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)

It's a Gas Gas Gas
Today's Astronomy Picture of the Day is a short video that shows the odd behavior of a solar prominence as observed by the Solar Dynamic Observatory vehicle.
