Which type of galaxy has a disk?

Which type of galaxy has a disk?

A spiral galaxy has a disk, a bulge, and a halo. The center of the galaxy is like a nucleus, containing a sphere shaped bulge that houses old stars and is devoid of dust and gas. The circular shape of the galaxy composes the disk.

Do elliptical galaxies have a disk component?

Elliptical galaxies do not have a disk. The stars may be single stars, double, or multiple stars, or may be part of clusters. Open clusters tend to be the younger of the type of clusters which appear in a galaxy. The galaxy disk also contains clouds of gas and dust, called nebulae.

Which types of galaxies have a component that is spheroidal quizlet?

-They have very little dust or cool gas, and thus have little ongoing star formation. Spiral galaxies have more gas, dust, and young stars than elliptical galaxies. Stars continue to form in the halo of our Galaxy today. All spiral galaxies have both a disk and spheroidal component to their stellar populations.

What is the most important component of galaxies?

A spiral galaxy like the Milky Way has three basic components to its visible matter: the disk (containing the spiral arms), the halo, and the nucleus or central bulge.

Which types of galaxies have a clearly defined disk component group of answer choices?

Spiral Galaxies consist of a central bulge and protruding arms. Sometimes, they have two arms that connect in a bar that crosses the center, and this is called a barred spiral galaxy. Lenticular galaxies are like a cross between spirals and ellipticals and are also disc-shaped.

What is the largest type of galaxy?

The universe’s largest-known galaxies—giant elliptical galaxies—can contain up to a trillion stars and span two million light-years across. Elliptical galaxies may also be small, in which case they are called dwarf elliptical galaxies.

Which is type of galaxy has a clearly defined disk component?

Spiral Galaxies consist of a central bulge and protruding arms. Sometimes, they have two arms that connect in a bar that crosses the center, and this is called a barred spiral galaxy. Lenticular galaxies are like a cross between spirals and ellipticals and are also disc-shaped.

What are the different types of spiral galaxies?

Spiral galaxies, barred spiral galaxies, and lenticular galaxies. If you had to pick between the main types (spiral, elliptical, and irregular), then it would be spiral. However, sometimes it is a bit more complex.

What kind of galaxy is like an egg?

Lenticular galaxies are like a cross between spirals and ellipticals and are also disc-shaped. Ellipticals are like big eggs or spheres, and irregular galaxies are unclear blobs.

What kind of galaxy is a lenticular galaxy?

Lenticular galaxies are like a cross between spirals and ellipticals and are also disc-shaped. Ellipticals are like big eggs or spheres, and irregular galaxies are unclear blobs. Peculiar galaxies do not fit into any of the other categories.
