NatureCold Warriors: Wolves And Buffalo” at 7 pm
For thousands of years, wolves hunted buffalo across the vast North American plains until the westward settlement of the continent saw the virtual extinction of these vast herds and their eternal predators, the wolves. However, this ancient relationship was not lost altogether and continues uninterrupted in just one location — on the northern edge of the continent’s central plains in a place named Wood Buffalo National Park. Today the ancestors of those ancient buffalo and wolves still engage in epic life and death dramas across this northern land. Packs of wolves up to 30 strong hunt the largest land mammals on the continent — buffalo. By getting to know a specific pack of wolves and the individuals that make up the pack, we get a sense of how these two animal species (wolves and buffalo) live together in what seems like a forgotten corner of the world.

NOVA Earth From Space” at 8 pm
This film reveals a spectacular new space-based vision of our planet. Produced in extensive consultation with NASA scientists, NOVA takes data from earth-observing satellites and transforms it into dazzling visual sequences, each one exposing the intricate web of forces that sustains life on earth. Viewers witness how dust blown from the Sahara fertilizes the Amazon; how a vast submarine “waterfall” off Antarctica helps drive ocean currents around the world; and how the sun’s heating up of the southern Atlantic gives birth to a colossally powerful hurricane. From the microscopic world of water molecules vaporizing over the ocean to the magnetic field that is bigger than Earth itself, this show reveals the astonishing beauty and complexity of our dynamic planet.
