Notes:
Edge-on galaxies like this provide astronomers with an opportunity to measure
particular aspects of spiral galaxies. In this case, astronomers can measure the velocity of
stars (by analyzing a the spectrum of the galaxy) at different distances along the disk of
the galaxy. From this they can determine a rotation curve of the galaxy which may lead to
measurements of the galaxy's mass or even mysterious things such as "dark matter."
