Between the blue sky above and the infinite blackness beyond lies a frontier that scientists have only just begun to investigate. In "At the Edge of Space," NOVA takes viewers on a spectacular exploration of the Earth-space boundary that's home to some of nature's most puzzling and alluring phenomena: the shimmering aurora, streaking meteors, and fleeting flashes that shoot upwards from thunderclouds, known as sprites.

MasterChef judge Gregg Wallace and mathematician Dr Hannah Fry take over a restaurant and invite five special guests to enjoy a dinner party with a difference, where they will be scored on the carbon footprint of every dish they choose. Food accounts for a third of all greenhouse gas emissions, so making informed choices about what we eat is more important than ever. Diners Sara Pascoe, Amol Rajan, Nikki Fox, Desiree Burch and Matthew Fort choose from a menu of tantalising treats, each of which tells its own environmental story. But will they be able to sort the eco-goodies from the eco-nasties hidden in each course? Gregg is with the kitchen team preparing delicious dishes and uncovering tips and tricks we can all use to cook more sustainably. Hannah is working with environmental scientists to reveal the carbon footprint of every single item on the menu and uncovering the latest research that can help us enjoy the food we love that doesn't cost the Earth.

The Great Lakes region provided geologists with much of the evidence for the frequent ice ages that visited North America. But the lakes may be a rather transient feature of the continent dependent upon the recurring ice ages to maintain their existence.

This episode focuses on the Asia-Pacific side of The Pacific Rim of Fire, which stands as a living testament to the beauty and danger that powerful geologic forces can deliver. The Pacific Rim is home to half of the world's active volcanoes and ninety percent of the world's earthquakes, yet nearly 800 million people continue to live within its violent edge. Our journey begins in New Zealand, a land of volcanoes and earthquakes, where we find a 500-kilometre long slip-strike fault deep under the Pacific Ocean. Geologist Hamish Campbell will take us to the crater of White Island, the country’s most active volcano. Then we'll visit the country's southern island with John Youngson, to find out how New Zealand’s longest fault-line contributes to the gold industry. Finally in Japan, viewers will hike up to Mount Fuji – the iconic peak where science and legend converge, getting up-close and personal with a fault-line witnessing firsthand what it’s like to discover new ways of monitoring, and hopefully one day predicting, seismic activity onboard the world’s most advanced drilling vessels.
