The computer animated drama takes place on Darwin IV, a planet 6.5 light years from earth, with 2 suns and 60% of Earth's gravity. Earth sends a pilot mission with three probes. This robotic fleet is responsible for finding and assessing any life forms on Darwin IV. The probes soon find themselves in the middle of a developed ecosystem teeming with diversity of life of all sizes. "Alien Planet" is motivated by real science missions, such as the NASA Origins Program and the NASA / JPL Planet-Finder Mission, as well as the European Space Agency's Darwin Project. It is a cosmic expedition along side Stephen Hawking, Michio Kaku, Jack Horner, Craig Venter, and George Lucas, and NASA's Chief Scientist Jim Garvin. No longer just the domain of science fiction, "Alien Planet" dramatizes an exciting and possible answer to what alien life really looks like and when we'll find it.

Our universe reveals itself in ways we’ve never seen before, thanks to new discoveries in astrobiology. Today, the advent of cutting-edge observational instruments is shedding light on amazing facts about life and the universe. NASA's next-generation space telescope TESS (Exoplanet Survey Satellite) has begun its search for Earth-like planets belonging to other star systems. How many of these 'exoplanets' can host life, and what kind of life forms can evolve in these environments?

It's a golden age for planet hunters: recently, they've discovered more than 750 planets orbiting stars beyond our sun. Some of them, like a planet called Kepler-22b, might even be able to harbor life. What would that life look like? Combining startling animation with input from expert astrobiologists, Alien Planets Revealed takes viewers on a journey of the imagination as we 'build' aliens from the ground up. What chemical building blocks will make up their genetic code? How will life get started and how will the exotic environment on a planet like Kepler-22b drive evolution? Bringing the creative power of veteran animators together with the latest discoveries in astrobiology, Alien Planets Revealed provides a glimpse of the creatures we might one day encounter beyond our solar system.

Is there anyone out there? Astronomers have been pointing their radio telescopes at the skies for decades trying to pick up alien signals, so far without success. But now there's a new way of looking for aliens. Hitch a ride with Dr Graham Philips as he joins astronomers trawling through the galaxy looking for signs of extra-terrestrial intelligence.

We are the generation of human beings that are going to know whether or not we're alone in the universe. This episode explores the search of exoplanets, from ancient Greek philosophers to the discoveries made possible with the Kepler Telescope. Unbelievable new worlds, planets made of diamond, planets of raining glass, worlds in collision, some plunging into stars, and others that just might harbor life.
Thanks to today's planet hunters, our views of the universe and of our place in it are undergoing one of the greatest revolutions in scientific history.

Humans have long gazed up at the night sky, wondering whether other lifeforms and intelligences could be thriving on worlds far beyond our own. But over the last few decades, ultra-sensitive telescopes and dogged detective work have transformed alien planet-hunting from science fiction into hard fact. We expected to find worlds similar to the planets in our own solar system, but we instead discovered a riot of exotic worlds. Vivid animation based on data from the most successful planet hunter of them all, the Kepler space telescope, brings these worlds into view: puffy planets with the density of polystyrene, unstable worlds orbiting two suns and 1,000-degree, broiling gas giants with skies whipped into titanic winds.
But perhaps the most startling discovery was the number of worlds that may be contenders for a second Earth, at the right distance from their sun to have that ingredient so crucial for life as we know it, liquid water. Amongst them, we witness the most tantalizing discovery of all: a so-called ‘super-Earth’, situated in the Goldilocks zone - the area just the right distance from a sun to potentially support life - and with the faint signal of water in its atmosphere.
