Let me begin by saying how much I enjoy the wonderful and inspiring photos shown on APOD by the many talented amateur and professionals who submit them. It really breaks up a boring day to view these images.
The image of NGC 891, posted today, Feb. 25, 2010 looks to be slightly wavy, note right side how it dips as compared to the left side. I was wondering if perhaps this is indicative of all or most spirals or if perhaps, as I have seen in photos of galaxies in collision, showing that some gravitational influence has caused this effect––or am I just imagining the wave.
