Our grey moon.

reply to post by Sinter Klaas


I honestly cannot fathom why you would post such a silly thing.

Obviously the ISS is out of the atmosphere (it couldn't stay in orbit otherwise).

In the photograph, the line-of-site between the ISS and the Moon clearly passes above the atmosphere (that fuzzy blue thing that attenuates to blackness).

I chose that particular photo specifically because it shown the Moon as viewed from above the atmosphere (and because it was pretty - sue me ). If you want one from ISS looking well above the atmosphere, then here:

Could you please clarify your statement?

Here's what it looks like when the subtle colors are exagerated. The colors aren't fake, they are boosted to make them more visible.

I like the NASA picture with exaggerated colors, and also the picture Rogelio Andreo took from his front yard and modified similarly (So you don't really need NASA to try this at home):

Is the moon really like this? Well, sort of. This is what happens when you take a picture of the moon, neutralize the colors (so the median of the values of R, G and B is the same) and then saturate the image. So in a way, yes, those colors are real, and the only difference is that they've been exaggerated a bit. This was the first time I attempted to take a "colored moon" photo, but I enjoyed it so much I expect to do some more in the future

The moon colors must be subtle and Mars red must not be so subtle because Mars looks pretty red to me from my backyard, even though it's a lot further away than the moon.

It really looks like the atmosphere extends higher then where the picture is taken. It also looks like the moon is in front of the part of the athmosphere it's still behind.

I'm no idiot It just looks like it.

If you take the time to look at the video jazz10 has posted and also a phage posted pictures in the very first few replies.

You would see there is an explanation given why it looks grey from here and from the ISS.

If you are half way to the Moon it seems from there colours just fade away. ( looking at Earth.)

I believe this would have to do with resolving power of the human eye, or the optics used for the pictures that are taken with.

Thanks for the clarification, SK. You had me spinning for a moment!

I'm at work and can't view vids.
