In this episode of Dark Sky Guardian, we learn how thoughtful lighting can reduce glare, save energy, protect wildlife, and restore our connection to the night sky.
"ASTROMAN: the Dark Sky Guardian" is a podcast channel that aims to explore popular science in multiple disciplines and research on interdisciplinary approaches, such as sustainability, dark-sky protection, astrophotography, space exploration, astronomy innovation, inclusive science communication, and STEAM Education by integrating science and arts.
Exodus CL Sit, also known as the ASTROMAN, is a transmedia astronomy educator, popular science author, STEAM educator, and science communicator in Hong Kong. He is recently the National Astronomy Education Coordinator (Chair of Hong Kong, China) of the International Astronomical Union and President of Starrix. He was also an International Committee Member of the Dark Sky International, regularly organizing public lectures at the Hong Kong Space Museum and the Hong Kong Science Museum. He was also the author of a popular science book "Decoding the Starry Night: A Guide to Stargazing and Astrophotography".

Welcome to Daskai Guardian. I am your host, Exolation On Seats from Hong Kong, China.
And today we are looking up, when was the last time you saw the Milky Way?
From all of us living in the cities or suburban areas, the nice guy is from back.
It's a hazy, glowing, orange, or gray. This is like pollution.
And it's redding at alarming rates.
But there is a movement growing, a group of guardians dedicated to reclaiming the stocks.
Today we are breaking down the Daskai poaches.
These are not just rules for astronomers. They are simple, intentional ways to change how we light up world to protect our health, our well-life and our heritage.
The first step in the Daskai approach is a shift in my sense.
We often think more light equals more safely.
But Daskai advocates that better light equals more safety.
Think about our bright, flight lights heating your right in your eyes.
Equate deep, dark shadow where you cannot see anything.
We call that just like some kind of clear.
The first apologies targeting.
Nice should only be direct down where it is needed.
On the sideway, on the doorway, not spilling out into the sky or into your neighbors that will wound them.
But using food issues, fixtures, or Daskai friendly light shoes, the lights that have a solid cap on top to keep the light on the ground and the sky grow out of the atmosphere.
Now let's talk about the light of your lights.
Have you noticed how many street lights have moved from a long yellow to a harsh lights?
Those are usually high intensity LEDs.
The second Daskai approach focused on the color and temperature.
Modern, by which white light is a major problem, it scatters more easily in the atmosphere, creating more chaos.
When portally, it's mimics daylight.
This met with our surf circadian vivums telling our brains to stay awake when we should be producing metatonium.
The approach here is an all-use warm color box.
We look for light with a color temperature of 3000 kelp or lower.
These amber tones are gentle on human eyes and far less disruptive to the nighttime animals like sea turtles.
And my graining birds will rely on the stars to dedicate the direction.
The bird approach is perhaps the most logical timing and controls.
In our modern world, we tend to set it and forget it.
We leave porch lights on all lights and office.
Viewing stay, illuminate long after the last end.
And Hawaii has gone home.
A Daskai approach utilizes technology to be smarter.
This means using motion sensor so to like only puffs on when someone is actually there and using timers or gamers.
Why keep apart late at FAM at 100% brightness?
By demon nights doing the quietest hours of the nights, we're so massive amount of energy and give the local ecosystem a chance to breath.
When we talk about being a guardian, it's about ensuring that life is an active choice, not a permanent backline noise.
Protecting a Daskai doesn't mean leaving in total darkness.
It means using light with intention.
By shielding our fixtures, choosing warm colors and using timers, we do something incredible.
We bring the universe back to our doorsteps.
We allow the next generation to look up and feel that same sense of wonder that our ancestors fell thousands of years ago.
If you want to start, look at your own front porch tonight.
Is it light spilling into the sky or is it pointing at the feet?
Avivov change is a victory for the nights.
Thanks for listening to the Daskai Guardian.
I'm Excellency of the China Hong Kong.
Keep your eyes and your eyes on the stars and enjoy the Milky Way and the beautiful night sky.
And a spectacular view in the night time.
Thank you everyone.

Without your passion and contribution, we won't be able to share the stories and inspire the worlds.
We invite you to join our community of storytellers and share your voice with listeners worldwide.
As we wrap up today's episode, we're looking forward to unraveling more stories from the universe.
With every new discovery from ground-based and space-based observatories and each milestone and space exploration,
we come closer to understanding the cosmos and our place within it.
Until next time, let the stars guide your curiosity.
