The constellation of the Pleiades provides a vehicle for us to explore a series of paradoxes and epochal discoveries for humanity. The untold story of the modern "sisters of the sun," the early 20th century female astronomers, led by two deaf women, at Harvard who catalogued the stars. It's also the story of the young British woman who joined forces with them, her defiance of the world's leading expert, and how she taught the world what the stars are really made of.

A constellation is a group of stars that are connected together to form a figure or picture. Explore some of the 88 official constellations and learn about some of the highlights of each.

Beginning with the separation of the fuzzy thinking and pious fraud of astrology from the careful observations of astronomy, Sagan follows the development of astronomical observation. Beginning with constellations and ceremonial calendars (such as those of the Anasazi), the story moves to the debate between Earth and Sun-centered models: Ptolemy and the geocentric worldview, Copernicus' theory, the data-gathering of Tycho Brahe, and the achievements of Johannes Kepler (Kepler's laws of planetary motion and the first science-fiction novel).

Ideas about time and space are explored in the changes that constellations undergo over time, the redshift and blue shift measured in interstellar objects, time dilation in Albert Einstein's theory of relativity, the designs of both Leonardo da Vinci and spacecraft that could travel near light speed, time travel and its hypothetical effects on human history, the origins of the Solar System, the history of life, and the immensity of space. In Cosmos Update, the idea of faster-than-light travel by wormholes (researched by Kip Thorne and shown in Sagan’s novel Contact) is discussed.

In August 1977, the Big Ear Radio-telescope in Ohio received a strange signal from the Sagittarius constellation while searching for intelligent extra-terrestrial life. It had a duration of 72 seconds and an intensity 30 times higher than usual. Named the Wow signal, it is still being considered as one of the best examples of having being sent by intelligent extraterrestrial life. But, nothing has revolutionised the search of extra-terrestrial intelligent life as much as the recent discovery by the Kepler Satellite, of thousands of Earth-like planets where life could be possible. Join the debate with this stunning documentary, as we ask Is Anybody Out There?

Dylan Jones is in the driving seat for this authoritative four-part look back. No stone remains unturned, as he revisits the New Romantics, rap, modern dance music, hip-hop, indie jingle, synth-pop, house music and club culture. He makes the case that the 1980s was the most radical, innovative and creative decade in the history of pop because, unlike other decades, unleashed a myriad of new musical genres in just 10 years.
In the first part, Dylan Jones explores how in this decade the world-conquering genres of rap, hip-hop and modern dance music were launched, while guitar-driven indie flourished in a constellation of scenes spread out across the world. And a technological revolution was changing how music was made, filling the charts with a starburst of innovative records. Meanwhile, the launch of MTV turned pop into a visual medium, allowing artists as varied as U2 and Eurythmics to take charge of how they presented themselves. Featuring interviews with Nile Rodgers, Bananarama, Primal Scream's Bobby Gillespie, Mark Ronson, Trevor Horn and Soul II Soul's Jazzie B.
