When we look up at the night sky, we expect to see the universe in all its glory — countless stars, the Milky Way, and maybe even a faint nebula or two. But for most of us, those views have faded behind a hazy glow. This glow isn’t natural; it’s the result of light pollution.
Light pollution is the excessive or misdirected artificial light produced by streetlights, buildings, cars, and advertising signs. Instead of illuminating the ground where it’s needed, much of this light spills upward and scatters in the atmosphere, creating a bright veil that hides the stars.
There are several types:
Skyglow — The general brightening of the night sky over populated areas.
Glare — Excessive brightness that causes visual discomfort and reduces contrast.
Light trespass — Unwanted light spilling into areas where it isn’t needed, such as a streetlamp shining into your bedroom or observing site.
Clutter — Bright, confusing groups of lights, like in city centers or along highways.
Even small towns produce enough light to wash out the faint stars that make stargazing magical.
Overly bright street lighting without shielding.
Outdoor security lights left on all night.
Commercial signs and billboards that stay illuminated after hours.
Unnecessary decorative lighting on buildings or in gardens.
Clouds and humidity, which reflect urban light back toward the ground.
Each of these adds to the dome of light that hovers above populated regions — visible even from tens of kilometers away.
Luckily, you don’t need to travel far to find a darker sky. The key is to get away from major sources of artificial light.
Here are some tips:
Head to rural areas — The countryside, coastal dunes, or forest clearings often offer excellent skies.
Check elevation — Hills or small mountains can help you rise above haze and distant glow.
Avoid full Moon nights — Even natural light can overwhelm faint stars.
Scout in advance — Visit the location by day to find safe parking and clear horizons.
If you’re in the Netherlands or nearby, great places include:
The Wadden Islands — some of the darkest skies in Western Europe.
Drents-Friese Wold National Park — certified Dark Sky Park.
Lauwersmeer National Park — excellent for Milky Way viewing.
Veluwe — good balance between accessibility and darkness.
Before heading out, check light pollution maps and weather conditions. These resources can help you find the perfect spot:
You can also help reduce light pollution in your community:
Use fully shielded outdoor lights that point downward.
Choose warm-colored LEDs instead of harsh white ones.
Turn off unnecessary lights when not in use.
Educate others — the night sky belongs to everyone.
Every light turned off helps bring back a few more stars.
