This week on the Naked Scientists we cross hemispheres to explore galaxies far far away. Chris presents live from Johannesburg to discuss the South African Large Telescope whilst back in the studio we explore the effects of space travel on the body, the expansion of our universe and the possibilities of another planet earth. We also investigate effects on our hearing and bring you a special kitchen science that could be out of this world. Like this podcast? Please help us by
