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.

What is a central bulge?
Nothing to be trifled with. : P In astronomy it is the almost spherical layer of stars surrounding the center hub of our galaxy. A layer in the onion, so to speak. It is a widening near the core (the centre) of a galaxy and consists of mainly very old stars. Very rare for new stars to form because of the lack of dust and gases between the stars. Surrounding this central bulge is what's called the galactic halo, which is made up of individual stars.
What is the galaxy that contains earth classified as?
The Milky Way is a spiral galaxy, more specifically a "barred spiral galaxy" in which some stars are located in a horizontal band across the nucleus, rather than in the spiral arms.
What kind of galaxy looks like a spiral galaxy except for the fact that the arms begin spiraling out from a straight line of stars instead of from the center?
You may be describing a "barred spiral" galaxy.
Is a galaxy shaped like a ball and containing only older stars most likely spiral galaxy?
It ture
What is the spherical region surrounding the disk of a spiral galaxy which contains globular clusters and reddish population II stars called?
The Galactic halo is the spherical region surrounding the disk of a spiral galaxy which contains globular clusters and reddish population II stars.
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 a Galaxy bugle?
A bulge is a tight group of stars found at the center of most spiral galaxies. The bright spot an the center of the galaxy in the picture above is the bulge. If this galaxy were seen from the side the collection of stars would create a bulge (spheroid) expanding out from the otherwise rather flat galaxy.
How are barred spiral galaxy different from spiral galaxy?
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.
What are physical charachteristcs of a spiral galaxy?
A spiral galaxy, as its name implies, has one or more spiral arms that stretch out from the center. The center often contains a bulge of stars and sometimes can even contain an active black hole.
Why do you think new stars form in the arms of a spiral galaxy and not in the enter bulge?
well, my opinion would be because of the objects and the planets in our galaxie, the spiral galaxie.
Where in a spiral galaxy is a new star found?
center bulge. i found that answer in my science galaxy book. that is what it said.
Is the milky way the same as the spiral galaxy?
The "Milky Way" is the name given to the galaxy in which we reside. The Milky Way is classified as a barred spiral galaxy type; a spiral galaxy with a central bar shaped structure composed of stars. The main galaxy classifications are spiral, elliptical and irregular .
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.
Is the Milky Way a barred spiral?
yes, the milky way it is a barred spiral galaxy
Compare the colors of spiral galaxy with the colors of elliptical galaxy?
Spiral galaxy- young stars bluish Elliptical-old stars are red
What galaxy has arms where lots of new stars are being born?

What is the milky way shaped like?
The milky way galaxy is a barred spiral shaped galaxy.
