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.

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?
en.wikipedia.org/wiki/Spectroscopy
How do you take pictures of other galaxies?
To take pictures of other galaxies, astronomers use telescopes equipped with sensitive cameras to capture light emitted by the distant galaxies. These telescopes are often placed in space or in remote locations to minimize interference from Earth's atmosphere and light pollution. The images captured are then processed and analyzed to study the properties and characteristics of the galaxies.
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?
who discovered the galaxies who discovered the galaxies
What are the types or categories for galaxies?
Spiral galaxies, barred spiral galaxies, elliptical galaxies, and irregular galaxies
What is the possessive form of galaxies?
The possessive form of "galaxies" is "galaxies'". It indicates that something belongs to or is associated with multiple galaxies.
What galaxies are sometimes called dwarf galaxies being typically smaller than spiral galaxies?
Elliptical galaxies are sometime called dwarf galaxies.
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 are the fifteen galaxies?
15 Galaxies? There are over 1,000,000,000 galaxies possibly more.
Cepheid variable stars have been used to determine the?
distance to faraway galaxies by comparing their observed brightness to their known intrinsic brightness. This relationship allows astronomers to calculate the distance to these galaxies using the Cepheid variable stars as "standard candles".
Are galaxies harmful?
no galaxies are not harmful
How are galaxies classifyed?
spiral galaxies (ours), irregular galaxies, and elliptical galaxies.
