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)

Southern Comet
Today's Astronomy Picture of the Day is a very nice shot of Comet Lemmon (C/2012 F6a) sweeping across the stars of the Southern Hemisphere. Globular cluster 47 Tucanae and the Small Magellanic Cloud are also visible here.
