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)

Two Comets
Today's Astronomy Picture of the Day is a beautiful southern sky view of two visitors to our neck of the woods. Comet Lemmon (C/2012 F6) and Comet PANSTARRS (C/2011 L4) are now coming into full view in southern skies. Both will move slowly into the northern hemisphere, knock on wood. "Mouseover" the picture for additional information.
