Astronaut Chris Hadfield reveals the unlikely and unexpectedly interconnected systems that allow life on our planet to breathe.
After 665 weightless days in space, NASA's most experienced astronaut, Peggy Whitson, smashes through the atmosphere on her last journey home to planet Earth. With unprecedented filming on board the ISS during Peggy's final mission and with the support of our other featured astronauts, we reveal how their time in space transforms their understanding of our planet's wonders, insights that will change our perspective, too. There is no place like home. Or is there? Just how strange is our rock, and is it really unique in the universe? Astronaut host – Peggy Whitson.

The Ship of the Imagination ventures on an epic voyage to the bottom of a dewdrop to explore the universe on the smallest scale and observe exotic life forms invisible to the naked eye. Then, host Neil deGrasse Tyson explains the neural network in our brains which determine our sense of smell and memory, and later, he travels deep beneath the surface of the Earth to discover the most mysterious particle we know.

Questions are raised about the search for intelligent life beyond the Earth, with UFOs and other close encounters refuted in favor of communications through SETI and radio telescope such as the Arecibo Observatory. The probability of technically advanced civilizations existing elsewhere in the Milky Way is interpreted using the Drake equation and a future hypothetical Encyclopedia Galactica is discussed as a repository of information about other worlds in the galaxy. The Cosmos Update notes that there have been fewer sightings of UFOs and more stories of abductions, while mentioning the META scanning the skies for signals.

New planets are now being discovered outside our solar system on a regular basis, and these strange new worlds are forcing scientists to rewrite the history of our own solar system. Far from a simple story of stable orbits, the creation of our solar system is a tale of hellfire, chaos and planetary pinball. It's a miracle our Earth is here at all.
It's not enough for Earth to be habitable; it also has to be lethal for life to thrive. This is the story of how life evolved hand in hand with death. Astronaut host – Jerry Linenger
