In DC, the Green Lantern Corps are like a sort of inter-galactic police, they monitor pretty much everything.

However, in the DCCU, it appears Krypton is the controlling government (at least for their system/galaxy etc. (like the Galactic Republic in Star Wars))

In simplest terms/examples, could someone please explain: What is Asgards role in the MCU/Marvel Comic Universe and what is role on the Nova Corps? And what is the whole deal of the Nine Realms? I know Norse Myth, but the space spin on it makes me wonder. (Is the comics version like the original myths?)

Thank you for anyone who can help.
