A new study has revealed a third of people on Earth can't see the Milky Way at night, due to light pollution.

An international team of scientists has created The New World Atlas of Artificial Night Sky Brightness - which shows 99 percent of those living in the United States and Europe live under light-polluted skies

University of Canterbury Emeritus Professor of Astronomy John Hearnshaw says this is a growing problem in New Zealand as well, mainly due to the way we light our streets.
