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.
Where in a spiral galaxy is a new star found?
New stars are typically found in the spiral arms of a spiral galaxy. This is because the density of gas and dust is higher in the arms, creating the conditions necessary for star formation to occur. The gravitational forces within the spiral arms also play a role in triggering the collapse of gas clouds into new stars.
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.
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.
You are looking through your telescope at the night sky and you see a pinwheel shaped object what do you think it is?
It is likely a spiral galaxy. Spiral galaxies are characterized by their pinwheel shape and are composed of a central bulge surrounded by spiral arms containing stars, gas, and dust. Examples of spiral galaxies include the Milky Way and the Andromeda Galaxy.
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.
Which galaxy is thick in the center and has flattened arms?
A spiral galaxy or barred spiral.
What is a Galaxy that has a distinctive arms and a nuclear bulge?
A spiral galaxy or barred galaxy, the milky way is one.
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 is spirality?
a galaxy with a bulge in the middle and arms that spiral outward like a pinwheel
What type of galaxy has bulging middles and wispy arms?
A Spiral galaxy with a central bulge [See related question]

The gravitational forces within the spiral arms also play a role in triggering the collapse of gas clouds into new stars.
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.
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.

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.
