What do you call it where there is an extra space or a set of three stars between paragraphs in a book or short story?

I’m sure the book readers and writers here will know what I’m talking about.

Some action takes place in a story, and then the story shifts in location or time or whatever. Instead of one line break or carriage return between paragraphs, there will be a few. Sometimes, there will be a set of three stars separating the paragraphs.

I don’t know what it’s called, but it’s used to create a break in the narrative to let the reader know that the next paragraph is not continuing the story from exactly the same place/time/perspective as the previous paragraph. I suppose I’d like to know how it’s referred to in English grammar so I can read up some more on it.

I tried Googling this, but it’s kind of hard to put into terms that can be searched.
