But it won’t shine forever. One day, it will leave the main sequence, swell into a red giant, and make our planet uninhabitable. In this cinematic science documentary we explore the full timeline of the Sun, from stellar birth to extinction, and what that means for the future of life on Earth. Scientists now understand how our star will die — and they’ve mapped the chain of events that will reshape the solar system. From nuclear fusion at the Sun’s core, to the physics of heliophysics, solar storms, and Earth’s eventual fate, this documentary tells the story of a star… and what happens to everything that depends on it. What happens when the Sun runs out of fuel? How does the Sun’s energy sustain life and how will it end it? When will Earth become uninhabitable? And how do these scientific predictions align with what’s written in ancient texts like the Bible and the Quran? Is Elon Musk right that humans need to become a multi-planetary species? Narrated by Michael (a real human), and in 4K, this astronomy documentary blends cinematic visuals with real science — exploring stellar evolution, the death of main sequence stars, and the deep cosmic timeline we’re already living in. This is the science of how our world ends — and when. If you enjoy documentaries with Neil deGrasse Tyson, Brian Cox, or David Attenborough or shows like Netflix Cosmos, BBC Horizon, and PBS Space Time — you’ll hopefully enjoy this one too.
