The Search For Life in Space (2016)

To determine whether we're alone in the universe, astrobiologists look to Jupiter, Mars and, closer to home, extreme environments on Earth.

If we are to believe what we see in movies and on television, the universe is populated with other worlds and civilizations that rival our own.

The search for life is one of the most active fields in space science and involves a wide variety of scientific disciplines, including planetary science, astronomy and astrophysics, chemistry, biology, chemistry, and geoscience.

The oceans define the earth. They are crucial to life and we used to think that they were unique to our blue planet. But we were wrong. It has recently been discovered that there are oceans all over our solar system, and they are very similar to our own. And now scientists are going on an epic journey in search of new life in places that never seemed possible. Nasa is even planning to dive to the depths of a strange, distant ocean in a remarkable submarine. Horizon discovers that the hunt for oceans in space is marking the dawn of a new era in the search for alien life.

An exploration into our planetary past and a search for humanity's place in the future. With narration by Cate Blanchett.
