Yes.
It's difficult to be certain; we're inside the Milky Way galaxy, and we've never seen it from the outside. For a long time, astronomers believed that the Milky Way was a classical spiral galaxy, but more complete observations indicates that it is actually a barred spiral galaxy.
They are in space. (: you're welcome.
You cant tell the size of a galaxy depending on what Astronomers call it. A spiral galaxy could be 100 light years wide,and an irregular could be over 10,000 light years across, or visa versa.
Older stars are generally towards the centre of a galaxy as they will be the first to accumulate around the galactic centre. Because they are older, there is less "free" hydrogen, so new star formation will occur wherever, there is enough matter to form a new star. This generally is around the outer edges of a galaxy.
The Milky Way was long thought to be a "spiral" galaxy much like the Andromeda Galaxy . But recent observations indicate that the Milky Way is probably a "barred spiral" galaxy. Viewing the Milky Way from within as we do, it is somewhat difficult to get a clear picture.
A Spiral Galaxy
Stars form in the great clouds of gas and dust in the spiral arms of a galaxy.
An irregular galaxy is just a galaxy in a iregular shape(odd). most gallaxies form ecliptal(round) ,spiral and barred spiral An irregular galaxy is usally an early galaxy or just a galaxy with a odd shape.
The higher gas density forms stars more efficiently, so all the gas is converted into stars before a disk can form.
Our Galaxy, the Milky Way is a barred spiral galaxy. It means it is spiral in form and has a central bar. Pictures explain the concept better.See related links for a pictorial representation of our galaxy.

well, my opinion would be because of the objects and the planets in our galaxie, the spiral galaxie.

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
