Our Universe part 1

   2022    Nature    HD
Narrated by Morgan Freeman, this ambitious documentary series unfolds the extraordinary story of the universe across millions of years, weaving together its deep connection to life on Earth. In the first part of the series, we offer the first three episodes, beginning with an intense exploration of the sun as a life-giving force, following one cheetah’s hunt for survival across the vast plains of the Serengeti. From there, we witness the steady pulse of the universe through the eyes of a chimpanzee, tracing life’s path from birth to a final moment of calm. Finally, we immerse ourselves in the challenging year of an Alaskan brown bear as it endures the harsh winter, emerging into the warmth and renewal of summer. Each scene offers a breathtaking glimpse into the delicate and awe-inspiring rhythms of life, nature, and the cosmos.

Our Universe part 2

   2022    Nature    HD
In the captivating second part of “Our Universe”, chapters 4 to 6 are presented together in an unmissable journey through the cosmos and life on Earth. These episodes delve deep into the elements that formed our world, the essential role of water, and the unseen forces that shape our lives. They offer an enthralling exploration of our place in the Universe. Dive in to experience this profound story of existence, from stardust to soulmates.
In the fourth chapter, we uncover how the elements essential to life were forged in the hearts of stars. Following a green sea turtle’s quest across the ocean for these elements, this episode reminds us that life is built from the remnants of ancient stars. The fifth chapter takes us back to the miraculous arrival of water on Earth, exploring how this vital substance transformed a barren landscape into a thriving blue planet. In the final chapter we witness gravity’s grand influence on life, following two king penguins as their journey of attraction and survival unfolds against the cosmic force that binds us all.

Humans

   2021    Nature
A new force threatens our perfect planet. In the past, five mass extinction events were caused by cataclysmic volcanic eruptions. It was not the lava or ash that wiped out life, but an invisible gas released by volcanoes: carbon dioxide. Almost every part of modern life depends on energy created by burning fossil fuels, and this produces CO2 in huge amounts. Humans are changing our planet so rapidly, it’s affecting earth’s life support systems: our weather, our oceans and the living world. The greatest change to be made is in how we create energy, and the planet is brimming with natural power that can help us do just that. It’s these forces of nature - the wind, the sun, waves and geothermal energy - that hold the key to our future.
Through compelling animal-led stories and expert interviews, we discover how CO2 is destabilising our planet. We meet rescued orphaned elephants in Kenya, victims of ever worsening droughts, and join ocean patrols off the coast of Gabon fighting to save endangered sharks. In the Amazon, we witness wildlife teams saving animals in the shrinking forests, and in San Diego we enter a cryogenic zoo preserving the DNA of endangered species before they become extinct.

Journey to a Black Hole

   2021    Science
We as humans often question the creation of the universe. How was the universe created? How does it work? This series uses global experts from organizations like NASA and CERN to help us understand how this works, and uses CGI to demonstrate the phenomena.
Episode 1 starts the new season as we dive deep into the black holes. The galaxy M87 is known for having at the core a super massive black hole. This black hole is the first ever photographed and we will witness the experts trying to find out the secrets of this famous black hole. In the meantime, they have overcome the scorching winds and death ray jets. And of all its hurdles, the event horizon will be the most difficult. This place is known for its uniqueness of time and space, where time stays still while the laws of physics fail.

Alien Worlds: The Search for Second Earth

   2021    Science
Humans have long gazed up at the night sky, wondering whether other lifeforms and intelligences could be thriving on worlds far beyond our own. But over the last few decades, ultra-sensitive telescopes and dogged detective work have transformed alien planet-hunting from science fiction into hard fact. We expected to find worlds similar to the planets in our own solar system, but we instead discovered a riot of exotic worlds. Vivid animation based on data from the most successful planet hunter of them all, the Kepler space telescope, brings these worlds into view: puffy planets with the density of polystyrene, unstable worlds orbiting two suns and 1,000-degree, broiling gas giants with skies whipped into titanic winds.
But perhaps the most startling discovery was the number of worlds that may be contenders for a second Earth, at the right distance from their sun to have that ingredient so crucial for life as we know it, liquid water. Amongst them, we witness the most tantalizing discovery of all: a so-called ‘super-Earth’, situated in the Goldilocks zone - the area just the right distance from a sun to potentially support life - and with the faint signal of water in its atmosphere.

Black Holes: Heart of Darkness

   2021    Science
The centre of our galaxy is home to an invisible monster of unimaginable power – a supermassive black hole named Sagittarius A star, with four million times the mass of the Sun. Recent astronomical breakthroughs have confirmed not only that black holes like Sagittarius A star exist, but that these bizarre invisible objects may be the ultimate galactic protagonists.
Stunning CGI takes us back to witness the fiery origins of our galaxy’s black hole 13.6 billion years ago, when the early universe was home to colossal blue stars, and when they ran out of fuel, they collapsed under their own enormous mass, crushing down into an object so small and so dense it punched a hole in the fabric of the universe. Over billions of years, Sagittarius A star feasted on nearby gas, stars, and through cataclysmic mergers with other black holes. A breakthrough discovery by Nasa’s Fermi gamma-ray telescope has shown that our black hole had the power to sculpt the entire galaxy, creating vast bubbles of gas above and below our galaxy and even protecting stars systems as ours.
In a mind-bending conclusion, Brian Cox reveals how our modern understanding of black holes is challenging our concepts of reality to the breaking point. In trying to understand the fate of objects that fall into Sagittarius A star, scientists have come to a stunning conclusion: space and time, concepts so foundational to how we experience the world around us, are not as fundamental as we once thought.
