Episodes
A Spacetime Odyssey
Standing Up in the Milky Way
The Ship of the Imagination, unfettered by ordinary limits on speed and size, drawn by the music of cosmic harmonies, can take us anywhere in space and time. It has been idling for more than three decades, and yet it has never been overtaken. Its global legacy remains vibrant. Now, it's time once again to set sail for the stars.
Some of the Things that Molecules Do
Host Neil deGrasse Tyson is on a voyage to explore the relatedness of all living things and the possible evolution of life in the cosmos. Go on a journey to discover how artificial selection turned the wolf into canine breeds and how natural selection sculpted the complex human eye. Later, Tyson visits the grand Hall of Extinction, a monument to all the broken branches on the tree of life. Retrace the story of life on Earth and the unbroken thread that stretches from the first one-celled organisms to human life.
When Knowledge Conquered Fear
There was a time, not so long ago, when natural events could only be understood as gestures of divine displeasure. We will witness the moment that all changed; but first, the Ship of the Imagination is in the brooding, frigid realm of the Oort Cloud, where a trillion comets wait. Our Ship takes us on a hair-raising ride, chasing a single comet through its million-year plunge towards the Sun.
A Sky Full of Ghosts
An exploration of how light, time and gravity combine to distort our perceptions of the universe. We eavesdrop on a series of walks along a beach on summer nights in the year 1809. William Herschel, whose many discoveries include the insight that telescopes are time machines, tells bedtime stories to his young son, John, who will grow up to make some rather profound discoveries of his own.
Hiding in the Light
The Ship of the Imagination travels back in time to reveal 11th century Europe and North Africa during the golden age of Islam, when brilliant physicist Ibn al-Haytham discovered the scientific method and first understood how we see, and how light travels. Later, William Herschel discovers the infrared and the signature hidden in the light of every star, eventually unlocking one of the keys to the cosmos.
Deeper, Deeper, Deeper Still
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.
The Clean Room
To determine the true age of the Earth, geochemist Clair Patterson developed the uranium-lead dating method to make an unprecedented discovery – calculating Earth's age of 4.5 billion years. But Patterson's groundbreaking discoveries were just beginning. Patterson made it his mission to draw public attention to the detrimental effects of lead in the environment and dedicated his career to fighting against the petroleum and chemical industry, eventually achieving public health's biggest victory of the 20th century.
Sisters of the Sun
Discover the remarkable story of Annie Jump Cannon and Cecilia Payne, two incredible women who challenged conventional wisdom and uncovered the real-life story of the stars. Cannon led a group of female astronomers in the early 20th century to catalogue the spectral characters of stars, and two decades later, young British beauty Payne joined forces with Cannon to analyze the data and uncover the chemical compositions of the stars. Later, travel on the Ship of the Imagination to explore the lives and deaths of stars.
