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)

Comet ISON
Today's Astronomy Picture of the Day is a "positive" and "negative" image of Comet ISON from November 15. The comet has undergone a dramatic jump in activity (and brightness) and is clearly visible with a low power/high field of view device (binoculars, for example). A bit more of a jump in brightness and it should be visible (in dark skies).
