The grandest comet of the 21st century so far was Comet McNaught, the Great Comet of 2007. (Unfortunately for those of us living in the northern hemisphere, its splendour was reserved for the southern hemisphere.) The coma and tail of the comet
are among the wonders in this incredible mosaic with Patagonia (Argentina) in the foreground and a breathtaking dark sky above.
Besides what looks like zilliions of stars, there's the southern Milky Way arcing up from the left. On the righthand side of the picture you can pick out two nebulous (cloudy) bodies. They are two neighboring galaxies - the Large Magellanic Cloud and the Small Magellanic Cloud.
