Dr Maggie Aderin-Pocock MBE is a space scientist and the author of 'Star Finder for Beginners'. Maggie joins Dan in the studio to chat about stars - from what stars actually are to how you can spot incredible constellations by looking at the night sky.

We also travel back to the Big Bang to discover how the Earth was created, explore some killer lakes in Africa and find out what amazing discovery was awarded a Nobel Prize in Chemistry this week (which is basically like the Oscars for scientists)!
