For Ceres, Celestial Legend, the manga is the best without a doubt. I won't say anything against the anime, but after reading it, I'm stunned. It is definitely one of the best manga out there.

The stars behind the scans are NASA snapshot.

In order to get this to fit the pixels, I had to stretch the wallpaper. It is DEFINITELY better as a widescreen image. ENJOY!!

The scans are from the manga and belong to Yuu Watase.
