They are objects that are confined to the arms of a galaxy, i.e. objects that only exist within the spiral arms, and are not found (except very rarely) outside of spiral arms. Examples of tracers are structures to do with star formation, like for example open star clusters, giant molecular clouds or supernova remnants.
This type of galaxy is categorized as a spiral galaxy. The bulge at the center contains older stars, while the spiral arms consist of younger stars and gas and dust regions where new star formation occurs. The Milky Way is an example of a galaxy with a bulge and spiral arms.
The Milky Way galaxy has several spiral arms that extend from a central core. While the core itself contains a supermassive black hole, known as Sagittarius A*, the arms do not specifically extend from the black hole but rather spiral out from the central bulge of the galaxy.
yes, the milky way it is a barred spiral galaxy
The Milky Way galaxy has spiral arms where a lot of new stars are being born, including the Orion Arm where our solar system is located. These spiral arms are regions of higher density that promote the formation of new stars due to gravitational interactions between gas and dust.
Yes, a spiral nebula is type of galaxy much like the Milky Way.
A spiral galaxy or barred spiral.
An ordinary spiral galaxy has spiral arms coming out of the core. In a barred galaxy, the central area consists of a bar of stars and the spiral arms are attached to the ends of the bar.
It has no spiral arms.

a spiral galaxy
Our galaxy, the Milky Way, is a spiral galaxy. It consists of a central bulge surrounded by spiral arms that contain stars, gas, and dust. We are located on one of the outer arms of the galaxy.
This type of galaxy is categorized as a spiral galaxy. The bulge at the center contains older stars, while the spiral arms consist of younger stars and gas and dust regions where new star formation occurs. The Milky Way is an example of a galaxy with a bulge and spiral arms.
The arms of the Spiral Galaxy are mostly located in one plane.
Yes, a SBC galaxy is a type of a spiral galaxy. The have loosely bounded arms.
A grand design spiral galaxy (like Whirlpool Galaxy) has prominent and well defined spiral arms, whereas a flocculent galaxy (like Sunflower Galaxy) has short segments of spiral structure, "fluffy" in appearance, but without the dramatic well defined spiral arms of a grand design spiral.
