SPIRAL GALAXY
Spiral galaxies are galaxies with a central, dense area and spiraling arms. There are two types of spiral galaxies, "S" (normal spiral) and "SB" (barred spiral, with an elongated center).
Spiral Galaxy: A galaxy consisting of a flattened rotating disk of stars, a central bulge and a surrounding halo. The disk is prominent due to the presence of young, hot stars which are often arrayed in spiral patterns.
A spiral galaxy has a main disk of stars 50,000 to 150,000 light-years in diameter and a thickness up to a tenth as great. Embedded in the disk are the spiral arms, winding out from the centre like those of a pinwheel.
A spiral galaxy with a unique combination of characteristics, including powerful jets, is giving astronomers insight into the growth of galaxies early in the Universe.

This spiral galaxy is special in that it is rotating in a direction opposite to that which astronomers thought: Clockwise. Normally, spiral arms appear to be trailing behind the directions of rotation.
BARRED SPIRAL GALAXY
A barred spiral galaxy (abbreviated SB) is a spiral galaxy whose center is elongated or bar-shaped.

NGC 1260 is a spiral galaxy that was the site of the second brightest, most violent star death ever observed, the supernova SN 2006gy.
The Milky Way is a spiral galaxy, shaped like a huge whirlpool coiling around a central bulge. It takes 200 million years to rotate once. It is so big that it would take about 100 000 years to go across it from one side to the other.
The Milky Way is a spiral galaxy containing over 100 billion stars. It is over 100,000 light years (or 600,000,000,000,000,000 miles) in diameter and has a disk containing spiral arms and a dense central sphere or bulge.

Markarian 205 was reported by Weedman as a Seyfert nucleus appearing within the arms of the lower-redshift spiral galaxy NGC 4319. Most of the argument here has centered on whether or not there is a visible connection between the two.
The Milky Way has been determined to be a large spiral galaxy, with several spiral arms coiling around a central bulge about 10,000 light-years thick.
The Milky Way Galaxy is a spiral galaxy; our sun and solar system are a small part of it. Most of the stars that we can see are in the Milky Way Galaxy. The main plane of the Milky Way looks like a faint band of white in the night sky.
The spiral galaxy M63, also known as Sunflower Galaxy, has been discovered in 1779 by Pierre Mechain. The whole appearance is somewhat grainy.

In a barred spiral galaxy, a single straight cylinder of stars and gas is at the center of the galaxy.
A spiral galaxy is similar to a huge spinning plate. If you look at a spinning plate from its edge, the left part of the plate will be moving in one direction and the right in the opposite direction.
We are not completely certain but one likely mechanism is the passage of a spiral arm in a spiral galaxy.
We, including our Sun and the solar system are in one galaxy, the Milky Way Galaxy, which is a fairly typical spiral galaxy (or barred spiral galaxy).
