Star Count

From 21-28 February, countryside charity CPRE is running its annual Star Count.

To celebrate starry skies, and help protect our view of the stars, CPRE are inviting the nation to become 'citizen scientists' and take part in Star Count – a cosmic census that will help map our view of the stars and the impact of light pollution across the country.

A star-filled sky is one of the most magical sights you can see in our countryside. But light pollution means that many of us can't see the stars – only two per cent of people in England enjoy truly dark skies.


CPRE Star Count 2020 will help map impact of light pollution across the UK

Stargazers will be asked to count the number of stars they can see (with the naked eye) within the constellation of Orion, and submit their count on the CPRE website.

The number of stars visible within the constellation of Orion is a good measurement of the amount of light pollution in your area, and can be compared with previous years' data to show how our ability to see the stars is changing. The data will be used to lobby local councils to make changes to reduce the impact of artificial light.

To take part, just look up at the sky from 21-28 February and count how many stars you can see in the Orion constellation.
