Between the blue sky above us and the infinite blackness of space lies a frontier full of enigmas that scientists have only just begun to investigate. “At the Edge of Space” takes viewers on a spectacular exploration to probe the earth-space boundary zone, 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.

Every year, 100 million Monarch butterflies set off on an incredible journey across North America. These beautiful creatures fly 2,000 miles to reach their remote destination: a tiny area high in the mountains of Mexico. Yet scientists are still puzzling over how the butterflies achieve this tremendous feat of endurance — and how, year after year, the Monarchs navigate with such hair's-breadth precision.
We have certainly had a lot of cold weather, ice and snow in Virginia lately. And I am sure you have been feeling the cold right through to your bones some nights. But, have you ever considered what happens to the Wood Frog who lives in the Northern United States and Canada?
The Shannon is Ireland’s greatest geographical landmark and longest river. It is both a barrier and highway — a silver ribbon holding back the rugged landscapes of the west from the gentler plains to the east. On its journey south, the Shannon passes through a huge palette of rural landscapes, where on little-known backwaters, Ireland’s wild animals and plants still thrive as almost nowhere else.
This is the intimate and revealing story of Stephen Hawking’s life. Told for the first time in Hawking’s own words and with unique access to his home and public life, this is a personal journey through Hawking’s world. The audience joins him at home, under the care of his nursing team; in San Jose as he “wows” a packed theatre audience; in Silicon Valley as he meets a team of technicians who hope to speed up his communication system; and as he throws a party for family and friends.
The coywolf, a mixture of western coyote and eastern wolf, is a remarkable new hybrid carnivore that is taking over territories once roamed by wolves and slipping unnoticed into our cities. Its appearance is very recent — within the last 90 years — in evolutionary terms, a blip in time. Beginning in Canada but by no means ending there, the story of how it came to be is an extraordinary tale of how quickly adaptation and evolution can occur, especially when humans interfere.
From coast to coast, some 30 million white-tailed deer make their home in the United States. Deer are the most highly studied mammals in the world, but does the typical homeowner with deer in the yard know how long deer can live? When they sleep? How many babies a doe can have each year?
Enter the hidden world of white-tailed deer outfitted with night-vision cameras and GPS tracking equipment to see them not as common backyard creatures, but as intelligent, affectionate family members.
NASA’s planet-hunting Kepler Telescope has discovered thousands of exotic new worlds far beyond our solar system. Are any of them like Earth? And what sort of life could flourish on them?
With vivid animation and input from expert astrophysicists and astrobiologists, NOVA takes you on a mind-bending exploration of these strange worlds and the possible creatures we might one day encounter there.
In the early 20th century, the average American medicine cabinet was a would-be poisoner’s treasure chest: radioactive radium in health tonics, thallium in depilatory creams, morphine in teething medicine and potassium cyanide in cleaning supplies. While the tools of the murderer’s trade multiplied as the pace of industrial innovation increased, the scientific knowledge (and political will) to detect and prevent the crimes lagged behind. Unnatural deaths were handled by the coroner, a position handed out to the corrupt and unqualified as political payback.
