This is Jupiter’s watery (well, icy) moon Europa, as pieced together in realistic color from a bunch of photos taken by NASA’s Galileo spacecraft in the 1990s.

It’s not necessarily super hospitable from a human perspective, but it’s one of the likeliest places in the solar system to find life we’d recognize.

There are oceans of H2O under that layer of ice….

Science Art: "De Motib. Stellae Martis" from Astronomia Nova aitiologetos, by Johannes Kepler, 1609.

This is a diagram of how Mars appeared in the sky, as observed by Johannes Kepler (and his boss, Tycho Brahe). The question Kepler ultimately answered was why did a planet moving in what should be a perfect circle (’cause God don’t make no imperfections) have these weird moments where it seemed to go backwards. Kepler’s answer: they moved perfectly, but not in a circle. They moved in an ellipse, which was a holier shape because instead of having one center, it had two foci, …

Types of head works for mines. These frames helped draw out the rocks that the miners were busy breaking up deep underground. At the time this book was published, many head frames were made of timber; these, based on working mines in Montana, were made of steel.

Science Art: Denisova Phalanx distalis

Replica of a Denisovan finger bone fragment, originally found in Denisova Cave in 2008, at the Museum of Natural Sciences in Brussels, Belgium.

A finger-bone from the other archaic humans – besides Neanderthals, there were Denisovans. And one of the fragments we know them from looked like this, found in a cave in what’s now Russia.

We put our own past together like a puzzle.
