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.

Do galaxies change their type as they evolve?
Yes they do.Either because of gravitational attraction or by merging with other galaxies.
Why isn't the look-back time important among nearby galaxies?
Galaxies change very slowly.
Do galaxies change with the seasons because earth is traveling around the sun?
Which ones are visible at what time of day does. The galaxies themselves don't.
Do galaxies change over time explain your answer?
it changes overtime with constant movement and change in rotation
Who found the galaxies?
who discovered the galaxies who discovered the galaxies
What are the types or categories for galaxies?
Spiral galaxies, barred spiral galaxies, elliptical galaxies, and irregular galaxies
What galaxies are sometimes called dwarf galaxies being typically smaller than spiral galaxies?
Elliptical galaxies are sometime called dwarf galaxies.
The numbers of galaxies in the universe seems to be about?
We have no idea. Every time we invent a better telescope, we discover that there are 100 times more galaxies than we previously believed. There is no expectation that this will change any time soon.
When astronomers study distant galaxies they notice changes to the waves they observe describe the change to the waves they observe?
Because the universe as a whole is expanding, distant galaxies are moving away from us. As a result, electromagnetic waves emitted by those galaxies experience what is known as a red shift. Their wavelengths get longer.
What are the fifteen galaxies?
15 Galaxies? There are over 1,000,000,000 galaxies possibly more.
How time is affected between the galaxies as there is no mass there?
In fact, galaxies have an enormous mass.In fact, galaxies have an enormous mass.In fact, galaxies have an enormous mass.In fact, galaxies have an enormous mass.
