Next Monday is the start of the The Great World Wide Star Count. From October 1st through October 15th, you can report how many stars are visible in your location’s night sky. With these data, this project can determine the amount of light pollution in different parts of the world.
Why do we care about light pollution? Light pollution is a strong indicator of wasted energy. Lights, contrast, and glare all impact the number of stars that are visible in a given location. Only the brightest stars are visible when there is a lot of nighttime lighting. Many people in the urban locations have never seen the Milky Way.
The project is an opportunity to encourage astronomy education and great example of collaboration via the web.
