What if in the distant realms of our galaxy there is a planet similar to ours where life can exist?
Using the latest technology and telescopes, scientists are exploring the outer reaches of our solar system, searching for life, and reexamining how they perceive life on other planets. This documentary shows us the sights and sounds of distant worlds, as astrobiologists explain how life could exist on them. With the most modern telescopes, scientists are now seeing more complex ecosystems on our neighbouring planets than they had thought to exist. Vast salt water oceans, active volcanoes and molecules that could start life are present in many of the planets. Could life be starting on other planets? Is a primitive form of life that once was the beginning of humans now possibly active on other planets? We may not be alone.
