Audio Slideshow: Storm on Saturn

In the remote Australian Outback, a retired miner has found himself the toast of the
astronomical world by capturing rare pictures of an electrical storm on Saturn. Trevor
Barry's images have attracted interest from Nasa's Cassini mission to the planet.

Here the amateur astronomer, from Broken Hill, New South Wales, explains the significance of
his Saturn pictures, and why he is so passionate about the night sky.
