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)

Light and Dark
Today's Astronomy Picture of the Day focuses on one of my favorite things in the winter sky of the northern hemisphere: the Orion Nebula, Messier 42, in the constellation of Orion. Nestled within the larger complex is a dark nebula known as the Horsehead. Also can be seen the Flame Nebula, the Running Man Nebula. Can you find any shapes?
