Ummm... I know earth is IN a spiral galaxy called the Milky Way Galaxy
There are usually four types of galaxies,the first one is a SPIRAL GALAXY,the second one is a BARRED SPIRAL GALAXY,the third one is an ELLIPTICAL GALAXY,and the fourth one is an IRREGULAR GALAXY.Just in case if you want to know I believe that our galaxy, the MILKY WAY, is a BARRED SPIRAL GALAXY.
The milky way is the spiral galaxy so spiral nebulae is its part.

I dont know what you mean
It is sometimes difficult to tell; our judgment of the size of another galaxy is greatly influenced by the DISTANCE to the other galaxy, and the distance to another galaxy is sometimes tough to know with any precision. Astronomers have revised their distance estimates several times, and we cannot know that we're right THIS time. But based on what we currently believe to be true, the Milky Way is a larger-than-average galaxy similar to the Andromeda galaxy.
We know that we live in a spiral galaxy because of the shape and structure of the Milky Way, our home galaxy. Spiral galaxies have a distinct spiral shape with arms that wrap around a central bulge, and our observations of the Milky Way's structure and the movement of stars within it indicate that it fits the characteristics of a spiral galaxy.
Do you want the name of a specific one or just something that sounds more intellectual than "You know, those PINWHEEL shaped ones"? The correct terminology is spiral galaxy. As for an example, the Milky Way is a barred spiral galaxy.
Astronomers know it's a galaxy and they can measure some key characteristics. Thus they can be reasonably sure they have matched correctly it to a type of galaxy we can see.
As far as we know there are only humans in the galaxy. There may be others but we haven't found any yet. _________________ People from the Spiral Galaxy? They're lots of fun, actually... they're all screwy.
well ...thir are 3 types of galixys (that we know of) but our Galaxy is a spiral Galaxy shaped like a pin wheal.
Gallifrey is in the constellation of Kasterborous, which is in (as the TimeLords know it) Mutters Spiral, or as the humans know of it - the Milky Way.
