Minerva B is a small rocky planet just like earth, where spacecraft Artemis has found water, organic molecules, and complex creatures. Is there something more to find?
'I am the mind of the spaceship, alone among the stars. 50 years ago, from a planet far away, the planet you call home, I launched. A journey of 28 trillion miles across the yawning time of space to the exoplanet, Minerva B: a small, rocky planet, much like Earth, but orbiting another sun. Here, I have found water, organic molecules, and microorganisms. When the news of my discovery reaches Earth years from now, some of you will be amazed. But others will remain unsatisfied, and you will ask, have I not found animals or birds? Have I not met intelligent life like us? And so, my search continues. I will find life of marvellous complexity, and the traces of a devastating loss.'

All cooking is transformation, and in that sense, it's miraculous, it's alchemy. But of all the different transformations we call cooking, fermentation is the most miraculous and the most mysterious. And that's because it doesn't involve any applied heat at all. Discover how microbes help turn raw ingredients into delicacies like chocolate and cheese as Pollan tackles the mysterious process of fermentation.

In just over 100 days, a new coronavirus has taken an unprepared world by storm, infiltrating every corner of the globe, sending entire nations into lockdown, killing thousands and infecting countless more. Across the world, governments are scrambling to react, hospitals are struggling to cope and an increasingly anxious public are starting to panic.
The world's media is awash with data, information and misinformation. But what are the facts? What is COVID-19 and why is this strain of coronavirus so dangerous? What happens in our bodies when the virus attacks? How does this compare to previous pandemics? What do all the the numbers really mean, and how can data modelling help us look for an exit strategy? This programme investigates the scientific facts and figures behind the biggest public health crisis in living memory, and explores the latest research from the frontline of the medical and scientific fightback.

Dr Chris van Tulleken, Dr Hannah Fry and Michael Mosley examine the latest research and explore some of the big questions about Covid-19 and the pandemic it has created. Michael visits the UK government's high-security laboratory Porton Down, where vaccines are being tested. He also uncovers what the experience of the 2002 SARs epidemic reveals about this one. Both were caused by coronaviruses, but certain key changes to today's virus have allowed it to infect the world, where SARs was contained.

A variety of cosmic events have both helpful and harmful effects on life on Earth. From the beauty of the Aurora Borealis and rainbows to the dangers of UV radiation and cosmic rays, from the miracle of photosynthesis to the thrill of a meteor shower, this episode explores how the effects generated by the sun and other extra-solar sources can literally get under our skin, scramble our technology, make life possible and threaten our existence all at the same time

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.
