This episodes the nature of the cosmos on the micro and atomic scales, using the Ship of the Imagination to explore these realms. Tyson describes some of the micro-organism that live within a dew drop, demonstrating parameciums and tardigrades. He proceeds to discuss how plants use photosynthesis via their chloroplasts to convert sunlight into chemical reactions that convert carbon dioxide and water into oxygen and energy-rich sugars. Tyson then discusses the nature of molecules and atoms and how they relate to the evolution of species. He uses the example set forth by Charles Darwin postulating the existence of the long-tongued Morgan's sphinx moth based on the nature of the comet orchid with pollen far within the flower. He further demonstrates that scents from flowers are used to trigger olfactory centers in the brain, stimulating the mind to threats as to aid in the survival of the species. Tyson narrates how Greek philosophers Thales and Democritus postulated that all matter was made up of combinations of atoms in a large number of configurations, and describes how carbon forms the basic building block for life on earth due to its unique chemical nature. Tyson explains on the basic atomic structure of protons, neutrons, and electrons, and the nature of nuclear fusion that occurs in most stars. He then discusses the existence of neutrinos that are created by these nuclear processes in stars, and that detecting such sub-atomic particles which normally pass through matter require subterranean facilities like the Super-Kamiokande that were used to detect neutrinos from the supernova SN 1987A in the Large Magellanic Cloud before light from the explosion were observed due to their ability to pass through matter of the dying sun. Tyson compares how neutrinos were postulated by Wolfgang Pauli to account for the conservation of energy from nuclear reactions in the same manner as Darwin's postulate on the long-tongued moth. Tyson concludes by noting that there are neutrinos from the Big Bang still existing in the universe but due to the nature of light, there is a "wall of infinity" that cannot be observed beyond.

NASA’s next era will be its greatest yet. That is the clear 'roadmap' painted by Journey To Space. The film absolutely annihilates the perception that the space program died with the end of the Space Shuttle Program by showcasing the exciting plans NASA and the space community are working on, and the challenges they must overcome to carry out audacious missions such as landing astronauts on Mars and capturing asteroids. In the past half century, humans have punched through the stratosphere, walked on the moon, and lived continuously in orbit. In the coming decades, our unquenchable curiosity will take our species beyond the cradle of Earth to touch the face of another world. Strap in for the next giant leap. Next stop ... Mars!

The second episode takes a look at how humans have always been voyagers and explorers, leaving the comfort of native shores to explore. Neil DeGrasse Tyson will show us a long-term vision of humanity's future worlds.

(click CC for subtitles) 'a-ha' is Norway's only international pop band and their hit 'Take On Me' is still one of the most-played songs of the last millennium. The film follows the band over a period of four years, telling the full story of how three young men followed their impossible dream of becoming Norwegian pop stars. When 'Take On Me' reached number 1 on Billboard in the US in 1985, the dream came true. Or did it?
Almost 35 years after their breakthrough, a-ha still creates magic on stage with their melancholic and timeless music. They tour the world but drive in separate cars and stay in separate hotel rooms. They only meet on stage, doing the one thing they love. The film closely portrays the challenging creative and personal dynamics of a group of three strong individuals who have grown up together, but in different directions. What does success do to friendship? Why are they not capable of creating new music together anymore? This is a story of great music, big ambitions, broken friendship--and maybe forgiveness.

Why do we sleep? And what does sleep have to do with memory, trauma, and our emotions? From fruit flies to whales, virtually every animal sleeps. But why? Why do we need to spend nearly a third of our lives in such a defenseless state? Scientists are peering more deeply into the sleeping brain than ever before, discovering just how powerful sleep can be, playing a role in everything from memory retention and emotional regulation to removing waste from our brains. So why are we getting so little of it?
