Unknown: Cosmic Time Machine

Completing a four-part documentary series about quests to expand human knowledge – previous episodes have covered the mysteries of the Ancient Egyptians, the prospect of artificial intelligence being used in military contexts, and an archaeological discovery shedding new light on humans’ evolutionary ancestors – is a film about Nasa’s mission to launch the James Webb Space Telescope. The work of engineers and scientists is followed as a billion-dollar piece of kit is created – since its launch it’s provided stunning images telling us more about black holes, galaxies, planets outside our solar system and how the universe looked soon after the Big Bang.
