These great hollow globes of artificial super-metals, and artificial transparent adamant, ranged in size from the earliest and smallest structures, which were no bigger than a very small asteroid, to spheres considerably larger than the Earth. (Olaf Stapledon, STAR MAKER)

Clouds and Curtains
Today's Astronomy Picture of the Day shows noctilucent clouds and auroral activity over the skies of Canada. I've seen noctilucent clouds on a pretty regular basis but the Northern Lights more rarely. On the few occasions when they have journeyed this (relatively) far "south"...amazing things happen in the skies!
