Did you know that the starry sky in Chattanooga is one of a kind? Seriously, no two places in the world have the same view of the stars — talk about local.

The thing is, it’s likely you’ve never gotten to fully appreciate the night sky. For example, if you live downtown, you probably won’t see:

Zodiacal lights, the cone of light above sunrise + sunset points
Meteor showers, like the Perseids in August, the Geminids + Ursids in December, and the Lyrids in mid-late April
The Milky Way, visible as a yellow-orange band of light in the night sky

In fact, we’re betting the sky at night is sometimes light gray or orange, and bright enough to read by. So, are we psychic? Well, maybe — but these are all effects of light pollution.

Light?!

Light. You may not think of light as a pollutant, but 180,000 people all pointing lights into the night sky can have a serious effect on natural cycles that rely on light + the stars. Think:

Birds that pathfind using constellations
Insects attracted to light (like a moth to a flame, you could say)
Plants that use light to know when to grow + shed leaves
All creatures (even humans) that rely on day-night cycles for sleep

Even setting aside the ecosystem, it’s hard to argue with the view. (For reference, the sky above the Tennessee Aquarium is a class 7 on the Bortle scale.)

Here’s something you won’t expect…

This is really good news. Of all the pollution that feels out of our control, light pollution is actually completely reversible. The International Dark Sky Association has resources to help you use artificial light conscientiously.

Swap harsh, unshielded lights with downward-pointing LEDs in a warm color.
Consider what needs to be lit, and how much.
Support local light pollution policy.
