The Andromeda Galaxy, M31, is the closest large spiral galaxy to our Milky Way. When we look at its chemical spectrum, we see that its hydrogen alpha emission line (Hα) has an observed wavelength of λobs = 655 nm.-Calculate z, being careful with the sign.-How fast is it moving in km/s?-Is it redshifted or blueshifted? Is it moving towards or away from us?
answer to three significant figures.
Imagine that you are observing the light from a distant star that is located in a galaxy 100 million lightyears
away from you. By analysis of the starlight received, you are able to tell that the image we see is of a 10-
million-year-old star. You are also able to predict that the star will have a total lifetime of 50 million years, at
which point it will end in a catastrophic supernova.
a) How old does the star appear to be to us here on Earth now?
b) How long will it be before we receive the light from the supernova event?
c) Has the supernova already occurred? If so, when did it occur?
Astronomers can determine the heat of various areas of the universe by making observations about energy they emit. Gamma rays can be found in areas where there is a lot of star formation occurring.
What would you guess about the temperature of these areas? Explain why.Do you think there would be a lot of particles present? Explain why.
