slide show: aurora borealis
Ooh, there's a truly outstanding and beautiful slide show of the Aurora Borealis at Virtual Finland (from where I've borrowed this photo)!
"Finland is a leader in the study of the Aurora Borealis, the majestic display of colours that adorns the northern sky. The hub of auroral science is the Sodankylä Geophysical Observatory, SGO, in northern Finland, a centre of excellence in geophysics and related disciplines. Experts share their knowledge with Virtual Finland visitors, explaining fact and fiction regarding this cosmic wonder. And when you see our sensational images you'll know why this is VF's number one site, with millions of visitors around the globe." Go see the slide show and then read the accompanying fascinating articles.
