Everything except visible light is false color: the raw data is just brightness, and I picked the colors. All the maps were reprojected onto the same equirectangular grid with the galactic center in the middle.

Photos come from Wikimedia Commons with their backgrounds removed; for the red blood cells and the snowflake I cut out just one. DNA, the atom, the nucleus and the proton have no usable photos, so they’re illustrations. The soap bubble is drawn too, its colors computed from the thin-film interference formula.
