How many different types of galaxies are situated throughout the universe?

Edwin Hubble devised a classification scheme for the galaxies in the visible universe. It has three fundamental classes of galaxies:
These categories are divided into subclasses. The so-called 'Hubble tuning fork diagram' shows these.

there are countless numbers of Galaxies, and seriously, not even the physicists in NASA know how many
But you should know the TYPES of galaxies and they are Elliptical and spiral; If you are going fancy also irregular.
Galaxies contain stars (sun etc) solar systems, planets, asteroids etc. Examples include Milky way galaxy!
Galaxies are part of the universe, which begun 14bn years ago from a single "dot"
^ these are the things you really need to know and maybe also the string theory, how there are multi-verses which means multi universes, but that like REALLY high grade stuff most teachers don't credit
