Color. The type of star effects the color. Like temperature wise. Spiral galaxies are generally more blue than elliptical galaxies due to its stars. Size is another characteristic along with luminosity.

∙ 10y agoSize, mass and type.
Size would be length, width in lightyears.
Mass is usually of lesser interest but is very important in the motion of the galaxy.
The main types of galaxies are irregular, elliptical and spiral (like our own Milky Way)

How does a spectroscope enable astronomers to determine the characteristics of distant stars and galaxies?

What are some physical characteristics of elliptical galaxies?
Elliptical galaxies are made of old stars and not very much gas or dust.
Are elliptical galaxies egg-shaped galaxies without spiral arms of interstellar gas and dust?
Yes, that is correct. Elliptical galaxies are characterized by their elliptical or egg-shaped appearance and lack spiral arms of interstellar gas and dust. Unlike spiral galaxies, which have a flattened disk shape with spiral arms, elliptical galaxies have a more rounded or elongated shape. They are composed mainly of older stars and contain little to no ongoing star formation. Elliptical galaxies also tend to have less interstellar gas and dust compared to spiral galaxies.
Who found the galaxies?

What are the types or categories for galaxies?
Spiral galaxies, barred spiral galaxies, elliptical galaxies, and irregular galaxies
What galaxies are sometimes called dwarf galaxies being typically smaller than spiral galaxies?
Elliptical galaxies are sometime called dwarf galaxies.
What are the fifteen galaxies?

Are galaxies harmful?
no galaxies are not harmful
What are the theories of the galaxies?
The two main theories of galaxy formation are the bottom-up theory, where galaxies form from mergers of smaller structures like dwarf galaxies, and the top-down theory, where galaxies form from the gravitational collapse of large gas clouds. The hierarchical model is a popular framework that combines aspects of both theories to explain the variety of galaxy shapes and sizes observed in the universe.
How are galaxies classifyed?
spiral galaxies (ours), irregular galaxies, and elliptical galaxies.
What is the possessive form of galaxies?
The possessive form for the plural noun galaxies is galaxies'.Example: Their galaxies' paths do not coordinate.
