There are different types of immortal.

In Lord of the Rings, elves and Maiar/wizards (like Gandalf, Saruman, and Sauron) are immortal in the sense that they can live forever and never die of old age, but can still be killed through violence.

In, say, Dragonball Z, Garlic Jr. is immortal in that he can never die, no matter what is done to him, which is why they had to seal him away in the Dead Zone (which actually makes him seem more "gone" than the villains that died because we see them often in hell)

I'm guessing Celestia and Luna are immortal in the same way as the Lord of the Rings example
