 | | This glow is called "earthshine." And scientists have been using this ghostly glimmer to measure the total amount of light reflected by our planet. |
 | | And the brightness of this part comes from light, which is reflected on the dayside of the earth and is bounced toward the moon, and bounces back toward the night side of the earth. |
 | | Now, what we see on the earthshine, over 50 years, the change is about 5.8-6 watts per meter squared, which is more than two times that, of energy that has been allowed to reach the atmosphere, and the ground, which before, at the beginning of the eighties, was actually reflected outside. |
