What is light pollution?
Light pollution is a serious issue since it interrupts human and wildlife sleep cycles, results in
higher rates of cancer, and interferes with astronomers' scientific research efforts. Light
pollution is especially an issue in Valley Center, due to the community’s close proximity to Palomar
Observatory. Light pollution degrades astronomers' ability to observe the night sky, which is why excessive artificial light threatens the astrophysics research at Palomar Observatory. By working closely with the community, we hope to promote the use of good lighting in
order to mitigate these issues.
Good lighting provides all of the light necessary to serve its purpose and provide security, while
still being dark-sky friendly. It is a common misconception that more light results in more safety,
however, this is not the case. Safe, dark-sky-friendly lights are shaded in order to increase
efficiency and prevent light from going into the sky.
