FACT
The breath-taking, shimmering nights of the Aurora Borealis was first named
by Galileo Galilei in 1619 as a combination of Aurora, the Roman goddess of
the dawn, and Boreas, the god of the north wind. The lights are revered world-
wide and it has been theorised that some of the 'impressionistic' cave drawings
actually depict auroras in the sky.
