Non-SMAC sites
Site about the Alpha Centauri system Pretty good, check out the links at the bottom as well. Site about "Chiron and Friends". This is not related to SMAC, since this Chiron is an "object" in space, in our own solar system, astronomers do not agree how to classify it, so I just call it an "object". A bit funny if you're interested. Also has the Chiron symbol.
