Astrophysics & Space

Midnight, gold, and the discipline of real ephemerides. Cosmic Aloha — research-notes-on-paper plates: an HR diagram with the white dwarfs where they actually clump, stellar spectra with feature-correct lines (Balmer for A-type, TiO bands for M, Ca II H&K for G), a genuine Hawaiian star compass, and constellations rendered as round dots of light sized by magnitude — the way a chart, not a cartoon, shows stars. Celestial Observatory — photoreal planetary bodies. Celestial Retro — the same sky, mid-century deco. Ground Track — for the orbital mechanics and satellite crowd: CR3BP zero-velocity contours with L₄/L₅ marked, Walker constellation rosettes, and a Molniya ellipse whose dots are solved from Kepler's equation, crowding at apogee like they should.

If you know why the dots crowd, this page is home.
