The science

The sky most of Europe has lost

Over 99% of people in Europe and the United States live under light-polluted skies, and the Milky Way is hidden from more than a third of humanity. The Moroccan Sahara and the High Atlas are among the darkest skies within a few hours' flight of Europe.

Evidence: Strong

The light-pollution atlas is strong (satellite data checked against 20,000 ground readings). What stargazing does for wellbeing is weak.

What the studies show

The 2016 world atlas of night sky brightness combined satellite data with about 20,000 sky measurements from the ground. Over 80% of the world, and over 99% of people in the US and Europe, live under light-polluted skies. Its maps show the Sahara and much of southern Morocco among the darkest areas near Europe.

Feeling connected to the night sky went with better wellbeing in a survey of 406 adults, and people in light-polluted places felt less connected. That is one small correlational study. Night skies fit awe research (vastness), but stargazing itself has barely been studied.

In Morocco

Away from Marrakech's glow, a camp in Erg Chebbi (Merzouga) or Erg Chigaga (beyond Zagora) on a moonless night shows the Milky Way to the naked eye. Check the moon: a full moon washes out the stars. Desert nights from November to February are cold.

Oukaïmeden, in the High Atlas south of Marrakech, has a university observatory at about 2,700 m, and astronomers there have proposed an Atlas dark sky reserve around it. It is a proposal: as of 2026-11-14 we found no certified dark sky place in Morocco.

Where it stops

  • No good study shows that stargazing improves health or mood. We describe the sky, not a benefit.
  • We don't call any Moroccan site a certified dark sky reserve: none is listed by DarkSky International or the Starlight Foundation that we could find.
  • The atlas uses 2014–2015 data; skies have generally grown brighter since.
