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.
