Airglow: The Sky is Never Completely Dark

August 15, 2018

How we can see on a moonless night? (The answer is not the stars or planets.) The air itself is glowing and letting you see! 

Indeed, the night sky is never completely dark, even after starlight and sunlight are removed. Listen to Bob Berman who will explain—and astound you!

Note: Bob has a short advertisement (for audiobooks) upfront.
