Almost a crescent. A moon of the late 1800s.
An astronomical drawing from the French-born Harvard researcher who, as an entomologist (as well as an astronomer), unleashed the horribly invasive gypsy moth on North America’s unsuspecting forests. He was trying to make silk. Oops.

How a young person can launch “any number of air balloons” without the risk of setting the neighbors’ corn ricks on fire – by using a gas stove with a chimney like this one.

Though it looks like postmodern architecture (Eero Saarinen, maybe?), this is actually inside your salad.
It’s a helical granum of a thylakoid stack, the part inside a plant cell – inside a chloroplast – where photosynthesis takes place. A thylakoid membrane forms a package inside which one thylakoid disk is stacked on top of another. The stack is called a granum. Some of them, like this one, make a kind of spring-like spiral… so not only do leaves fall in fall, but at…
Science Art: Nitrogen with Secret Binary Robot (Brain Freeze Ice Cream Wallpaper Detail), editor's own work.

The decor is delightful, though.

Over a million people could live here, in a double-cylinder colony in space.
From the NASA Ames Research Center’s concepts of future space colonies (as imagined in the 1970s).
