∙ 11y agoElliptical galaxies are thought to form when two spiral galaxies collide and merge. Whereas spiral galaxies are dominated by flattened, rotating disks of stars and gas, elliptical galaxies are round, smooth collections of stars.

∙ 13y agoMost elliptical galaxies contain mainly older stars.
Very little star formation is thought to occur, because of the lack of gas, dust, and space.
Because of this, they appear yellow red, which is in contrast to the distinct blue tinge of a typical spiral galaxy, a colour from the young, hot stars in its spiral arms.

∙ 9y agoNo, Globular clusters are characterized by the fact that they are not forming new stars. The fact that they are not and have not formed new stars for some time (they are made of "Population II" stars) can be seen by looking at a Hertzsprung-Russell diagram for a Globular cluster.

∙ 11y agoAstronomers tend to think so. Ellipticals and the core regions of spiral galaxies are poor in dust, so the assumption is that evolving stars have swept it up. By contrast, the arms of spiral galaxies are dust-rich, and this allows new stars to form.

∙ 13y agoGenerally elliptical galaxies have old stars. There is no, if any, new star formations.
Wiki User
∙ 11y agoElliptical galaxies are called so because of their peculiar shape. The number of stars in these galaxies may change galaxy to galaxy. So there is no saying how many stars.

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.
There are more spiral galaxies than elliptical?
the elliptical galaxy has a round or oval shape the spiral galaxy has a hurricane shape The origin of these different shapes would lie in the particular momentum of the constituent stars at the time they first coalesced into a galaxy under their mutual gravitational attraction.
What type of galaxy contains mostly young stars?
The age of an individual star can vary; they were all made at different times and have different life spans. Stars can range from a few million to a several billion years old. The oldest star yet discovered, HE 1523-0901, is an estimated 13.2 billion years old.
Compare and contrast the three types of galaxies?
Galaxies that appear to have a bulge in the middle and arms that spherical outward, like pinwheels, are spherical. Elliptical galaxies look like round or flattened balls. Galaxies that do not have regular shapes are known as irregular galaxies.
What are four general shapes of galaxies?
Galaxies have different shapes because of what happens throughout their lives. Any galaxy, at one point or another, will encounter another or many galaxies. When encounters occur, gravity takes over. The larger of the two galaxies will consume the smaller one, this is called galactic cannibalism. The act of absorbing another galaxy will change the size of the galaxy it's shape and even the speed of its rotation. Our own galaxy, The Milky Way, is as large it is (100000-150000 Light years across.) because of galactic cannibalism. The Milky Way is as we speak consuming two other small galaxy. And in about 2 billion years, our nearest nieghbor, the Andromeda Galaxy, will collide with our galaxy. Both the Milky Way and Adromeda galaxy are spiral galaxies, but after they collide the resulting new galaxy will an elliptical galaxy, which looks like a bright white sphere.
Along with shape and size which property distinguishes spiral galaxies elliptical galaxies and irregular galaxies from one another?
You can also distinguish them by the types of stars - older stars versus younger stars, and stars of different "metallicity".
The types of Galaxies?
Spiral,elliptical,and irregular galaxies
What is one way that an elliptical galaxy differs from the other types of galaxies?
Elliptical galaxies are large blob shaped galaxies that most galaxies will eventually look like. Elliptical galaxies are what happens when two or more large galaxies collide and coalesce.
What types of galaxies tend to be made up of very old stars and contain very little gas and dust matter?
elliptical
What are the 3 common galaxies?
galaxie 1, 2, 3, 4 and 5
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.
What are the types or categories for galaxies?
Spiral galaxies, barred spiral galaxies, elliptical galaxies, and irregular galaxies
Describe all the categories of galaxies?
the three main types of galaxies are spiral, elliptical and irregular spiral contains spiral arms contained gas, dust and they help new stars form
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.
Can galaxies divided into types base on size?
are spiral galaxies are generally older than elliptical
There are more spiral galaxies than elliptical?
the elliptical galaxy has a round or oval shape the spiral galaxy has a hurricane shape The origin of these different shapes would lie in the particular momentum of the constituent stars at the time they first coalesced into a galaxy under their mutual gravitational attraction.
What are three types of galaxys?
The three different types of galaxies are the Spiral galaxy, the Elliptical galaxy, and the Irregular galaxy. Spiral galaxies are obviously in the shape of a spiral, elliptical galaxies are shaped as an ellipse, or a flat circle, and irregular galaxies can be any shape.
