A Video Clip That Caught My Attention

The title of this video is "What Colour Is The Moon?"
This video explains why we see a different colour of the moon on earth (white) while in space, astronauts see the moon as grey.
Three things that I learnt in the video:
  • The moon reflects about 13% of the light that hits its surface
  • Before the brain figures out what colour something is, they first figure out how bright that thing is.
  • The reason why we see the moon as white or bright as our eye has nothing to compare the moon with but the dark sky. Therefore, we see the moon as something bright.
