Drag your bones toward more Halloween-themed citizen science.
Growing up in the last green valley, I didn’t think too much about light pollution. We always brought flashlights trick-or-treating, and I can remember being afraid to go outside after sunset for fear of what could be hiding in the dark; we could always see the stars. After living in Boston, however, I realize that many people don’t get to experience this level of darkness, as light pollution in most urban areas is so intense that the constellations are obscured.
To help citizen scientists measure the light pollution around the globe, DDQ has developed an app called Dark Sky Meter. The app uses the camera of an iphone to measure sky quality, which is a meter for the darkness of the night sky. The app correlates the data from thousands of submissions world-wide and places them on a map. As Norbert Schmidt, the primary programmer describes, “We are creating a map of light pollution profiles, a high resolution map.”
As an amateur astronomer, Schmidt’s original motivation for designing the app was to help fellow star-gazers find the best places to set up their observations. He notes, “We don’t see stars anymore, any galaxies, or the milky way in city centers.” By creating an up to date database of the darkest areas, he and the DDQ team hope to create a “living map” of the best observation areas.
So this Halloween, if you’re not too scared of the dark, get outside and measure the sky quality in your neighborhood. Your submission will contribute to the work of astronomers and scientists around the globe.
