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)

M15
Today's Astronomy Picture of the Day is a wonderful shot from the Hubble Space Telescope showing globular cluster M15 in the constellation of Pegasus. This is one of the relatively few globular clusters you can observe in the fall or winter sky. In a "amateur" instrument it takes on the appearance of a swarm of bees or a sprinkling of diamonds.

"The Buck Rogers Globular Cluster" as I like to call it.
