They always say that truth is stranger than fiction, and these pics demonstrate that well.  If an author came up with these galaxies, plenty of critiques would deride them as impractical and way over the top.

Two favorites of mine are The Sombrero,

And Starry Night,

because it’s impossible to look at these galaxies without hearing the whisper of the stories their inhabitants could tell.  My thanks to Funny Emails for the article.
