I'm really not sure how to interpret this curious "knob" on the left side of the galaxy's image. Four possibilities occurred to me, and I'm not sure if there could be more:
- Just some inhomogeneous part of the galaxy arm
- An interveining streak of dust
- A satellite galaxy
- A different object on the foreground
Can anyone help?

Hi tomas_depaula and welcome to the Zoo
I'd go for a star forming area in this disturbed spiral galaxy.
Hope this helps and happy hunting ! 😄
Thank you, ElisabethB!
