No, a nebula is only a few light-years across while a galaxy is thousands of light-years across.
No, a nebula is not a galaxy. A nebula is a cloud of gas and dust in space, while a galaxy is a collection of stars, gas, dust, and dark matter held together by gravity. Galaxies can contain nebulae, among other structures.
Before we realized the difference between galaxies and nebula, all the galaxies were called nebula. Nebula now are realized to be vast clouds of interstellar hydrogen or other gasses, often light years in diameter. An example is the Orion Nebula, in the middle of the sword of the constellation of Orion. This nebula, some 1500 light years away, is a nursery for stars. Galaxies, on the other hand, are vast seas of stars, millions to billions of light years away. Our galaxy is a barred spiral that contains 200 billion stars or more. Andromeda is our closest cousin (there are some smaller dwarf galaxies that are closer yet). It is a spiral galaxy 2.5 million light years away. Within some 15 billion light years in any direction one cares to look there are roughly 100 billion galaxies. That's quite a few. Those galaxies also likely contain their own nebula. Our galaxy also contains many nebula--collections of gasses that have yet to coalesce into stars, or "planetary nebula" which are gasses blown off by stars during nova or supernova events.
Nebulae are found in most galaxies
Andromeda, Milky Way These are galaxies ^ Orion Nebula Eagle Nebula
There are galaxies and nebula in every direction, including Aquarius.
nebula, dust, solar systems and other solar masses
Smaller galaxies do. Larger galaxies contain billions or even trillions of stars.
Everything, galaxies, stars, nebula, gas's, rocks.
There are many types of nebula and they can form within any galaxy. Generally, the normal types of nebula - planetary and supernova remnants will occur in the younger galaxies, so at a push spiral galaxies.

Because nebula, like galaxies, do not have a defining edge, it is difficult to determine the exact size but an estimate is the closest you'll get.However, in this case, the difference is large enough.The Tarantula Nebula is about 15 times larger than the Carina Nebula.Tarantula ~ 1,000 light years acrossCarina ~ 65 light years across.
