Ionized Carbon Emission in NGC 7331

Because NGC 7331 is viewed at an incline, there is a marked difference in the ionized carbon emission observed in different parts of the galaxy, depending on our observing perspective. Emission from within the delineated donut shape varies between the side of the galaxy that is closer to us (lower sector) and its far side (upper sector). This shows that viewing perspective has an effect on the origin of the ionized carbon emission observed.
