The Sky at Night - Return to the Moon ? -  Nearly 50 years ago, Neil Armstrong stepped onto the moon and it seemed like the dawn of a new age. Soon we'd be flying to the moon as effortlessly as we fly to America, and a moon base would be filled with men and women building a better future out in space. But then the moon fell out of fashion. We soon realized it was brutally inhospitable and getting…

The Sky at Night – Guide to the Galaxy

Guide to the Galaxy: all good travel guides need a map, and the team unveil the most detailed 3D map of the Milky Way ever produced. A map that reveals that there may be 50 per cent more stars in the galaxy than we previously thought.     American astronomer Neil deGrasse Tyson gives us a guided tour of the strangest stars we have ever observed, and we discover that the Milky Way may already be colliding with our neighbouring…

Deep Down & Dirty: The Science of Soil

For billions of years our planet was devoid of life, but something transformed it into a vibrant, living planet. That something was soil.     It's a much-misunderstood substance, often dismissed as 'dirt', something to be avoided. Yet the crops we eat, the animals we rely on, the very oxygen we breathe, all depend on the existence of the plant life that bursts from the soil every year. Deep Down & Dirty: The Science of Soil In this film, gardening…

How the Universe Works: Mystery of Space-time ep.10 2018

Space-time is the secret structure that controls the universe, and this strange four-dimensional substance controls time, light, and energy. It will also determine how the universe will end.       Space-time In physics, space-time is any mathematical model that fuses the three dimensions of space and the one dimension of time into a single four-dimensional continuum. Space-time diagrams are useful in visualizing and understanding relativistic effects such as how different observers perceive where and when events occur. Until the…

How the Universe Works: The Quasar Enigma ep.7 2018

Quasars are the brightest and most powerful objects in our universe, and though they have shaped the cosmos, they might ultimately destroy everything that exists.     Quasar   A quasar (also quasi-stellar object or QSO) is an active galactic nucleus of very high luminosity. A quasar consists of a super massive black hole surrounded by an orbiting accretion disk of gas. As gas in the accretion disk falls toward the black hole, energy is released in the form of…
