New discoveries help experts in their search for the first alien moon outside our solar system, which could be Earth-like worlds with the potential for life; they haven't found any, but 21st-century methods might change everything.
Voyager has had a profound effect on our knowledge of the cosmos. Its mission was supposed to last five years but remains ongoing, fundamentally changing our understanding of the solar system. Featuring contributions from key scientists, we’ll explore what’s been achieved and what happens next.
2016 • Astronomy
The new discovery of seven alien Earth-like planets in a faraway solar system is a major milestone in our hunt for extraterrestrial life, and experts investigate the secrets of TRAPPIST-1's mysterious worlds to reveal if we're truly alone in the universe.

Shocking new evidence has convinced some of the world's greatest physicists that the universe is a hologram. Using cutting-edge technology, they investigate the secrets of black holes and space-time to build the case for this game-changing discovery.
2019 • Astronomy
An exploration of the dramatic fate of our future descendants, the technology they'll need to survive the end of this world billions of years from now and our options for colonizing and starting again on a new planet somewhere far from Earth.
In August 2018 NASA launched the first ever mission to a star. A historic quest to explore the last great frontier of our solar system - the sun. This will be the fastest man made object ever created. A spacecraft that will travel 450,000 miles per hour. It's ground breaking mission, to fly into the 'atmosphere' of our star and revolutionize our understanding of it. This documentary will celebrate this world changing event. Exploring the amazing science of our sun and going behind the scenes of the NASA mission to reach it. Timed to coincide with the arrival of the probe into the sun's atmosphere (Nov 2018) and the huge media spike this will create, this documentary will celebrate a key moment in human history, humanities first attempt to touch the Sun.

The Sun created our Solar System and in a fit of cosmic cannibalism will engulf and destroy it. However, our Solar System will see many changes before the light of our star goes out. So, what will be happening with the planets over the next four billion years, before the Sun swallows us and them?
NASA has taken us to the outer reaches of our Solar System, but there are still many mysteries to explore. New probes are being designed to look at our sun, the deep oceans of icy moons, and perhaps even our closest neighboring system - Alpha Centauri.
Sagan discusses the story of the Heike crab and artificial selection of crabs resembling samurai warriors, as an opening into a larger discussion of evolution through natural selection (and the pitfalls of intelligent design). Among the topics are the development of life on the Cosmic Calendar and the Cambrian explosion; the function of DNA in growth; genetic replication, repairs, and mutation; the common biochemistry of terrestrial organisms; the creation of the molecules of life in the Miller-Urey experiment; and speculation on alien life (such as life in Jupiter's clouds). In the Cosmos Update ten years later, Sagan remarks on RNA also controlling chemical reactions and reproducing itself and the different roles of comets (potentially carrying organic molecules or causing the Cretaceous–Paleogene extinction event).
The first episode of this series focuses on a subject that has fascinated scientists for hundreds of years - stars. Right now in the Universe's giant furnaces stars are being born. See how their creation changed the cosmos forever, leading to planets and life itself.
