67 Space Puns That Are Out of This World

Space has been on my mind a lot lately because my neighbor got one of those backyard telescopes and now every clear night he’s out there narrating constellations to nobody. It’s sweet. It’s also incredibly annoying at 11pm. Anyway, it got me thinking about space puns, and once you start, you genuinely cannot stop, they just keep orbiting back around.

1. The Classic Opener

How do you organize a space party? You planet.

I know. You’ve heard it. Your aunt posted it on Facebook in 2014. But it’s the foundational text of space punnery and I won’t pretend otherwise.

2. Saturn’s got range

Saturn’s name is the best in our solar system. It just has a nice ring to it.

3.

I need my space.

4. The Breakup

Why did the star break up with the other star? They needed space.

These two back-to-back feel like the same pun wearing different hats, and honestly? They are. I don’t care. Moving on.

5.

What’s an astronaut’s favorite key on the keyboard? The space bar.

This one’s an Instagram caption waiting to happen. Picture of a cocktail, zero context, just “found the space bar 🍸🚀”, you’re golden.

6. Genuinely proud of this cluster:

• Red shift happens.
• Dark matter of opinion.
• Event horizon-tally speaking.

The red shift one is doing WORK. If you know, you know. If you don’t, the universe is expanding and light stretches toward the red end of the spectrum and, look, just trust me, it’s good.

7.

Orion’s Belt is a huge waist of space.

Three stars. Terrible pun. Waist. Waste. Belt. I’m not gonna apologize for this one even though I probably should.

8.

My kid is obsessed with the moon. I’m hoping it’s just a phase.

9. The Restaurant Review

Why didn’t people like the restaurant on the moon? No atmosphere.

This is one of my favorites because it works on like three levels if you think about it long enough. Ambiance. Literal air. The fact that you’d die. Comedy gold across the board.

10.

Don’t take things so Siriusly.

11.

I told my friend I was reading about black holes. She said “sounds like a dark matter of opinion.” I told her we can’t be friends anymore.

12. For the texters

Bloom where you’re planet-ed. 🌱🪐

Send this to someone who just moved to a new city. They’ll either love you or block you. Both outcomes are acceptable.

13.

What kind of music do planets like? Neptunes.

14.

Einstein released his theory about space, and it was about time too.

Space-time. Get it? Spacetime? This pun has been around longer than general relativity itself, probably. Still lands.

15. Quick fire round

• What do astronauts put on their toast? Space jam.
• What kinds of fish live in space? Starfish.
• What does a space turkey say? Hubble, Hubble, Hubble.

That turkey one is so stupid. I love it so much.

16.

You rock-et my world.

17. The Hair Salon

How does the man in the moon cut his hair? Eclipse it.

18.

Comet me, bro!

(Perfect text to send before game night. Or a fistfight. Context-dependent.)

19.

Why didn’t the Sun go to college? He already had a million degrees.

20. Okay this one’s a stretch

What do you call a space magician? A flying saucerer.

I know. I KNOW. Sorcerer. Saucerer. It barely works. The mouth has to do weird things to make it happen. Including it anyway because the image of a magician on a flying saucer is inherently funny and I will die on this hill.

21.

What did Mars say to Saturn? Give me a ring sometime!

22.

Why does the Moon go to the bank? To change his quarters.

Side note, I spent twenty minutes trying to make a pun about Lagrange points and got absolutely nowhere. Some things in space resist being funny. Lagrange points are one of them. The Roche limit is another. If anyone’s cracked a Roche limit pun, email me immediately.

23. The Spaghetti One

You know how when something falls into a black hole it gets stretched into long thin strands? That’s literally called spaghettification. Real term. Real science. So naturally:

Pasta la vista, baby.

This is the best pun on this list and I’m not being humble about it. The universe handed us spaghettification on a silver platter and we owe it to science to make the joke.

24.

Her story was pretty nebula-s.

Nebulous. Nebula. Vague like a cloud of interstellar gas. Yeah, it’s fine. It’s fine!

25.

I have a problem with my astronaut friends, they never Apollo-gize.

26. The Finance One

How do you finance a spaceship? Buy now, pay crater.

27.

Wormhole-y moley!

This is garbage and I’m not sorry.

28.

I told someone I light-yearn for them and they just stared at me. Which is fair. “Light-yearn” requires you to squint at the wordplay the same way you squint at actual stars. But I stand by it, it’s romantic in a nerdy, slightly desperate way.

29. The Exercise Plan

What’s the Sun’s favorite exercise? The solar cycle!

30.

Pulsar-prise party! 🎉

Okay this one barely qualifies as language. Pulsar. Surprise. I’m reaching and my arms are very tired.

31.

You’re over the moon!

32.

A star walks into a bar. The bartender says “you look familiar.” The star says “I get that a lot, I’m pretty stellar.” The bartender says “no, you were in here last night and didn’t tip.” Stars. No class despite all that gas.

33. The Closet Defense

“Why didn’t you put away your laundry?”

“My closet is already outer space.”

Gonna start using this one irl tbh.

34.

What’s a quick space bath? A meteor shower.

35.

