PacSci-Doku: National Reserve

The Answer

The question in this edition is:

What could be the newest national reserve in the United States?

The answer: Dark Skies

The United States has national marine reserves, bird sanctuaries, and botanical reserves. If astronomy enthusiasts have their way, the next reserve will be the Idaho Dark Sky Reserve, consisting of 900,000 acres in central Idaho. Light pollution across the United States, from streetlights, houselights, security lights, lit-up buildings and advertisement signs, means that most people can only see the brightest stars in the night sky. Almost 80% of people in North America cannot see the beautiful Milky Way stretching across the sky on a clear night. They cannot see the many faint gaseous nebula (like the Orion Nebula), and distant galaxies (like the Andromeda Galaxy) located across the night sky. The Dark Sky Reserve will guarantee that at least one place in the United States will have dark skies, no matter how much human develop occurs in the future. Read more about the Idaho Dark Sky Reserve and see images of the Milky Way from a light polluted area versus a dark sky location.
