The Environment Agency has compiled guidelines that could bring back twinkling stars to the nation's urban skies.
The new guidelines ask local governments to draw up plans for their area's street lighting, and to reduce the use of such lights to allow a better view of the stars.
The agency points out that excessive lighting in urban areas disturbs astronomical observation, prevents sound sleep and disrupts the healthy growth of fauna and flora as a result of what the agency calls "lighting pollution."
