This is a composite image taken at Death Valley by the National Park Service. The change in our night sky is changing in dramatic ways much faster than we’d like to believe.
What is shown is a composite of 30 photographs giving us an 360 degree full sky panorama over Death Valley, purported to be the darkest place on earth. This photo gives us pause for concern.
Just as quickly as the night sky is disappearing due to light pollution, we have the power to change it.
Lighting manufacturers are taking their cue from the IDA and their customers giving consumers many wonderful choices now. We may have to pay a little bit more to get the security we desire initially, but in the long run we save not only money but our relationship with our neighbors. The nighttime environment benefits as well with lighting fixtures that eliminate light trespass and glare.
With less glare, we are creating a more secure environment. This is because, for one thing, the bad guys don’t get to hide in the glare of a cheap spot light. You see, your eyes need to be able to make the transition from your indoor light to your outdoor light. Heavy glare prevents good sight transitions while contributing to night sky pollution.
