Reading material from the people building Luna — circadian biology in plain English, the strange history of red light, build logs, and the occasional rant about minimum brightness.
SCIENCE
A short field guide to ipRGCs, melatonin, and the wavelength that runs your sleep — without the supplement-store pseudoscience.
FIELD NOTES
Observatories have used deep red light since the 1940s. The reasoning is older — and it's the entire technical foundation of Luna.

A weekly email from the people building Luna — usually 400 words, sometimes a recipe for getting off your phone earlier. Unsubscribe at the bottom of every one.
