Light pollution is hindering a starry view of the night sky for more than half of people across England, a cosmic census has found.
Fifty-seven per cent of stargazers struggled to see more than 10 stars, while just 2% of participants said they experienced “truly dark skies”, enabling them to count more than 30, according to the research by the Campaign to Protect Rural England (CPRE).
People in towns and the countryside were encouraged to count the number they could see in the sky with the naked eye within the constellation of Orion, which is only visible in the winter months.
It's the final countdown – just two days left to take part in the #StarCount2019! 💫✨
The weather looks set fair and there should be clear skies for many of us this weekend. Get outside and help us reclaim our dark skies.

The results of the star count, supported by the British Astronomical Association, demonstrated the problem of light pollution and how it affects “one of the countryside’s most magical sights – a dark, starry night sky”, campaigners said.
Results of the research to map England’s night skies suggests more can be done by Government, local councils and the general public to lessen the negative effects caused by artificial light from streets and buildings, the group added.
Emma Marrington, dark skies campaigner at CPRE, said: “We’re hugely grateful to the many people who took the time to get out and take part in our star count.
“But it’s deeply disappointing that the vast majority were unable to experience the natural wonder of a truly dark sky, blanketed with stars.
“Without intervention, our night sky will continue to be lost under a veil of artificial light, to the detriment of our own health, and the health of the natural world.
“The Star Count results show just how far reaching the glow from street lights and buildings can be seen.
“Light doesn’t respect boundaries, and careless use can see it spread for miles from towns, cities, businesses and motorways, resulting in the loss of one of the countryside’s most magical sights – a dark, starry night sky.”
She suggested better-designed lighting, street light dimming schemes and part-night lighting, done in consultation with local communities and police, could provide an opportunity to limit the damage caused by light pollution, reduce carbon emissions and save money.
– CPRE said the star count, which ran for the first three weeks of February, involved 2,300 people.
