The dark skies of the great outdoors help people to see the wonders of space, either with the naked eye or using telescopes. That's why observatories are usually placed in high altitudes or remote locations, where there's often outstanding natural beauty and little light pollution.

A report commissioned by the UK government recommended that every school child should be given the opportunity to spend a night under the stars in such places.

Learning that this band is made from millions of stars, each not too different to our sun, gives us a new appreciation of the universe and our place within it.

Perhaps they might spot the closest galaxy to ours—Andromeda, 2.5m light years away—and marvel at how the light they're seeing set off just before our species walked the Earth.

But protecting dark sky sites in national parks is only half the story. It's a shame that light pollution means these wonderful experiences are only possible far from home. Connecting everyone with the wonders of the universe should be taken up where people live.
