The problem
You live under one of the most
spectacular things in existence.
You've never seen it.
If you grew up in a city, or live in one now, you have probably never seen
a truly dark sky. Not a real one. The kind where the Milky Way stretches
overhead like a river of light, where you can count satellites and shooting
stars appear every few minutes.
Light pollution has quietly erased that for most of modern times. However,
it is still up there. It's just been stolen from you without you ever noticing.
And the handful of times conditions would actually be perfect to go find it —
a new moon, clear skies, a meteor shower — you never find out in time.
The information exists. It's just scattered across atlases, moon calendars,
weather apps, and astronomy forums that nobody has time to cross-reference.
People miss the most beautiful thing above their heads every single night.
The scale of what you're missing
Light pollution isn't just an inconvenience for astronomers — it's a near-total erasure of something humans have looked up at for our entire existence.
From a Bortle 9 city sky you can see roughly 20 stars. From a Bortle 1 dark sky — over 4,500.
Bortle Scale
Sky brightness classification
99% of the US and European population lives under light-polluted skies. One third can't see the Milky Way at all.
Falchi et al., 2016
Science Advances
"Seeing the Milky Way for the first time is one of the most reliably reported awe experiences in modern life."
