Noon on Sedna.

I posted about Sedna a while back. Sedna is a large object discovered recently in the Oort Cloud, the most distant known planetoid in the Solar System. Here, artist Adolf Schaller — whose work will be familiar to anyone who has read the illustrated version of Carl Sagan’s Cosmos, or seen the TV series — envisions Sedna’s noontime sky, with the light of the Sun diffused by dust.
