Why do I see two moons in this picture?

Asked by trickface (2333points) June 1st, 2012

Look slightly above the bright moon and you will see a fainter, shadowy moon.

Is this created by the camera? Is it a shadow of the moon? if so how is this possible?

I’m thinking it’s the camera. Just like how sometimes you get those white rounds circles.

Looks like a reflection in some class. How can the moon have a shadown, by definition a shadow is dark, and it is in space. There’s nothing to cast a shadow onto.

Looks like a shadow to me

The camera lens probably has a clear filter over it to protect the lens. The second image is from that.

It’s a form of “lens flair”, like in this picture of the skylight of a church. That paler light shape below the skylight is an echo of the skylight itself produced by reflections within the inner surfaces of a compound lens.

It is an “after” image. Sometimes camera lenses can produce this effect.

@XOIIO At the risk of sounding pedantic, the Moon does indeed have a shadow. You just can’t see it until she eclipses old Sol. And on some nights, you can see the Moon below Earth’s shadow, though not in any way that would pick up detail.
So there are two lunar shadows to choose from, though the second moon in this picture is not either of them.

@Nullo However on a regular night it does not have a shadow that is visible from earth, and essentially doesn’t have one.

@XOIIO The Moon blocks Earthlight from targets behind it. If a shadow is cast and nobody’s around to observe it, does it exist?
