Rare clouds high in the Earth's atmosphere turned the night's sky a vivid blue yesterday as summer sunlight was scattered by tiny ice crystals. Pictures captured in northern England show the midnight skies illuminated with an electric blue colour.

The phenomenon was caused by rare noctilucent clouds - extremely small ice crystals that form in the mesopause - that sit more than 47 miles (75km) above the Earth's surface. These clouds, which are the highest in the Earth's atmosphere, scatter the sunlight as it dips low in the sky, creating an eerie glow. They usually occur in the weeks around the summer solstice when sunlight dips just below the horizon to illuminate the clouds.
