No, we believe that nebulae probably exist in every galaxy, and possibly between galaxies as well.
The Pillars of Creation or the Eagle Nebula is only about 7,000 light years from us, so it is definitely in the Milky Way Galaxy.
The Andromeda Nebula, now known as the Andromeda Galaxy, has no discoverer as it is visible to the naked eye. The idea that it was a galaxy and not a nebular was fist proposed in 1917 by Heber Curtis and proven in 1925 by Edwin Hubble.
