Artificial selection is one example, eyes another, of the well-documented and inescapable process of evolution--change in a population of species over time--by natural selection. These are some of the things that molecules do.

Standing Up in the Milky Way

More than three decades after the debut of Carl Sagan's ground-breaking and iconic series, "Cosmos: A Personal Voyage," it's time once again to set sail for the stars. Host and astrophysicist Neil deGrasse Tyson sets off on the Ship of the Imagination to discover Earth's Cosmic Address and its coordinates in space and time. Viewers meet Renaissance Italy's Giordano Bruno, who had an epiphany about the infinite expanse of the universe. Then, Tyson walks across the Cosmic Calendar, on which all of time has been compressed into a year-at-a-glance calendar, from the Big Bang to the moment humans first make their appearance on the planet.

When Knowledge Conquered Fear

Neil deGrasse Tyson sets off on the Ship of the Imagination to chase a single comet through its million-year plunge toward Sol. Later, Tyson visits the birth-place of Sir Isaac Newton and retraces the unlikely friendship between Newton and brilliant polymath Edmond Halley. It was Halley's patience and generosity which allowed Newton to conquer his fear of isolation and find the courage to publish his masterwork, "Principia Mathematica" which launched a scientific revolution.

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.

Webb Telescope: The Story So Far

In July 2022, the James Webb Space Telescope released its first images. They were visually stunning, and it was clear they provided more detail of stars, galaxies and planets than ever before. But for the scientists waiting on the data, this was just the beginning of their journey to discover what the new telescope would reveal. Since then, they have been working hard and publishing papers on all the data JWST has been sending back. Two years ago, just after the first images were released, Chris Lintott set off on a road trip to meet some of the scientists that were excitedly waiting on the first data. He wanted to find out what they hoped it could reveal. To mark the second anniversary Chris, along with fellow presenters Maggie Aderin-Pocock and George Dransfield, headed off to meet scientists old and new, to find out what the Webb Telescope has told us so far. Chris gives us a run-down of the highs and lows the Webb Telescope has been through and the other discoveries it has made. Maggie is off to Bristol University to revisit Dr Hannah Wakeford who has been using JWST data to reveal what interesting chemicals exoplanet atmospheres contain. George meets Professor Leigh Fletcher at the University of Leicester. When Chris met him two years ago, only one JWST image of Jupiter had been released. Now, he has data from all four of the outer planets of the solar system, and they have all thrown up surprises. JWST has revealed new jet streams on Jupiter and provided a greater understanding of its Galilean moons. Seasonal changes on Saturn have now been documented, and Uranus and Neptune have thrown up quirks that need another few years of work to understand. Chris also visits the University of Cambridge to meet Dr Sandro Tacchella, who has been part of a team looking back at some of the earliest galaxies. He explains what new light the JWST data can shed on ancient stars, and what that can reveal about how our cosmos formed after the Big Bang. Finally, our resident astronomer Pete Lawrence guides us through what there is to see in this month’s night sky, and how you too can look at some of the same targets as the James Webb Space Telescope – just not quite in the same level of detail!

Swallowed by a Black Hole

In summer 2013, the black hole at the centre of the Milky Way was getting ready to feast. A gas cloud three times the size of our planet strayed within the gravitational reach of our nearest supermassive black hole. Across the globe, telescopes were being trained on the heart of our galaxy, some 27,000 light years from Earth, in the expectation of observing this unique cosmic spectacle. For cosmic detectives across the Earth, it was a unique opportunity. For the first time in the history of science, they hoped to observe in action the awesome spectacle of a feeding supermassive black hole.
