A star app has never been more beautiful and easy to use. Just hold it to the sky to automatically find constellations, planets, satellites and more. It’s stargazing fun for all ages and experience levels!
Globe at Night
TGlobe at Night is an international citizen-science campaign to raise public awareness of the impact of light pollution by inviting citizen-scientists to measure & submit their night sky brightness observations. It's easy to get involved - all you need is computer or smart phone.
Dark Sky Meter
The Dark Sky Meter measures the artificial sky brightness in two simple steps. Just cover the camera and aim to the point right above your head. The output is the same as a commercial Sky Quality Meter... But at a fraction of the price! The app can submit your measurements to the Globe at Night project and the International Dark Sky Association.
