✵✵✵✵✵What is EARTHSHINE?
The EARTH lights up the MOON? (Astronomy)
Have you ever looked up at night to see a crescent moon, and noticed the rest of the moon's surface is dimly lit? This is due to Earthshine!

The concept of Earthshine has more far-reaching implications. Astronomers can study the albedo (reflectivity) of surfaces here on Earth, and use it to estimate conditions on far-away planets outside of our own Solar System.
