I just got done talking with my son, the budding astrophysicist. He's doing research on galaxies that are colliding and was telling me the difference between red spheroid galaxies and blue speroid galaxies. Has to do with the most common wavelengths emitted. I believe he said our galaxies is a kind that doesn't fit between either of those, and is a green something galaxy. Our sun would actually be considered green because of something about green wavelength being where most of its light is. Don't quote me on this. Maybe some other astrophysicist posts here on DU and will see this and clarify what I'm trying to say.
