Dune, the centerpiece, eponym, and (in a sense) main character of Frank Herbert's most acclaimed novel. If you share even a fraction of my affection for the story/world, you're certain to enjoy " 'Dune' concept art shows the evolution of David Lynch's sci-fi vision" (for Lynch's 1984 film realization).

From out-of-this-world to what-in-the-world? ... if my preceding selection happened to offend you, perhaps I can redeem myself by being dismayed with this show of sexism within the genre: "Science Fiction Forum Shuns Women Writers: Warp Speed to the 'Assholocene Era'?"
Which demise is your guilty pleasure?
And in a final, near-other-worldly note, "NASA Tries to Rewrite the Book on Science Fiction." I wasn't one of the invitees to NASA Goddard Space Flight Center for this outreach -- but I'm confident it was a lot of fun and will enhance a lot of stories.
(That prediction didn't require me going out on a limb. For seven years I was a NASA contractor, primarily supporting GSFC. In 2009, by then writing SF full time, I attended the then-NASA-subsidized Launchpad workshop: a week-plus astronomy boot camp for authors run by University of Wyoming astronomer [and sometimes SF author] Mike Brotherton. Yet more recently I consulted extensively with NASA scientist [and sometimes SF author] Geoffrey A. Landis in "building" a two-mile-square powersat and choosing a space rock to become Earth's second moon for my novel Energized. All that NASA influence certainly contributes to my world-building.)
Now I'm off to work on yet newer worlds ...
