Light pollution 'saturates' UK's night skies

Half of the UK's population cannot see many stars because the night skies are still 'saturated' with light pollution, campaigners have warned.
Some 53% of those who joined a recent star count failed to see more than 10 stars in the Orion constellation.
That had decreased only very slightly from 54% since 2007, the Campaign to Protect Rural England and the Campaign for Dark Skies said.
The problem remained despite attempts to curb street lighting, they said.
