The International Year of Astronomy

On this week's stellar Naked Scientists we're staring out into space. We find out how technology developed to see inside your body can give a whole new dimension to pictures of deep space, we celebrate the launch of the International Year of Astronomy and discover a new type of dwarf galaxy formed from ancient primordial gas clouds. Also in the mix, overcoming peanut allergies, fat dinosaurs and disguised meningitis bacteria. Plus, we answer Sir David Attenborough's Question of the Week and Ben and Dave build a telescope!
