Pages: 13 (including cover and credits). Sizes: A4 (210 × 297 mm) and US Letter (8.5 × 11 in), both PDFs included in one zip.

Printing: Print at 100% / actual size on A4 or US Letter, so nothing gets squashed. Inside pages use light backgrounds and print well in black and white; covers are dark, so start from page 2 to save ink.

Every fact is checked against Encyclopaedia Britannica, the US Department of Energy and NASA Glenn Research Center (checked 3 Nov 2026), and the sources are listed on each pack’s credits page. All drawings are our own; there are no photos in this pack. Drawings, puzzles and layouts are REALLYBYTE’s own work. Not endorsed by any of the sources.
