      Nebula is from (in not the) Latin for “cloud” so in short it is a cloud of dust and gases in space. I’m not sure why it’s called planetary, because it’s not got anything to do with planets – it’s thought they come about when old stars explode towards or at the end of their lives – leaving behind the big clouds of dust.
