifically accurate computer-generated animation, these newly discovered creatures, and some familiar favourites, will come alive... in a big way!

From the Philippines to the US, Madagascar and Mexico, Professor Brian Cox explores the globe to reveal how a few fundamental laws of science gave birth to the most complex and unique feature of the universe - life. In the first episode, Brian journeys to the volcanic landscapes of South-East Asia, seeking to understand how life first began and how that spark has endured to this day.
