  • Researchers from the German "Loss of the Night" project have developed an app for Android smart phones, which counts the number of visible stars in the sky
  • The data from the app will be used by scientists to understand light pollution on a world wide scale.
  • The smartphone app will evaluate sky brightness, also known as skyglow, on a worldwide scale
  • ...7 more annotations...
  • This data can be used to map the distribution and changes in sky brightness, and will eventually allow scientists to investigate correlations with health, biodiversity, energy waste and other factors
  • The app works by interactively asking users to say whether individual stars are visible. By determining what the faintest visible star is, the researchers learn how many stars are visible at that location, and by extension how bright the sky is
  • With this app, people from around the world can collect data on skyglow without needing expensive equipment
  • some of the testers found that without intending too they learned the names of several stars and constellations
  • is based on the widely used Google Sky Map application
  • development of the app was sponsored by the German Federal Ministry of Research and Education,
  • satellites that observe Earth at night measure the light that is radiating into the sky, not the brightness that is experienced by people and other organisms on the ground

  • GLOBE at Night is a citizen-science project to raise awareness of the impact of light pollution by inviting citizen-scientists to make naked-eye observations of the night sky in your area.
  • Participating in GLOBE at Night requires only five easy steps
  • Find your latitude and longitude
  • ...6 more annotations...
  • Find Orion, Leo or Crux by going outside more than an hour after sunset (about 8-10pm local time).
  • Match your nighttime sky to one of the provided magnitude charts.
  • Report your observation.
  • Compare your observation to thousands around the world
  • You can also use the new web application data submission process
  • People in 115 countries have contributed over 75,000 measurements during the past six years
