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)

Blizzard
Today's Astronomy Picture of the Day is of a very rarely caught snow event. It's a view from the ESA's Rosetta vehicle of "snow" around Comet 67P, Churyumov-Gerasimenko. Click on the image in the link to see a short loop of the snowfall.
