I'm really disappointed about the image. What it shows is absolutely wrong. People, who watch it get a strange imagination of the solar system. What a pity that it was published on APOD! Shame on you.
The reasons:
1s: When a contact occurs during such an eclipse, there will neither be the effect called 'Bailey's Beads' nor a diamond ring! The corona will mostly be visible, where the sun disapperead - on Hannas image it seems that the sun has about the apparent size of earth (because the inner corona surrounds earth), but in fact it seems much smaller observed from the moon.
2nd: Furthermore the atmosphere doesn't glow in red in the illustartion - but in reality it does. The glow is so strong that we can see it during a lunar eclipse, reflected from the moon. The glow would be much brighter (yellow or white) if the sun is close to the rim.
3rd: One thing that shocked me most is that I can see surface structures of the earth in colour. What are they illuminated by? The reddish glim of the eclipsed moon could not illuminate the nightside of the earth so much. In comparison to the glowing atmosphere of the earth it would appear black and dark. Maybe one could see some citylights, but no clouds!
4th: But not enough: Some minutes ago I saw a more frustrating version on the image. It showed a wrong eclipse over the brightly illuminated lunar surface with an Apollo astronaut on it. What is the surface illuminated by? Why is it bright and white? Why do you waste your time creating such a nonsense...
