Original photo doesn't look right for me. Taking into account the lighting angle on Io and Jupiter:
- shadow must be elongated, not round.
- it cannot be Io's shadow, its shadow cone must pass almost parallel to the image plane.
your correct, the original image you are viewing is CGI. but that's where the whole "wallpapers" thing comes in. photoshopping it like that is not allowed BUT if you can edit the orbits and stuff in space engine and at last get somewhat of a good replication then that's okay for me.
HI! I would like to say that I'm just a friendly teen who loves talking and helping people out
Space engine is truly a wonderful program and the website is also very cool! Many great people here. I hope to make some good friends here.
