Episode 08: SISTERS OF THE SUN The Pleiades Constellation – a guide for our ancient forebears. They looked into the night sky and used the Pleiades to invent agriculture. Their improved lot moved them from a people living under the heavens to a people living in dwellings, now disconnected from the stars above them. Fables and traditions – from Halloween to the native American Kiowa nation’s myth of the Devil’s Tower – they all originated from the Pleiades. The ancient Greeks saw the constellation Orion chasing the Seven Sisters across the night sky. Legends ascribed by human storytellers to give meaning to these distant mysterious points of light. We hear a new story; that of two 20th century female astronomers at Harvard who counted the stars. A young British lady joined them in their efforts, resisting the world’s leading authority, and she taught the world about the real nature of the stars in our sky. Our Ship of the Imagination takes us on an exploration through stellar lifecycles including our own familiar Sun. Looking up through The Window on the Future we travel to Earth and live through the final ideal day on our mother planet. Exploring farther we stand witness to the tragic death of a binary star system. In Australia we view the heavens with clarity akin to our ancestors’ experiences. 7,500 light years away we see Eta Carina and its malevolent companion, torturing it with its strong gravity. Torn and twisted not to become a supernova, but one day to light up our skies as a hypernovae. Neil samples the delights of a Tuscan vineyard showing how sunshine becomes moonshine. As we end this chapter of our travels, he guides us to the planet of a humdrum star orbiting a globular cluster. We see the most beautiful sight never seen until now; not a sunrise but a galaxy rise, as morning is brilliantly transformed not by one sun but two hundred billion suns! This is the rising of our Milky Way. “Writing is perhaps the greatest of human inventions, binding together people, citizens of distant epochs, who never knew one another. Books break the shackles of time.” – Carl Sagan, “Cosmos” Episode 09: THE ELECTRIC BOY Our 21st century world of hi-tech, satnavs, Twitter and Facebook, communication with our robotic ambassadors at the fringes of our solar system – these all are owed to the remarkable genius of Albert Einstein. We start with Isaac Newton’s problem of why an apple falls. Could this be the same riddle of why the planets are pulled towards the Sun as if on an invisible tether? We move through Einstein’s early childhood and see how his father sparked Albert’s creative genius with the gift of a compass. How can the needle move if there is nothing but empty space behind it? There must be a deeply hidden reason to this. We meet young Michael Faraday; born into obscure poverty he rose above his humble beginnings to invent the motor and the generator. He is our bridge from the old world to our world of high tech iPhones and computer tablets. Caught in th
