What kind of galaxy has arms of gas and dust?
Elliptical galaxies.
Do elliptical galaxies are egg-shaped galaxies without spiral arms of interstellar gas and dust?
yes
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.
What are galaxies that have very bright centers and very little dust or gas called?
elliptical
What are similarities between elliptical and spiral galaxies?
While spiral galaxies are bright, elliptical galaxies are dim. Spiral galaxies are hotbeds of star formation, but elliptical galaxies aren't nearly as prolific because they contain less gas and dust, which means fewer new (and brighter) stars are born
What are some physical characteristics of elliptical galaxies?
Elliptical galaxies are made of old stars and not very much gas or dust.
Galaxies that have a bright center that contains very little dust and gas?
Stars come in a variety of types. Blue stars, which are very hot, tend to have shorter lifetimes than red stars, which are cooler. Regions of galaxies where stars are currently forming are therefore bluer than regions where there has been no recent star formation. Spiral galaxies seem to have a lot of gas and dust, while elliptical galaxies have very little gas or dust.
How are the spiral and elliptical galaxies the same?
Both contain large numbers of stars, plus dust, gas, and magnetic fields.
What types of galaxies tend to be made up of very old stars and contain very little gas and dust matter?
elliptical
Are nebulas in elliptical galaxies?
Because of their age, elliptical galaxies are believed to have older stars and less gas and dust in their insterstellar medium than other types of galaxies, and thus their nebulae are less common. However, nebulae are presumed to exist in almost all galaxies; and some recent observations hint that the central black holes of elliptical galaxies may tend to preserve interstellar gas by preventing it from cooling enough for star formation.
What determines the shape of a galaxy?
That is related to their past history. Many galaxies have undergone collisions with other galaxies; this takes out most of the interstellar gas, and the galaxies can no longer form new stars. If I remember correctly, such galaxies will change into elliptical galaxies.That is related to their past history.

What type of galaxy includes little gas and dust and no longer produces stars?
the galaxy that contains no blue stars is I DO NOT KNOW and i would like to know the answer too
