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 thank you for the annotations! Even if the image looks spectacular, this view itself is misleading in my eyes, as Earth isn’t so bright at night. The only light sources are at this point stars, the Moon, and light from the sun (in various ways), airglow and artificial light from the ground - I do like this image with a more natural view more: https://www.nasa.gov/image-detail/amf-art002e000193/
