The type of galaxy that is smooth, rounded, and lacks a central disk is known as an elliptical galaxy. These galaxies are characterized by their ellipsoidal shape and contain older stars with very little interstellar gas and dust, which means they have minimal new star formation. Elliptical galaxies can range in size from small to very large and are typically found in galaxy clusters.

General structure of a Milky Way galaxy?
The Milky Way galaxy is a spiral galaxy with a central bulge, a disk made up of arms of gas, dust, and stars, and a halo of globular clusters. The central bulge contains older stars, while the disk is where younger stars are formed. The galaxy is surrounded by a halo of dark matter that extends beyond the visible components.
Name four different objects you can find in our galaxy?
A galaxy contains stars, gas and dust. In a spiral galaxy like the Milky Way, the stars, gas, and dust are organized into a "bulge," a "disk" containing "spiral arms," and a "halo." Elliptical galaxies have a bulge-like central region and a halo, but do not have a disk.
What is the Regular galaxy?
A regular galaxy refers to a type of galaxy that exhibits a distinct, well-defined shape and structure, typically categorized as elliptical or spiral. These galaxies have a uniform distribution of stars and gas, with a clear central bulge and disk in spiral galaxies, or a smooth, featureless appearance in elliptical galaxies. Regular galaxies contrast with irregular galaxies, which lack a coherent shape and often have chaotic structures. Examples of regular galaxies include the Milky Way (a spiral galaxy) and M87 (an elliptical galaxy).
What is an elongated galaxy?
An elongated galaxy, often referred to as a lenticular galaxy, is a type of galaxy that has a prominent disk shape but lacks significant spiral arms. These galaxies typically feature a smooth, featureless appearance and possess a central bulge, making them appear more elongated than spiral galaxies. They are often found in galaxy clusters and can contain older stars and less interstellar gas and dust compared to their spiral counterparts. Examples of elongated galaxies include NGC 5866 and NGC 1023.
How would you describe the composition of spiral galaxies?
Spiral galaxy has 3 basic components to its visible matter: the disk, the halo, and the nucleus or central bulge.
What is a huge spiraling disk of stars and dust and gas called?
A huge spiraling disk of stars, dust, and gas is called a galaxy. The Milky Way is an example of a galaxy that contains our solar system.
Is Milky Way sphirical or elliptical in shap and why?
The Milky Way is both disk-like and spiral in shape. It is a barred spiral galaxy, meaning it has a flat, rotating disk with spiral arms emanating from a central bar. This shape is common among spiral galaxies due to the rotation of stars and gas in the galaxy.
What kind of galaxy is shaped like a disk and ressembles a pinwheel?
A "spiral" galaxy.
What does a spiral galaxy look like when seen edge-on?
When seen edge-on, a spiral galaxy appears as a thin, flat disk with a bulging central region. The disk is often darkened by dust lanes along its plane, giving it a more defined edge. The spiral arms are not visible from this perspective.
What Is thin gas and clusters of stars surrounds the disk of the milky way galaxy?
what is the thin gas and clusters of stars surrounds the disk of the Milky Way Galaxy.
What is the surface area of a disk?
Smooth
What shape is the Andromeda galaxy?
The Andromeda Galaxy is spiral shaped, much like our own Milky Way Galaxy.See related link for a pictorial.
