A Great Comet Sets

Comet McNaught, a comet discovered by British Australian astronomer Robert H. McNaught, sets behind Mount Paranal, Chile in 2007. The comet, nicknamed the Great Comet of 2007 was visible to the naked eye for southern hemisphere viewers. The comet was the brightest seen from Earth for 40 years, and researchers later discovered Comet McNaught to be the largest ever measured.
