Dr Jane Rigby: Nasa’s biggest ever telescope to launch - a podcast by RNZ

Later this month the James Webb Space Telescope will be shot into space, and when it reaches its destination - approximately 1.5 million kilometres from Earth - the massive telescope will slowly unfurl to its full size. All going to plan, it will allow us to see further into the Universe than anything else ever built, succeeding the Hubble telescope which has been orbiting the Earth since 1990.
