Why do the colours differ?

    I was just wondering why the colours between the similar galaxies differ? Is it to do with the gases present?

    Almost all the bigger objects in this image are foreground stars from our galaxy. The colors, spikes and weird centers are all optical artifacts.

    Btw, always classify the object in the center of the image.
