An anthology of science fiction stories with accurate astronomy
The National Science Foundation (NSF) has helped put out a collection of
science fiction stories where the astronomical science is either accurate or
at least based in real science.
Titled Diamonds in the Sky, the entire collection may be read online here:

I have not had a chance to read any of the works yet, but the mere fact that
they aimed to be scientifically accurate is a wonder in itself.
