Across the universe, galaxies are going dark, and scientists don't know why the stars are losing their shine. Something is slowly drawing the curtains closed on the universe. Our milky way is under threat. Astronomers race against time to uncover the truth behind how galaxies are born and how they die before all of the lights go out.

Rainforests face more threats than ever before, but remain the last stronghold for some truly astonishing animal families. Today we know rainforests are some of the most wondrous and important habitats on Earth. It is the richest habitat on earth, teeming with millions of dramatic plants and animals. From giant landscape gardeners to a whole family supported by a single leaf, there are surprises at every turn.

This remarkable science-history series investigates the blistering pace of human endeavour in space exploration, computing, energy, resources, Earth science and our understanding of the evolution of life itself. Across the last 50 years, humans have set a blistering pace and scientific discovery. We've crossed the boundaries of our solar system, made machines that can learn harnessed the power of the sun and built life from scratch. It's a period like no other in history, where human endeavour is changing everything: this is The Great Acceleration. As we race toward the future, we must examine the journey.
In the first episode, Dr Shalin Naik explores the ambitious space shuttle mission that began in the '70s plus the future colonization of Mars. Over the past 50 years, space has become central to everything, from communications to entertainment to climate modelling. And as private enterprise enters space exploration, our understanding of the universe will only continue to expand. We will know if we can survive on other objects - the moon, maybe Mars, maybe even some of the moons of Jupiter and Saturn. Deep space is the last and infinite frontier. That's what we do as human beings. We explore, we learn, we make discoveries, from the moment we're born to the moment we die.

From the first transistor to deep learning networks, the rise of computing power over the last 50 years has been so phenomenal it's changed everything from the way we communicate to how our appliances interact. Fuelled by giant leaps forward in computer technology, the race is on. As the progress of machines continues to accelerate, so will the pace of change.

Over the last years, the world has experienced an energy revolution, driven by an urgent need to green the grid and save life on Earth as we know it. 50 years ago, a devastating oil crisis kicked off an energy revolution. The world set course to cut the costly habit of burning fossil fuels. With the urgent new threat of a changing climate, the drive to unleash the power of the sun, earth and wind has accelerated into a race for humanity's survival. Change is taken place but, is it happening fast enough to secure our future? Technologies are right here, right now, and they will enable the transition to 100% renewables, because winning the energy race means a win for the entire world.

Laurent Ballesta has yet again challenged himself to a new world record: spend 28 days at a depth of 100 meters to reveal the luxuriant and unknown depths of the Mediterranean.
Because people have been travelling there for thousands of years, this sea is be­lieved to be without secrets. And yet, far below its surface, lie vast unexplored territories, luxurious gardens worthy of the finest tro­pical coral reefs. These natural wonders are inaccessible to the traditional diver, in a twilight zone, between 60 and 120 m, where there’s less than 1% of sunlight. If diving at such depths is always a challenge, staying there is a fan­tasy, a utopia that becomes reality in 'The Deep Med'.
