The spiral galaxy M31 is the nearest example of this kind of galaxy. It
is inclined to our line of sight so that we can see structure in the
spiral arms as well as the central bulge. Observations of galaxies like
these can help us determine the structure of our own Galaxy, the Milky
Way.
This image shows M31 as seen by the Chandra telescope, an X-ray satellite in orbit above the Earth. X-ray observatories have to observe from orbit because X-rays are absorbed by the atmosphere.
