The team explores one of the greatest discoveries of modern astronomy - that our universe is expanding - and the new questions it raises about how the cosmos works. In the 1920s, astronomers studying galaxies realised they were moving away from us, with the most distant ones receding the fastest. The conclusion was revolutionary: space itself was stretching, and the universe was expanding in every direction. But once this discovery was made, a new challenge emerged – how fast is the universe expanding, and what could that tell us about its age, size and ultimate fate?

Three, two, one, lift off! This edition launches into the extraordinary - and extraterrestrial - world of astronaut training, discovering what it truly takes to become a European Space Agency (ESA) astronaut. As Europe looks to play a more prominent role in space exploration, we shine a spotlight on the candidates who are pushing boundaries and preparing to represent Great Britain and Northern Ireland amongst the stars.
