Stargazing

Some of the holiest moments of my life have occurred while staring into a starry sky at night. Gazing upward and taking in the endless existence of galaxies and the magical beauty of stars visible against the darkness brings me into a state of reverence like nothing else can. I don't take the time to do it enough, but I'm determined to change that.

I'm feeling a renewed passion for the majesty of the night sky after reading about IDA - the International Dark Sky Association. It turns out that all of the artificial lighting we use for everything from parking garages and highways to the fixtures on our homes contributes to light pollution (who knew?) which is defined by IDA as "any adverse effect of artificial light, including sky glow, glare, light trespass, light clutter and decreased visibility at night." (You can read much more about these issues on their website.) About two-thirds of the world's population, including almost everyone in the continental U.S. and Europe, no longer see a starry sky where they live, according to a recent Wall Street Journal article. This is tragic not just for romantics like me, but for the professionals. Scientists and astronomer's ability to study and observe the sky is greatly impacted, even with their high tech equipment.

It was interesting to read about the need for specified periods of dark and light, our circadian rhythms, that all of life requires for good health. Exposing ourselves or other species to artificial light can interrupt any natural ecological system. The most practical way for homeowners to reduce light pollution is to know about and use "sky friendly lighting" definted as "outdoor light at night used only when and where it is needed and at appropriate levels. Use fully shielded, light efficient fixtures aimed directly at the ground. And incorporate timers and sensors to shut off lights when not needed." The IDA works with lighting manufacturers and even has a seal of approval to help consumers recognize fixtures that will not contribute to the problem.
