Megan Eaves-Egenes grew up under the very starry skies of rural New Mexico. During those years, she developed a deep appreciation for astronomy. 

The fascination is, of course, not hers alone. But, a starry sky requires one pretty important ingredient: darkness. One study recently reported that since 2011, the night sky has gotten brighter at about 10% per year.

All that light pollution has brought dire consequences to life on planet earth. Crickets can’t tell whether it’s day or night, bird migrations have gone haywire, and our own natural alarm clocks are constantly confused. 

In a world where switching on a lamp during evening hours is, as Megan writes, “almost as basic as breathing” is there hope for our night skies? Or have we illuminated our way to a point of no return?
