A spiral galaxy or barred galaxy, the milky way is one.
What else can I help you with?
Why do new stars form in the arms of a spiral galaxy and not in the central bulge?
Stars form in all parts of our galaxy - not just the "arms". Stars do indeed form in the central bulge. The vast majority of hot, young, blue stars are formed in the arms, but stars also form in the central bulge as well.
A galaxy with a bulge at its center and spiral arms?
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.
What type of galaxy has bulging middles and wispy arms?
A Spiral galaxy with a central bulge [See related question]
What is the shape of our 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.
What shape is the Andromeda galaxy?
The Andromeda Galaxy is spiral shaped, much like our own Milky Way Galaxy.See related link for a pictorial.
What is spirality?
a galaxy with a bulge in the middle and arms that spiral outward like a pinwheel
What galaxy arms extend from a core full of black holes?
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.
Name four different objects you can find in our galaxy?
A galaxy contains stars, gas and dust. In a spiral galaxy like the Milky Way, the stars, gas, and dust are organized into a "bulge," a "disk" containing "spiral arms," and a "halo." Elliptical galaxies have a bulge-like central region and a halo, but do not have a disk.
What is the first portion of a galaxy that forms?
The first portion of a galaxy that forms is usually the central bulge, which consists of older stars and a dense concentration of matter. This is followed by the formation of the spiral arms as gas and dust are pulled towards the center, where new stars are born.
What are the arms of a spiral galaxy?
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.
General structure of a Milky Way galaxy?
The Milky Way galaxy is a spiral galaxy with a central bulge, a disk made up of arms of gas, dust, and stars, and a halo of globular clusters. The central bulge contains older stars, while the disk is where younger stars are formed. The galaxy is surrounded by a halo of dark matter that extends beyond the visible components.
Astronomer's believe that a spiral galaxy may form?
Astronomers believe that a spiral galaxy may form through the interaction of gravity with gas and dust in space, causing these materials to clump together and rotate. Over time, protogalactic clouds collapse and form a spinning disk with a bulge at the center, giving rise to the distinctive spiral arms observed in these galaxies.
