People seriously under-estimate Wiki's quality control team. It's not like any one can write anything and it stays up. If you look at the end of most lines on Wiki, there will be a little blue number in brackets that will take you down to the "sources" section of the page. There you will find a list of the sources that Wikipedia user's have used. So, for example, if there was a source from "thisgoesagainstmyopinionsoitmustbewrong.com" then it would tell you. If there is a claim with no source it will usually say "Citation needed" instead of a link to the source.

"Astronomy offers an aesthetic indulgence not duplicated in any other field. This is not an academic or hypothetical attraction and should require no apologies, for the beauty to be found in the skies has been universally appreciated for unrecorded centuries."
