If you are in search of some natural wonder today, we suggest looking (not directly) at the sun. It is presently at the height of its 11-year activity cycle, and has been flaring up with frequency. Several recent solar flares were strong enough — had they been directed at the Earth — to interfere with satellite communication and prompt radio blackouts. And, as if to compensate for the potential inconvenience, such major solar flares also tend to produce gorgeous auroras. Wired has more detail, and some beautiful photos to demonstrate what colossal amounts of radiation being flung from the sun’s surface looks like.
