The Sun lights the globe where it really is (wwwroot/js/sun.js, the Astronomical Almanac's low-precision solar coordinates): the day map shaded by the Sun's height and the Earth–Sun distance, warm city lights on the night side, and a twilight blend about 13° wide between them. It shows now, refreshed every 30 s, or the moment of the hovered, focused or pinned post: a click on a card pins it, and the subsolar point travels there the shorter way round. The panel's top corner shows that moment, the phase of the day and solar time at the post's place, and the season in its hemisphere (or in both, for a post without a place). Its tooltip shows the subsolar point, declination, axial tilt, distance, irradiance, day length and the next equinox or solstice. Land borders are thin paths. Country names are in the reader's language and appear as the camera comes closer: largest countries first, away from the globe's edge, never overlapping. They come from world-atlas 2.0.2 (Natural Earth 1:50m), prepared by tools/globe/prepare-countries.py, and are vendored with their hashes in SOURCES.md.

The globe's vendored files
Copied once on 2026-10-04 from the npm registry (registry.npmjs.org) and, for the day texture, from NASA
(eoimages.gsfc.nasa.gov); the build and the app never fetch them from anywhere else. To update, download the new files,
copy them the same way (the day texture through tools/globe/prepare-day-texture.py, the countries through
tools/globe/prepare-countries.py), and replace the hashes.
NASA's mosaic does not wrap cleanly at the 180° meridian near the poles (a lighter strip at its east edge), which the globe, drawing each pixel at its exact place, shows as a line from each pole; the script blends that strip into the map on both sides, only on rows where the two sides agree, and gives the rows within half a degree of each pole one colour.

globe.gl.min.js bundles its dependencies: three.js r185 (MIT, © 2010–2026 three.js authors), three-globe (MIT, © 2019
Vasco Asturiano), @tweenjs/tween.js (MIT), kapsule and accessor-fn (MIT, © Vasco Asturiano), and d3 modules (ISC, ©

Country names are not in countries.json beyond Natural Earth's English ones: the globe asks the browser
(Intl.DisplayNames) for each two-letter code in the reader's language, and falls back to the English name for the
few areas without a code (Kosovo, Somaliland, Northern Cyprus, …).
The service worker leaves this folder out of the offline precache (service-worker.published.js): the feed page
loads it the first time it shows the globe.
