Are we alone? SETI--the Search for Extraterrestrial Intelligence--is a privately funded project using radio telescopes and optical telescopes to scan the stars for signals.

In the third episode, Will Smith crosses the Serengeti to catch one of the greatest events of nature. "An image, one and a half million wildebeests on the plains of Africa in the most dramatic migration on Earth, has stayed with me since around thirty years ago I picked up a National Geographic Magazine and saw it. And finally, I'm here to see it."

It is the year 2546. Corporations rule the world, and an agent is on a secret mission to explore the untold stories of the past. His journey leads him into a secret virtual reality where one corporation has recreated the 1980s, an era that witnessed the birth of video game development, an event in which a politically and economically restricted small European country, Hungary, had a significant role.
He discovers a strange but exciting world, where computers were smuggled through the Iron Curtain and serious engineers started developing games. This small country was still under Soviet pressure when a group of people managed to set up one of the first game development studios in the world, and western computer stores started clearing room on their shelves for Hungarian products. These developers really didn't know it was impossible, because they created games including amazing technical feats that even engineers at Commodore thought their machines weren't capable of.

The little known story of our quest to understand the origins of the Moon. Neil Armstrong's "giant leap for mankind" began a scientific journey of discovery that lead to one of the most startling conclusions in the history of astronomy. The Moon was born from Earth.

Most planets we know of are so hellish, it seems impossible that anything could live. But it's amazing where life can take hold in the Earth. Astrobiologists look for simple single-celled microbes known as extremophiles in places as Danakil Depression, known in Ethiopia as 'The Gateway to Hell.'
In Episode 2, the fictional world is Janus, a planet in such a close orbit than its rotation is locked by the star's gravity and it always shows the same face to its sun. On one side of the planet, it's always daytime, a searing desert. On the other side, it's forever night, a frozen shadowland. Squeezed between the two, a sliver of perpetual twilight. Freezing meltwater flows from the cold side, carving canyons through the landscape. Deep in these canyons lives an extraordinary five-legged creature.

Since the original series went on the air in 1966, the Star Trek franchise has had a history of ups and downs in the toy business - from AMT's faithful scale model kit of the USS Enterprise to Remco's obscure tie-in merchandise, to Mego's best–selling action figure line. Following Mego's bankruptcy in 1983 and a string of flops by Ertl and Galoob, Playmates Toys picked up the toy license in the late 1980s and sparked a resurgence in the franchise's toy sales.
From the mid-2000s onwards, companies such as Art Asylum and McFarlane Toys continue to keep the Star Trek toy franchise alive.
