I still remember an illustration of what Pluto was like from when I was a kid: icy forms under a dim sun and starry sky. But it turned out that in reality Pluto is far more interesting. Ice mountains, an atmosphere, and a large-appearing moon.
What's really out there is far more fantastic than our minds can conceive. But in the meantime, an art or two ain't bad.
Definitely Bonestell. As a kid when I first saw (space) art depicting a landscape as though on the surface of another moon, I was startled.
