For many the milky way Is out of sight
Light pollution around high population areas is washing out the night sky
Skyglow is created by light, mostly from urban areas, directed upwards into the nighttime sky. As a result as much as one-third of the world's population can no longer see the Milky Way in the night sky. But perhaps the greater concern is the entirely unknown ecological impact on nocturnal animals who can't hide in the dark from predators.
Dr. Kyba hopes that awareness of the issue will lead to light pollution mitigation efforts, like shielding lights and reducing artificial safety lighting to the minimum amount required in a given area.
