Comet McNaught is a one-hit wonder among comets. After lighting up the daytime sky in 2007, McNaught jetted and will likely never be seen again.
The brightest comet in more than 40 years, Comet McNaught earned the title of Great Comet of 2007.
Its spectacular tail was popular with camera-toting skygazers. It also shed light on the composition of comets when the Ulysses spacecraft flew through the tail in 2007 and discovered a decrease in solar wind.
The great comet's discoverer, Australian astronomer Robert McNaught, went on to discover another bright comet, McNaught C/2009 R1, which became visible to the naked eye in June 2010.
