Even though Hubble did not get the idea of galaxy evolution
right, today we still use his classification of galaxy types. For
Elliptical galaxies, briefly describe the difference between the
classifications of E0 and E7. Explain what the number is following
the letter "E".
For Elliptical galaxies specifically, modern observations also
revolutionized previous views of Elliptical galaxies as old and
featureless. Briefly describe at least five new observational
properties of Elliptical Galaxies that changed what we used to
think of them.
For Spiral galaxies, briefly describe five
different properties between Sa and
Sc/Sd type spiral galaxies.
