Starry starry night....
In fact, I reckon so many people are probably unaware that it CAN be seen with the naked eye.
It's all because of light pollution. We live in towns and cities apparently 'saturated' with street lighting, which is making those natural wonders almost invisible.
And just in case you think that turning down the street lighting might encourage more crime, apparently in Saffron Walden in Essex, police have reported that street crime actually reduced by half when the council turned off the street lights at night.
Food for thought?
