What else can I help you with?
Three quarters of all known galaxies are what galaxies?
That is a difficult question to fully answer as types of galaxies are not fully defined. A ball park figure would be dwarf galaxies, or spiral galaxies depending on the area in question. See related question for a full breakdown.
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.
How do you compare elliptical spiral and irregular galaxies?
You cant tell the size of a galaxy depending on what Astronomers call it. A spiral galaxy could be 100 light years wide,and an irregular could be over 10,000 light years across, or visa versa.
Do all galaxies follow the law of gravity?
That is what has been observed, except that spiral galaxies rotate faster than would be expected based on the matter we can see. Thus we infer the existence of dark matter in the rims of these galaxies. An alternative hypothesis is that something is terribly wrong with our theory of gravity. To the best of our knowledge the rules of physics are the same no matter where you go.
How do spiral galaxies form?
Spiral galaxies form from the collapse of a protogalactic cloud. Spiral galaxies consist of three components: a rotating disk, a bulge and a halo. Spiral galaxies, like the Milky Way, owe their shape to stars inside the protogalaxy developing at different intervals. The gas between forming stars continues to be compressed, and the resulting gravitational differences manhandle the protogalaxy's stars, dust and gas. When the protogalactic cloud collapses, the stars in the bulge and halo form first. These stars have rather random orbits around the galactic center. The galactic center probably contains a supermassive black hole, which likely exerts some gravitational influence on the formation of a spiral galaxy. The remainder of the cloud forms a disk due to the conservation of angular momentum (the same effect as the spinning up of the dancer when she pulls her arms inside). This motion forces everything into a rotating disk, and additional differences in gravity build the spiral arms. Oppositely, when a protogalaxy's stars develop at the same time, you have an elliptical galaxy on your hands. The stars in the disk form later and thus the disk population of stars are younger than those in the bulge and the halo. Further, the stars in the disk rotate around the center of the galaxy in a collective, well defined way unlike the stars in the bulge and halo.

What is most common galaxies?
there are 3 types of galaxies. 1.spiral 2.elliptical 3.irregular the main galaxy in our universe would be a spiral galaxy
What is the 3 different kinds of galaxies in order?
Any "order" would be arbitrary. The main types are spiral galaxies, elliptical galaxies, and irregular galaxies. Several variations exist, too.
What term would you use to describe the shape of the milky way?
Spiral.
How would you describe the introduction in a composition?
describe introduction in a composition
What scientist discovered the three main types of galaxies?
spiral galaxies elliptical galaxies and irregular galaxies
How can astronomers make a mosaic of 100 billion galaxies in the universe of every shape size and color?
Astronomers could make this complex mosaic on the side of a large building, but it is unlikely that they would be able to include all 100 billion galaxies (i.e. 60 billion spiral/barred spiral galaxies, 20 billion lenticular galaxies, 15 billion elliptical galaxies, and 5 billion irregular/peculiar galaxies).
How would you describe the composition of the ocean?
Regarding the composition of ocean water, I would describe it as a homogeneous mixture, or solution.
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.
In which type of galaxy would you be most likely to observe a massive star supernovae in a giant elliptical galaxy or in a large spiral galaxy?
Large Spiral Galaxy. This is because they contain more of the OB stars that are required for a supernova event. Elliptical galaxies tend to be older and have more low mass stars and are not as common as spiral galaxies. See Link for more information
Which of these galaxies would you most likely find at the center of a large cluster of galaxies a a large spiral galaxy b a giant elliptical galaxy c a small irregular galaxy?
B.) A giant elliptical galaxy
How would you describe your body type and composition?
Strong and Healthy
