disappearance

A disappearance occurs when something vanishes from sight. The disappearance of the stars behind the clouds makes it a bad night for watching a meteor shower.

While this word is often used when something's not visible, you can also use it for something that dies out or ceases to exist, like the disappearance of a particular animal species that's gone extinct or even disappearance of cursive writing in schools. In news stories, the word frequently refers to a crime involving a missing person: "The disappearance of his neighbor was very mysterious."
