Drill down to discover the treasures beneath our feet that power our world. Fossil fuels–coal, oil, and natural gas–powered the industrial revolution and allowed us to build a way of life that many cherish today. Personal cars, planes, lights, hot showers–all of these are gifts from our fossil fuels… but they have a dirty dark side in that they are polluting the planet. What is it about these natural resources that have allowed them to fuel our civilization? What secrets are locked in their molecules? Where did that energy come from, and can we find alternative energy resources that come in a cleaner form? The hunt is on for new treasures that might allow us to power our modern way of life without damaging the environment. Join NOVA as we explore the resources that both power and pollute, from modern-day oil prospecting in California, to a mega-city utility company struggling to keep the lights on during hot summer days, to China where an engineer strives to solve one of the greatest obstacles to the success of solar power. Travel the globe to see how our energy treasures are changing—and if they can keep the lights on.

Account of the ill-fated Canadian Arctic Expedition of 1913 when a group of scientists were sent to the Arctic to look for a new continent on the eve of WWI, an astonishing story of disaster and perseverance. On board were 10 scientists, 13 crewmembers, four Inuit hunters, one seamstress, her two children, and one passenger. Of these, 11 never returned and most were not heard from again until September 1914.

In May 2018, Kilauea volcano erupted, obliterating neighborhoods with devastating force and uprooting thousands of local residents. It is Hawaii's most destructive volcanic eruption in generations. How can one of the most beautiful places on Earth suddenly transform into a roaring inferno, sputtering molten lava and bombs of volcanic rock the size of refrigerators? On the ground in the early days of the eruption, NOVA joins scientists and residents alike on a breathtaking journey to investigate Kilauea's recent spike in activity. Along the way, some of Hawaii's biggest secrets are revealed: Why did these geologically distinctive volcanoes form in the middle of the Pacific? How did life establish itself on the remote islands? What does this tell us about the future of Hawaii? And what dangers yet lurk for the inhabitants of the island paradise?

Chile's Atacama Desert is the driest, oldest and deadest desert on earth. Yet it's plays host to living creatures and penguins even thrive nearby. It may provide clues to where to look for life on other, seemingly barren, planets.
