The moon passed between Nasa’s Deep Space Climate Observatory and the Earth allowing this rare pic showing the dark side of the moon

It looks a bit weird because the Sun is almost directly behind the camera, so there are no shadows on the crater walls. This makes the Moon look very flat. Also, the far side of the Moon doesn’t have the large dark maria (“seas”) to break up its appearance.Dynamic range is also a challenge in a picture like this as the Moon is far less reflective than the Earth. Presenting the Earth well results in a limited range of brightness for the Moon, so it has low contrast.
DSCOVR has a monochrome camera and takes a rapid succession of images through different coloured filters (red, green, blue, perhaps some other wavelengths such as UV and IR). These are combined into a colour balanced image. (Consumer cameras also have monochrome sensors but with colour filters directly grafted to them, called a Bayer filter. Neighbouring pixels see different colours.)
This is fine for DSCOVR’s day job, observing the Earth. But here the Moon is orbiting the Earth and moving across the field of view. As a result the green channel is slightly misaligned, if you look closely there is a green fringe around the Moon.
