A Winning Design clarifies what makes a mammal different from reptiles and birds. No, it isn't egg-laying: both the platypus and the echidna are egg-laying mammals; it's their ability to adapt. And it's this adaptability that becomes the crux of the remainder of the series. From the tiniest bat to the massive blue whale, all mammals share the ability to nurture their young on milk and regulate their own temperatures.

Our galaxy is one of hundreds of billions in the universe. View of universe through the Hubble telescope and go back almost all the way to the Big Bang.

This film reveals the work and wisdom of some of the most influential advertising creatives of our time -- people who've profoundly impacted our culture, yet are virtually unknown outside their industry. Exploding forth from advertising's 'creative revolution' of the 1960s, these artists and writers all brought a surprisingly rebellious spirit to their work in a business more often associated with mediocrity or manipulation: George Lois, Mary Wells, Dan Wieden, Lee Clow, Hal Riney and others featured in ART & COPY were responsible for 'Just Do It,' 'I Love NY,' 'Where's the Beef?,' 'Got Milk,' 'Think Different,' and brilliant campaigns for everything from cars to presidents. They managed to grab the attention of millions and truly move them.
Art & Copy is a powerful film about advertising and inspiration.

Carl Sagan opens the program with a description of the cosmos and the Spaceship of the Imagination. The ship journeys through the universe's hundred billion galaxies, the Local Group, the Andromeda Galaxy, the Milky Way, the Orion Nebula, our Solar System, and finally the planet Earth. Eratosthenes' successful calculation of the circumference of Earth leads to a description of the ancient Library of Alexandria. Finally, the Ages of Science are described, before pulling back to the full span of the Cosmic Calendar.

Famed astrophysicist Neil deGrasse Tyson takes a tour of the Solar System and the known universe establishing the components of Earth's "address" within the Virgo Supercluster. He then shares the story of the person who championed an expansive understanding of Earth's place in the universe by presenting Renaissance Italian Giordano Bruno's vision of the universe as a limitless expanse of space and time. He then makes an exploration into the Cosmic Calendar, which dates back to the dawn of the Big Bang (similar to the presentation from episode 1 of the original series). The episode ends with deGrasse Tyson narrating how he met his mentor Carl Sagan, who hosted the first Cosmos series.

Cosmic rays capable of destroying human DNA are hurtling through outer space like subatomic bullets, causing space crews radiation damage.
Cosmic rays are intergalactic alien interlopers on our Milky Way. But the source of their power is a mystery. Are they coming from other galaxies? Are they coming from things in between the galaxies? Where do cosmic rays come from? Truth is, the most powerful ones, we haven't got a clue. The race is on to solve the mystery of the fastest particles in the universe.
