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 Image
Today's Astronomy Picture of the Day shows the first image transmitted by NASA's InSight lander from the surface of Mars. The lander (based on the design used in the polar-exploring Mars Phoenix mission and Mars Polar Lander) will emplace instruments on the surface and beneath the surface to get a better picture of what the interior of Mars is like.
