How are Galaxies born?

How are Galaxies born?

Do galaxies ever die? Have all galaxies existed since the time when galaxies were being created, or have new galaxies ever formed (other than through collision)?

Is there a life cycle of galaxies?

What is the eventual fate of a galaxy?

Thanks.

The GALEX mission is in the process of answering some of your questions.

Well, first you have a mommy galaxy and a daddy galaxy that love each other very much …
