The northern lights (aurora borealis) are one of the greatest natural wonders of our world. They have dazzled people for thousands of years and intrigued scientists for centuries. What causes the kaleidoscope of colours, patterns and shapes? Why do the northern lights sometimes appear near the equator? And could knowledge of Earth’s auroras help answer questions about life on other planets? Now, the mysteries of the lights are being uncovered thanks to an international team of scientists. David Suzuki journies to the freezing conditions of the Northwest Territories, to meet the experts working on pioneering experiments that hope to answer the biggest mysteries about the lights. On this dazzling expedition, he uncovers how these celestial fireworks form and why they dance in a whole pallet of colours across the night sky. He seeks to find out why they usually are only seen in narrow bands of the sky around the North (or South) Pole, and why solar storms can make aurora appear as far south as the Caribbean. The Nature of Things is one of the most successful series in the history of Canadian television. Hosted by the world-renowned geneticist and environmentalist, David Suzuki, the program is in its 58th season, a landmark by any standard. Every week, the influential program presents stories that are driven by a scientific understanding of the world. Stories full of adventure, drama and insight. The programmes entertain and inspire audiences by engaging with the people and personalities behind the science. From the search for other life in the universe to the psychology of babies, from the furry animals that invade your backyard to the consequences of human progress, The Nature of Things throws open the door to the wonder and accomplishments of science.
