Much of "The Dark Phoenix Saga," one of the most famous X-Men stories of all time, took place in outer space. The climactic Uncanny X-Men #137 is still captivating, even if the issue may no longer be worth $2,500 to you.
In 2006, the X-Men returned to space for an extended period of time during Ed Brubaker's run on Uncanny X-Men, and hey, look, it's Professor X in a spacesuit!
Despite historically being a more grounded superhero, Batman has been to space numerous times, but perhaps never in more style than on this Golden Age-era cover of Batman #59.
In just the third issue of their own series, the Justice League of America traveled to space, though it was clearly not a vacation.
Earth's Mightiest Heroes also had some space troubles in Avengers #347, part of "Operation: Galactic Storm." If you're a superhero, the death of a galaxy tends to really ruin your day.
Then-pals Grant Morrison and Mark Millar took over The Flash for a year in the '90s, where the title character ran through space with a dude in khakis and a lady in flip-flops. (Newsarama note: Cover not actually literal.)
Deadpool in space would be fairly wacky itself, but a whole bunch of different iterations of Deadpool in space (including a disembodied head Deadpool and a double lightsaber-wielding Deadpool), on the cover of Deadpool Corps #1, is exponentially wackier.
By Brave and the Bold #155, Batman was so comfortable in outer space, that he had his own rocket ship that he used to arrest aliens from under Green Lantern's nose.
What If? #14 proved that the next natural step after Star Wars and Battlestar Galactica was indeed Sgt. Fury and his Howling Commandos in space.
Erik Larsen has taken Savage Dragon a lot of places in the book's 20-year run, so it only makes sense that the title character would wind up in outer space at some point.
Amazing Spider-Man #680 isn't Spider-Man's first trip to space, and in Peter Parker, The Spectacular Spider-Man #51 he was punching Mysterio among the stars while a terrified Debra Whitman looked on. (And yes, since the story involved Mysterio, you probably shouldn't take this cover image at face value.)
More space-punching while another character looks on in horror. This time it's between cantankerous frenemies Green Lantern and Green Arrow.
An "Assistant Editor's Month" classic, with Peter Parker's Aunt May reborn as "The Golden Oldie" and teaming up with Franklin Richards against Galactus in Marvel Team-Up #137. There's also an interstellar version of the Pillsbury Doughboy in this comic, in case you were worried it wasn't weird enough.
If there's a better way to begin a new era of greatness than with two Iron Mans floating in space, we'd like to see it.
OK, so Wonder Woman isn't really "in space" on this cover, but clearly that's what's about to happen, so it counts.
"Planet Hulk" is one of the most famous Hulk stories of the past decade, and Incredible Hulk #89 acted as a prelude. Hulk might be the strongest one there is, but even he needs an oxygen mask in the dark cold vacuum of space.
It's funny and educational! Plus, Archie with a futuristic mullet.
One of the most famous contributions during Walter Simonson's seminal Thor run was the alien Beta Ray Bill, seen here hanging tough with the God of Thunder on the cover of The Mighty Thor #350.
OK, so Lobo doesn't fit the "characters you don't normally see in space" criteria, but you have to admit it, you don't normally see dolphins in space.
As if there were any other way to end this gallery. There are just so many fascinating questions conjured by this one cover; it's truly a thing of beauty. The perfect murder? More like the perfect cover!
