Brian Cox and Dara Ó Briain host a live broadcast built around the night sky, opening a three-part series recorded over three nights of stargazing. The format mixes studio banter between the two hosts with feeds from observatories around the world, pulling in fresh images of planets, nebulae, and galaxies as they come in rather than relying on pre-recorded packages. Cox supplies the physics, explaining what viewers are looking at and why it matters, while Ó Briain keeps the tone light and asks the questions a non-scientist would ask. Astronomers join remotely to talk through what their telescopes are catching on the night in question, so the content shifts with whatever the sky actually offers rather than following a fixed script. This first episode sets up the run, framing amateur stargazing as something viewers can try themselves with nothing more than a clear night and a bit of patience.
