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.
Do the spiral arms in your galaxy really spin?
Yes, the spiral arms in a galaxy do rotate, but not in the sense that individual stars or gas clouds are physically spinning around a central axis. Instead, they are regions of higher density that move through the galaxy as a wave-like pattern due to gravitational interactions with other objects in the galaxy.
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 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.
What population stars are found in a sprial galaxy?
Spiral galaxies contain a variety of stars, ranging from young, hot, and blue stars to older, cooler, red stars. These stars are grouped in spiral arms that extend from the central bulge of the galaxy. The different populations of stars in a spiral galaxy contribute to its overall appearance and dynamics.
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.
Match each galaxy to its description?
Milky Way: Arms extend from a core full of black holes Elliptical Galaxy: Contains mostly older stars with a red color Irregular Galaxy: Contains dust, gas, and young stars Apex :)
Is there black hole in glaxies?
Yes, there are. Most large galaxies, for example the Andromeda Galaxy or our own Milky way, have a supergiant black hole at their core. Now, in the arms of our galaxies there are thousands of black holes. So, yes, black holes do exist in galaxies. Theoretically, a black hole cannot form outside of a galaxy, because to form a black hole you require either one or two superstars, and superstars do not form outside of a galaxy or a cluster of stars.
Where in the milk way is the earth found?
The Milky Way Galaxy is either a spiral galaxy or a "barred spiral" galaxy in which the spiral arms (vaguely similar to a pinwheel) extend out from the "bar". In either event, the Sun and our solar system are about 2/3 of the way out along one of the spiral arms, and about 65,000 light years from the center of the galaxy.
What type of galaxy as curved arms?
a spiral galaxy
What kind of galaxy has arms of gas and dust?
Elliptical galaxies.
What is the name of a galaxy with winding arms called?
A spiral galaxy.
How does a lenticular galaxy differ from a normal spiral galaxy?
It has no spiral arms.
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 do spiral galaxies have a nucleus of?
A spiral galaxy nucleus contains a mass of stars in a "bulge" and is thought that many contain supermassive black holes at the very core of the nucleus.-In galaxies with tightly wound spiral arms the bulge generally contains old, red stars with low metal content (called population II stars); whereas galaxies with more loose arms generally have younger, blue stars (called population I stars). Some bulges have similarities to the elliptical galaxies and others are similar to disk galaxies.-Evidence of supermassive black holes have been discovered in many galaxies and theorized to exist in many more galaxies (at least the larger ones). Our own Milky Way Galaxy contains a supermassive black hole at its core.
Why are astronomers amazed at the clockwise-turning galaxy revealed by Hubble?
The galaxy is spinning in the direction the arms are pointing; the arms are not trailing behind.
What is a Galaxy that has a distinctive arms and a nuclear bulge?
A spiral galaxy or barred galaxy, the milky way is one.
