Look to the skies and count what you can see as part of our annual Star Count
Each year, CPRE asks the nation to help measure light pollution in their area by getting starry-eyed with us and counting visible stars. Ready to help out and have fun?
We think that dark and starry skies are a special part of our countryside. Nothing beats looking upwards to see velvety blackness, with twinkling constellations as far as the eye can see.
Our buildings and streetlights emit light, though, and this can affect our view of truly dark skies. We want to make sure that we can all enjoy starlit nights, and we need your help in measuring what effect light is having on our views of the galaxy.
The best way to see how many stars we can all see in the sky is… to count them! So we’re asking people from all across the country to become citizen scientists and look heavenwards from home for one night. Join in by choosing a clear night between 6-14 February 2021, looking up at the constellation of Orion and letting us know how many stars you can spot.
This year we’re asking everyone to take part from home. You can stargaze from your garden, balcony, doorstep or even bedroom window.
Don’t worry: we’ve given plenty of support on how to do this. And once you’ve done your star-spotting, use this form quickly and easily send us your count – and then we get busy with our number-crunching.
Your results from Star Count help us make a map of where star-spotters are enjoying deep, dark skies. By showing on a map where light pollution is most serious, we can work with local councils and others to decide what to do about it. You can see the 2020 results, and the map of what we discovered, here.
Star Count is supported by the British Astronomical Association.

Remember, you can do your 2021 Star Count on any night between 6-14 February 2021.
