2021: Globe at Night Real-time Interactive Infographic
In 2021, Globe at Night received
from 90 Countries
& 52 US states
Data is submitted via mobile devices, as well as desktop & laptop computers
Data can be submitted via our web app on both mobile and desktop/laptops. Additionally, two native mobile apps - Loss of the Night (LON) for iPhone and Android, and Dark Sky Meter (DSM) for iPhone - support Globe at Night. You can view the breakdown of how many observations have been made from the various devices and methods in the charts above.
Distribution of Observations by Area
Use the dropdowns above to view the range of limiting magnitudes submitted for the given country or US state.
What happened to the Zero Limiting Magnitudes?
You can get a Limiting Magnitudes (LM) of 0 (zero) if you have extreme light pollution in your area, but you also may not be able to see any stars due to cloud cover. The pie chart to the right breaks down the reported Cloud Cover for LMs of 0, showing that the vast majority of those observations in 2021 (~70%) have been due to cloud cover of 50% or more. So we don’t show the zero LMs in the histograms.

Web App Translation Use Around the World
Globe at Night is a truly international project, with data submitted from around the world. To facilitate this process we have had the web app and other materials translated into many languages. In 2021, Citizen Scientists from around the world submitted their data in 16 different languages (other than English). You can see the results in the chart to the left. Choose a language from the menu below to see a chart of where the various languages have been used to submit data.
Want to get involved?
It’s easy - pick a clear night during a monthly campaign, and use our web app to submit your data. There are lots of things to learn on the website, whether you need help finding the constellation, or want to know more about light pollution, we’ve got you covered!
