with enormous effort, a team of astronomers manages to collect enough light from a galaxy far, far away to produce a spectrum. that spectrum has lines from the elements carbon, silicon, and sulfur. this tells the team that a.the galaxy must have had an entire generation of stars that was born, lived, and died b.what they are seeing is not a galaxy at all, but the remnant of one supernova c.the galaxy must be a massive elliptical galaxy d.the galaxy must contain a quasar e.the galaxy must be closer to us than 1 billion light years
