    By now, you have seen the Earth image by the #Artemis crew at least a hundred times. In this annotated version, several #optics effects are highlighted. It also shows how fragile planet #Earth is, with a super thin #atmosphere protecting us from the harsh vacuum of space.
    Let's protect it.

    @pfsmet so the sun, reflecting off the moon, is bright enough to illuminate Earth like that? I wouldn’t have expected that.

      @pfsmet Why did the author of this image feel the need to rotate the orientation? There's no "up" in space except for "out of the local gravity well".

          @hmallett @pfsmet if your camera/lens is good enough, yes. This photo was taken with a Nikon 5D at very high ISO, so it's brighter than it would appear normally. There's another picture that was taken with exposure settings that represent better what this view would look like to the naked eye.

            @gcvsa @pfsmet Aligning things with how most people are used to seeing them makes it easier to focus on the things that are more interesting about the photo than its orientation.

              @pfsmet Not moonlint. It's the cabin lights reflected in the window.

                @gcvsa same question here. @pfsmet any chance we can get an annotated version with the original image as seen by astronauts?

                    @das_robin @pfsmet that’s quite cool, to get that, “I never thought about what that would look like” feeling and have it instantly resolved.
