America's rapid adoption of LED lighting saves money and uses less electricity. But it's also making it harder to see the stars.
Light pollution comes from excessive artificial light that causes the sky to glow and obscures the light of the stars, and the problem is growing fast. New research in the journal Science found the night sky is getting 10% brighter every year.
Experts say much of that light pollution is driven by the growth of cheaper, cleaner and brighter LED lighting.
