that the "smaller, dimmer NGC 3165 at bottom right" is visible in the image.

<<NGC 3165 ist eine Spiralgalaxie (Sdm) im Sternbild Sextant. Sie wurde 1856 von William Parsons entdeckt. Die Galaxie NGC 3165 interagiert mit den Galaxien NGC 3166 und NGC 3169, wie in dem rechten Bild zu sehen ist.

And what about the astrologers whose zodiac would be rapidly changing!

Quadruple tidal gravitational forces drop off as the inverse cube of the distance
Hence, the local zodiac, itself, would change very slowly; and basically:

• We will all go together when we go.
  Ev'ry Capricorn and every Virgo.
  Universal bereavement,
  An inspiring achievement,
  Yes, we all will go together when we go.

The description also mentions that the galaxy NGC 3165 can be seen but that isn't visible in this image.

Today's APOD Explanation appears to be unraveling as in this comic scene.

Well, a star can't move faster than the speed of light, so if it was originally located, say, twenty thousand light-years from the "edge" of the galaxy (whatever we mean by such an "edge"), it can't take less than twenty thousand years for it end up in intergalactic space. (But I'm sure the math whizzes at this site can give you a better answer.)

What would be the consequences for the star, if it was flung out of its parent galaxy?

That's an easy one. None.

There could be a wonderful consequence for the astronomers living on any habitable planet in that system, in one direction of the night sky there would be 2 magnificent galaxies to examine close up and in the other the grand expanse of the rest of the universe to ponder over with no localized sources in the way

This picture is a cropped version of APOD from March 28, 2013 and the commentary is exactly the same. But the attribution is different.

Today's picture (06-November-2015) does not look like the same picture as 28-March-2015, rather, it's the same objects by a different photographer, hence the attribution is different. In any case, since the objects are the same the text could be recycled, although it's not exactly the same (e.g., the relative location of NGC 3169 has been appropriately changed from "left" to "top").
