Using the ideas discussed in the text, in what sense are we "star stuff"? - Nearly every atom from which we are made was once inside of a star When did humans learn that the Earth is not the center of the universe? - Within the past 500 years How are galaxies important to our existence? - Galaxies recycle material from one generation of stars to the next, and without this recycling we could not exist. If we imagine the history of the universe compressed into one year, dinosaurs walked...

The Andromeda Galaxy is faintly visible to the naked eye in the constellation Andromeda. Suppose instead it were located in the same direction in space as the center of the Milky Way Galaxy (but still at its current distance). How would it appear to the eye in that case? a) It would be much brighter because it would be illuminated by the many stars in the center of our galaxy. b)It would look about the same, but it would be harder to pick out because its cloud-like appearance would m...
