You think THAT's weird? Well, humans (as well as pretty much everything alive except bacteria) are really symbiotic organisms, much like the CueCappa - but not on the organismic level, but on the CELLULAR Level - about a billion years ago, some protozoa decided to absorb these other protozoa with whom they had this symbiotic relationship - we now call those second set of protozoa "mitochondria" and "chloroplasts"!

Well OK, maybe the galaxy stuff IS more impressive... "bar of ancient red supergiants" sounds almost like something you'd find in a vault in Angband, too
