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)

Fragile (Yes)
Today's Astronomy Picture of the Day shows The Soap Bubble Nebula, found in the area of NGC 6888, The Crescent Nebula, in Cygnus. This object was first identified by an amateur astronomer in 2008 (and independently found several days later by other amateur astronomers). Amateurs can contribute to the field!
