No. It's from the northwest. I'm the second person to tell you this. You may want too look again.

You're right about craters, but those look convex to me.

Eta: notice the "man's" shadow and how it bends against the bump it goes over. If it was convex, it would bend he opposite way. It looks to match the others.

Actually, pectus is right. The light is coming from the southeast. Those are craters -- they go DOWN -- so the highlight happens on the side opposite the light source, i.e. the highlights are on the top left side, so the light is coming from the bottom right. If they were bumps, you would be correct, but they are not. So, yes, this "shadow" is facing the wrong direction. Whatever that is, it's not a man on the moon.

They are craters, but because of the crater edge, the shadow appears behind it to the "southeast." The way you can tell is opposite side of the crater is much brighter than the surrounding land, therefore the albedo (reflection of sunlight) is much higher.

The light is coming from the southeast. The cliff of the crater shadows the portion of the crater in which the sun's light is coming from. If light was coming from the northwest, the cliff of the crater would shadow the northwestern portion of the crater.

There's really no other way around it. Why else would the northwestern side of the crater shadow be lighter than the surrounding area?

Ok, lets say the sun is hypothetically out of the SE. Wouldn't the northwest side of the crater be darker than the surrounding area because of the shadow the ridge causes?

Instead it's a brighter shade of white. The ONLY thing that causes this is sunlight, therefore the sun can only be coming out of the NW

There wouldn't be visible shadows from the ridges on the southeast side if the sun was in the Southeast.

fricking aliens have no damn shame. Pee on the dark side of the moon.

Aliens have complete control of the moon per agreement. Even Russians and Chinese are ok on this one, although the Russians lost a few ships before they signed off. Man will never walk on Moon again

I keep looking at it and second-guessing myself.

Who knows.

The one feature that breaks the mold is the large one that gets the most white and most dark in the lower lefthand side.

The only way the crater's southeastern rim could cause a shadow like that (opposite of the other features) is if it had such a high rim that it left a convex shadow rather than concave and the sunlight had to be at a low angle. So maybe that feature is just a deep crater.

I still can't seem to make it make sense in my brain...so I decided just to worry about the other features.

Disregarding the shadow, the figure itself is very interesting.

A crater in cross section:

It's not the only one like that, if you look at the zoomed out image.



NASA comments on the issue

quote:

Petro says there is no nearby mountain or boulder that would cast the shadow. “My best guest,” Petro said in a statement to PIX11, “is that its something (dust, an eyelash, scratch on the negative) was on the film. Remember, this was in the pre-digital days when all sorts of nasty things could happen to film.”

So it has to be from the southeast?

Anyone else agree after this photo that those all can't be hills? Just deeper craters?
