The Milky Way galaxy is what's called a "barred spiral" galaxy; there are two "bars" of stars, and the spiral arms extend like a pinwheel from the bars. Scientists think it looks somewhat like NGC1300.
The Sun and our solar system are, we think, somewhere about 1/3 to 1/2 of the way out from the center, although from inside the Milky Way, it is challenging to determine exactly where we are. This is probably a good distance to be, since we believe that there is a supermassive black hole in the center of the Milky Way.
In about 4 billion years, our galaxy will collide with the Andromeda galaxy, and we can only speculate about the eventual shape of the merged galaxy. We expect that several billions of stars with their attendant solar systems (if any) will be flung off into intergalactic space by the gravitational interactions. Our Sun, which will probably have become a red giant star by that time, might be one of them.
we are located within one of its spiral arms.
The shape of the Milky Way (our galaxy) is the shape of a spiral.
A spiral galaxy has the shape of a pinwheel. Our solar system is in a spiral galaxy that we call the Milky Way.
milky way and it has a circular shape
Irregular galaxy
Saturn is a planet in our solar system, so Saturn's galaxy is the earth's galaxy, and so forth. Saturn's galaxy (our galaxy) is the Milky Way. The Milky Way is a spiral [shaped] galaxy.
It depends what shape the galaxy has.
irregular galaxy
First of all, it's a spiral galaxy, not an spiral galaxy. Second, a spiral galaxy would have a spiral shape, obviously.
An Irregular Galaxy is a galaxy that has no shape or form as defined by the classes of the "Hubble sequence" An Amorphous galaxy is a galaxy that has neither spiral nor elliptical in shape as defined by "The Atlas of Peculiar Galaxies". See related links for pictorial representation
Our galaxy is a spiral galaxy because it is spiral in shape.
