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)

Deep North
Today's Astronomy Picture of the Day takes us to the Double Cluster in the constellation of Perseus. The winter sky in the northern hemisphere is often seen as dull for observers, nothing like the glories of the galactic center that we see in summer. However, it is not dull, just very, very subtle. Many glories await you in Perseus and other nearby constellations, as this image shows!

On the other hand, Fred, the longer nights of winter mean that the nighttime sky is visible more easily and for longer.
