Tukuk-OS🌌 Sky & Space
Five micro-lessons · about 37 minutes in total
Read the night sky like your grandparents could — stars, Moon, planets and eclipses. Five lessons, about 37 minutes in total — read one at a time; each stands alone.
The five lessons
1. Reading the Night Sky
Why stars rise and set, what constellations really are, and how light pollution erases them.
2. The Moon, Phases and Tides
Phases are geometry, not shadows — and the same Moon drags the oceans twice a day.
3. Eclipses — Rare Maths in the Sky
Why eclipses don’t happen every month, and the only safe way to look.
4. The Five Wanderers
What makes a planet a planet, why Mars loops backwards, and why only five are visible.
5. Stars Are Clocks
Light-years, the Sun’s midlife, and why the iron in your blood came from explosions.
