On a clear night in central Idaho, you can see the sweep of our own Milky Way galaxy split the velvet sky. Although we now know the observable Universe spans 13 billion light years, in the 1920s, astronomers didn’t even know how big the Milky Way was. In fact, many astronomers believed our galaxy comprised the entire universe and that what we now know as different galaxies were just strange nebulae within the Milky Way. The story of how astronomers finally took the true measure of the Universe as a result of the the tireless efforts of a human computer.

The dramatic growth of the Treasure Valley impacts more than just commute times. The glare from our shining cities also obscures the night sky. And, like other forms of pollution, light pollution respects no municipal boundaries. Treasure Valley’s bright lights and big cities are starting to affect the night skies in the nearby Central Idaho Dark Reserve (CIDSR). Here are some of the details of our local light pollution and ways we can help mitigate its effects.
Much of the information here comes from this report written by the students from the UCLA Institute of the Environment and Sustainability.
