What kind of galexies are there?
There are generally three types of galaxies: spiral galaxies, elliptical galaxies, and irregular galaxies. Spiral galaxies like the Milky Way have a disk shape with arms of stars spiraling out from a central core. Elliptical galaxies are shaped like ellipses and contain mostly older stars. Irregular galaxies have a less defined shape and tend to have a mix of young and old stars.
There are more spiral galaxies than elliptical?
the elliptical galaxy has a round or oval shape the spiral galaxy has a hurricane shape The origin of these different shapes would lie in the particular momentum of the constituent stars at the time they first coalesced into a galaxy under their mutual gravitational attraction.
What are some physical characteristics of elliptical galaxies?
Elliptical galaxies are generally round or oval in shape, lacking the distinctive spiral arms seen in spiral galaxies. They typically have a smooth and featureless appearance, with older star populations and little ongoing star formation. Elliptical galaxies also tend to be more massive and contain mainly older stars.
What population stars are found in a sprial galaxy?
Population I (High metal content) stars are generally found in the arms of spiral galaxies, whereas population II (Medium metal content) are generally found towards the centre of the galaxies.
Compare the colors of spiral galaxy with the colors of elliptical galaxy?
Spiral galaxies tend to have blue colors due to the presence of young, hot stars that emit blue light. Elliptical galaxies, on the other hand, are typically redder in color because they contain older stars that emit more red light. This color contrast is a result of the different star formation histories and compositions of the two types of galaxies.
What is a tight group of older stars located in the halo of spiral galaxies?
Global Cluster
What are facts about spiral galaxies?
milky way is a spiral galaxy spiral galaxies have younger stars in the arm and older stars in the middle
Can galaxies divided into types base on size?
are spiral galaxies are generally older than elliptical
What kind of cluster is a tight group of older stars in the halo of spiral galaxies called?
I think you are describing a "globular cluster", which are associated with older stars by most astronomers.
What is a major difference between elliptical galaxies and spiral galaxies?
Eliptical galaxies have older stars than spirals and elipticals are oval-shaped.
What are galaxies classified as?
Galaxies are classified based on their shape and structure. The main types of galaxies are spiral, elliptical, and irregular. Spiral galaxies have distinct arms of stars, elliptical galaxies are more oval-shaped with older stars, and irregular galaxies have a less defined shape.

Irregular galaxies have a less defined shape and tend to have a mix of young and old stars.
Which type of galaxy mostly consists of a collection of older red stars that are located in the center with blue and white stars located in the outer regions?
Elliptical galaxies mostly consist of a collection of older red stars in the center, with blue and white stars located in the outer regions. This is because elliptical galaxies have a smooth, featureless appearance and are dominated by older stellar populations in their central regions.
What are the unique characteristics of a spherical galaxy?
Spherical galaxies are characterized by their round shape and lack of distinct spiral arms. They contain mostly older stars and have a dense central bulge. These galaxies are often found in clusters and have a more uniform distribution of stars compared to spiral galaxies.
Are elliptical galaxies egg-shaped galaxies without spiral arms of interstellar gas and dust?
No. Elliptical galaxies are some of the oldest galaxies.They are also called early galaxies. The elliptical galaxies are made of low massed stars, a sparse interstellar medium and very low star forming characteristics.
How do the characteristics of elliptical galaxies differ from those of spiral galaxies?
Elliptical galaxies are generally round or oval in shape, with older stars and little to no gas and dust. They have less organized structure and lack spiral arms. Spiral galaxies, on the other hand, have a flat, disk-like shape with spiral arms, younger stars, and more gas and dust for ongoing star formation.
What does a spiral galaxy look like and how does its structure differ from other types of galaxies?
A spiral galaxy looks like a flat, rotating disk with spiral arms extending outwards from a central bulge. Its structure differs from other types of galaxies, like elliptical or irregular galaxies, because it has a defined disk shape with spiral arms, while other galaxies may have more irregular or rounded shapes.
