Diana and Ben take the bridge this week for a journey around the world and out into space, with a selection of the best science from the Naked Scientists worldwide travels. We find out how planets form from stardust in just tens on millions of years, and how to use winks, wobbles and blips to find planets around distant stars. We find out why the James Webb Space telescope must be very cool to pick up the hot infra-red radiation of deep space, and how the ExoMars rover could take us to previously unseen parts of Mars. Then we come back down to Earth with a bump (or should that be burp?) to discover the astronomical effort it takes to feed the population of the Olympic Village.
