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)

Sungrazer
Today's Astronomy Picture of the Day is a view from the long-running SOHO (Solar and Heliospheric Observatory) satellite that has been observing our home star since 1995. Over that time it has discovered some 1,500 comets, including many like the one pictured, a "sungrazer". Not all sungrazing comets survive their encounter with that really big gravity well!
