Interacting Galaxies with an Onlooker (2013)

This is another set of galaxies from the same study done on this one. This one was a bit easier to process. An interesting thing to note is that the left galaxy of the interacting pair is quite a bit more red than the one on the right. Unless my understanding is incorrect, that means it’s farther away. So, even though the one on the right appears a bit larger, it could be quite a bit smaller. The stream of stars connecting the two galaxies is likely foreshortened which helps in perceiving the depth of this situation. Meanwhile, any observers who happen to be in the galaxy below have a great view of the interacting pair but it must look quite a bit different from their vantage point.

North is up.
