I enjoy language and puns. When a sentence have more than one meaning, I find that refreshing. Here are five cool space themed puns, just because space is great too:

  1. The cost of a space program is astronomical.
  2. Even though Catholics in space are weightless, do they have mass?
  3. Einstein developed a theory about space, and it was about time too.
  4. I thought about studying astronomy for university but I knew I would just be taking up space.
  5. A spacecraft took pictures of Mars and Saturn and got the best of both worlds.
