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)

First Landing
Today's Astronomy Picture of the Day is a short video of the descent of Eagle (Apollo 11) to the Sea of Tranquility. (Artwork above by Robert McCall, depicting the descent, including inset views of what would have been seen from the windows of the Lunar Module. Artwork below by Pierre Mion showing the unexpected obstacle in the final part of the descent, when the Lunar Module came dangerously close to landing in a rock field)
