Please answer the following questions.

\f(Photo from APOD) Andromeda Galaxy in visible light (Photo from APOD) The Andromeda Galaxy in ultraviolet light (shifted so we can see it). Describe the differences between the two photographs of the Andromeda galaxy. e What differences are there in shapes of the galaxy, depending on the light wavelength observed? e Why is the ultraviolet picture brighter where it's brighter? (Think about star formation--which stars are brighter in ultraviolet than visible colors?) Part 2: Cosmological Ladder Create a table that lists each major step (so far) of the cosmological ladder (radar, parallax, main sequence fitting, Cepheid variables, Tully-Fisher relationship, white dwarf supernovae) and the distances that can be found for each one. Don't just copy a figure here, create your own table (that will help you remember it all better). Also, this will be a good reference for you to have in one place
