This video takes us around the Moon and shows how it is illuminated not only by the brilliant light of the Sun but also by light reflected from the Earth. The trip starts on the side facing away from Earth where part of the surface is brightly illuminated by the Sun but the rest is totally dark. Moving around the Moon, the Earth rises, and its reflected bluish light illuminates the Moon’s surface. This dull glow is the earthshine. (You can clearly see it from Earth when the Moon appears as a crescent in the evening or morning sky.) When the Sun emerges from behind the Moon, the brilliant crescent is seen, but the earthshine is still faintly visible.

  1. Oh, look!

    DUMBFUCK posted another OMG PLAGIARISM!!! story (SAFE LINK to archived post) at Billy Boy Unread.

    Looks to me like the nancyboy wannabe badass plagiarized a Rolling Stones album title without giving credit…

    Methinks that’s sort of QUEER.

    (Yes, you DUMBFUCK – I am mocking you. With no small amount of glee and satisfaction)

  2. I recently heard of a man who faked having a serious disease so that he could get out of helping his sick wife from dealing with the daily chores. He went so far as to pee and poop his pants to reinforce the lie. Sad!
