Loss of the Night
|Help scientists measure, understand effects of light pollution.|
|Use free app to identify as many visible stars as possible.|
How many stars can you see where you live? The Loss of the Night App (available for Android devices) challenges citizen scientists to identify as many stars as they can in order to measure light pollution. The app is fun and easy to use, and helps users learn constellations as they contribute to a global real-time map of light pollution.
Stargazing is a fantastic way to engage young scientists, but this ancient past time has become increasingly difficult in growing urban areas. Help scientists understand the effects of light pollution and learn about your night sky!
You don't need to leave the city to take part, in fact, the app is designed specifically for use in very polluted areas.
The more stars you observe, and the more often you run the app, the more precise the data for your location will become. As the seasons change so do the stars in the sky, and since there aren't so many very bright stars it is extremely helpful if urban users do measurements in each season.