Black hole in one! ⛳

36. The Obscure Corner

Don’t trit-on me. 🐍

This one’s for the Neptune’s-moon-knowing crowd specifically. Triton. Tread on. The Gadsden flag but make it astronomical. Niche? Absolutely. Do I care? Not even a little.

37.

Quit your waning and phase it already.

Waning. Whining. Phase. Face. Moon phases. I actually think this is kinda clever? The double wordplay happening simultaneously, wait, I said I wouldn’t use that word. The double wordplay happening at the same time elevates it above your standard moon pun.

38.

What do you call a crazy spaceship? A lunar-tic.

39.

You know what the Voyager golden record really is? An out-of-this-world mixtape.

Launched in 1977, still traveling, carrying Chuck Berry and whale sounds into the void. If aliens ever find it, they’re gonna be so confused. That’s not a pun, that’s just a fact.

40. The Diet

“Why’d you go on a diet?”

“I want to weight-less.”

41.

Cosmic ray of sunshine. ☀️

Caption-ready. Screenshot it. Post it. Tag me.

42.

How much ice cream do you want? A Big Dipper, please.

43. Neutron Star

No tea, Ron!

This is astronomically stupid. Neutron. No tea Ron. I can’t believe I typed it. I can’t believe you read it. We’re both worse for this experience.

44.

Hubble trouble.

45.

There’s no mer-cur-y for what ails me.

Mercury. Mercy. Cure. There’s actually three things happening in this one if you break it apart and I think it deserves more credit than it gets. This is the underrated middle child of space puns.

46. The Proton

Don’t proton to be someone you’re not.

Proton. Pretend. Look, I didn’t say every pun on this list would be a winner.

47.

Why couldn’t the star stay focused? He kept spacing out.

48.

Hold on a moon-ute.

I just realized I’ve been writing space puns for a while now and haven’t mentioned Pluto. Which feels appropriate because NASA hasn’t mentioned Pluto as a real planet since 2006. Still too soon for some people.

49. Justice for Pluto

Pluto’s not a planet anymore, but it’s still a planet to me. That’s not a pun. That’s a stance.

50.

What’s the best board game to play in space? Moon-opoly!

Bad. Very bad. The kind of pun a dad makes and then looks around the room waiting for acknowledgment that never comes.

51. The Oort Cloud

For the uninitiated: the Oort Cloud is a theoretical shell of icy objects at the very edge of our solar system. For the pun-itiated: it’s basically space’s junk drawer.

The Kuiper Belt, meanwhile, is just space suspenders. Holding everything up out past Neptune.

52.

Exo-planet: my ex’s world. I don’t live there anymore.

53.

What do you get when you cross Santa with a spaceship? A U-F-Ho-Ho-Ho.

December content. Pin this for later.

54. I’m genuinely proud of this one

You call a parsec a parsec, but I see them rolling. They hatin’.

Parsec. A unit of distance equal to about 3.26 light-years. Also sounds like “park” if you’re willing to commit to the bit, which I always am. Han Solo famously misused this term and I will never let it go.

55.

Quantum leap year only happens every 4 dimensions.

56.

You’re really in the ozone today.

57. The Sign-Off

Quasar-ely yours.

Sincerely. Quasarly. Quasar-ely. I’m squinting at this one myself. It’s the kind of pun that works better written down than spoken aloud, which is convenient because this is a blog.

58.

What’s between diet and supper? An asteroid belt.

Ate-steroid. ATE. STEROID. Between meals. This one creeps up on you. Give it a second.

59.

• Star-struck.
• Supernova-caine (the astronomer’s painkiller).
• Nebula-fied.

Three compound word puns in a trench coat pretending to be clever. The supernova-caine one is actually kinda ngl my favorite of the bunch, it sounds like something a space dentist would prescribe.

60. The Singularity

A singularity is truly one of a kind. That’s literally what it means. It’s a point of infinite density at the center of a black hole, and also the laziest pun on this entire list, and I’m choosing to end on it because sometimes things just collapse in on themselves.

61.

I love you with all my heart and solar. ❤️🌞

Solar. Soul. Send this to someone you love. Or someone you want to mildly annoy. Same difference sometimes.

62.

Big Bang theory? Explosive start, but the show went on too long.

63.

A white dwarf is just a small but dense ex-star. Kinda like my coworker Dave. (Sorry Dave. You’re very bright for your size.)

64.

Red giant: basically a tomato in space. Look it up. I’m right.

65. The Escape

Escape velocity: can’t touch this. 🔨

MC Hammer understood astrophysics better than any of us gave him credit for.

66.

Will you stop by the dairy on the way home? Sure, it’s on my Milky Way.

Puns are so capricorn-y. That doesn’t fully make sense and idk if Capricorn counts as a space pun or an astrology pun, but the line between astronomy and astrology is thinner than people want to admit. (Astronomers, please don’t email me. I know the line is not thin. I’m doing a bit.)

67.

Space rocks.

Two words. Double meaning. Efficient. Sometimes less is more, which is also what they said when they demoted Pluto.

Anyway. I started this because my neighbor won’t stop pointing his telescope at Jupiter and yelling about the Great Red Spot, and now I’ve written sixty-something space puns and honestly? I think I get it now. The void is funny. The void has always been funny. Quasar-ely yours. 🚀
