1. METEOR STRIKE 

Scientists hunt for debris from the 7,000-ton asteroid that crashed in Russia, searching for clues to its origin and makeup; a review of past explosions, from Tunguska to the asteroid that extinguished the dinosaurs 65 million years ago.

2. FINDING LIFE BEYOND EARTH Part 1: ARE WE ALONE? 

Scientists are on the verge of answering one of the greatest questions in history: Are we alone? Finding Life Beyond Earth immerses audiences in the sights and sounds of alien worlds, while top astrobiologists explain how these places are changing how we think about the potential for life in our solar system. We used to think our neighboring planets and moons were fairly boring—mostly cold, dead rocks where life could never take hold. Today, however, the solar system looks wilder than we ever imagined. Powerful telescopes and unmanned space missions have revealed a wide range of dynamic environments—atmospheres thick with organic molecules, active volcanoes, and vast saltwater oceans. This ongoing revolution is forcing scientists to expand their ideas about what kinds of worlds could support life.

1. COLLIDING CONTINENTS 

The history and a projection of the future of the Earth's land masses caused by continental drift is explained by the theory of plate tectonics.

2. How Earth Made Us | How the Earth Changed History

Professor Iain Stewart examines the role of geology in the history of mankind in this documentary program. Each of the classical elements plays a role - for instance, he points out that mankind has been drawn to fault lines for centuries, since this is the best place to find minerals, oil, soil suitable for farming, etc. But with these riches comes great danger, of course, since locating communities on the fault lines makes them vulnerable to earthquakes. Subsequent episodes review the cycle of freshwater, the force of the wind, and fire both as a source of energy and a terrifying force of nature. From crystal caves in Mexico to holes in the Iranian desert and a mysterious lake in Oregon, Stewart travels the globe to hammer his point home.

A look at how climate change affects our environment and what society can do to prevent the demise of endangered species, ecosystems and native communities across the planet.

Using his celebrity status to draw attention to the problem of global warming, one of the most important and pressing issues of our time, actor and United Nations Messenger of Peace, Leonardo DiCaprio, travels the globe to witness firsthand the effects of an impending environmental disaster. By visiting ancient melting glaciers and leveled Indonesian tropical forests, DiCaprio unearths an urgent situation and the world's dependence on fossil fuels, going as far as to visit President Obama himself for an in-depth interview. But, can this crusade inspire the climate-change deniers?

1. OUR ATMOSPHERE

In the empty blackness of space, surrounded by hostile planets and freezing vacuum, planet Earth is an oasis of life. And all because of our protective cocoon of gas. This blanket of air shapes everything we see on Earth. It protects, insulates, and sustains us. It carries water around the globe and shields us from cosmic impacts and killer radiation. It’s time to uncover the invisible wonder that is our atmosphere.

1. SECRETS OF THE PSYCHICS

Can psychics predict the future? Many people seem to think so. Others argue that, in most cases, so-called psychic experiences are really misinterpretations of events. In this episode of NOVA, magician and confirmed skeptic James Randi challenges viewers to weigh the evidence for and against the existence of psychic phenomena.
