Comet McNaught stretches and shines high above Houghton Bay, on the southern coast of Wellington, the capital of New Zealand. 'C/2006 P1 (McNaught)' — its designation by the International Astronomical Union — was discovered in August 2006 by Robert H McNaught, during a survey of asteroids that might represent a threat to our planet. From August to December of the same year, this non-periodic comet remained invisible to the naked eye. In the weeks that followed, Comet McNaught' increased dramatically in brightnest, to the delight of stargazers and photographers living in the Southern Hemisphere. As the Sun's light passed through the tail's dust and ice crystals, a phenomenon called 'forward scattering' amplified the comet's visibility, making it one of the brightest since Ikeya-Seki in 1965.
