Oooh....
check out this find from NASA
what the hell? they think it's from water. maybe a rock slid down the mountain.
anyway, besides that; why is the sky always black on the moon? don't they have blue skies like earth? I know THAT particular pix is from orbit but remember when armstrong stepped out of his capsule?
do you see blue sky? no.
why is that!

I want to say that the sky is blue because of the reflection from the oceans and other water sources. I don't recall where I read that or who I may have heard it from, so I cant guarantee its accuracy, but that would also explain whey the sky isn't blue on the moon - theres no body of water to provide the blue reflection.
As a former science teacher, I can say with some certainty that the sky is blue because of the filtering of sunlight through the atmosphere. Most of the longer wavelengths (red, orange, yellow) pass right through the atmosphere, but the shorter wavelengths reflect off the particles and "catch" the blue light, making it seem blue. The moon has an extremely scant atmosphere, so there isn't anything to scatter the light. As an interesting aside, the sun looks yellow here, but on the moon it looks pure white (all of the color wavelengths mixed together make a white light).
i think it's all one big conspiracy!
Wow. thanks Jenny and Vanessa.
i'm clueless about that stuff but am fascinated by it.
a science teacher. that's what i'd love to be...science is very cool.
cuz there is no water to reflect into the sky. duh! :D
On Mars, the sky is blue in the morning, red during the day, then blue again at night.
